Craig Year: 2001, 2008, 2005 1 Acknowledgements 2 3 The completion of this work in large part can be attributed to the efforts of the 4 U.S. Fish and Wildlife Service Arcata Field Office staff and in particular to Mr. 5 Thomas Shaw for providing much of the supporting site-specific field data, 6 habitat mapping, and fisheries data used in the analyses. The efforts of the 7 various Tribal fisheries personnel were critical in supplying additional fisheries 8 collection data, and intensive site substrate and cover mapping. In particular, the 9 efforts of Tim Hayden, Charlie Chamberlain and Mike Belchik. USGS personnel 10 from the Midcontinent Ecological Science Center also provided valuable 11 assistance and field data used in the cross section based hydraulic and habitat 12 modeling. Mr. Gary Smith and Mike Rode of the California Department of Fish 13 and Game also provided critical information on site-specific habitat suitability 14 criteria and conceptual foundations for the escape cover analysis used in the 15 habitat simulations. Much of this work was also supported by work of Tim 16 Harden (Harden and Associates). The Bureau of Reclamation also provided 17 valuable input during the Phase II study process on Klamath Project operations. 18 A special thanks is also given to Mr. Mike Deas (U.C. Davis) for providing water 19 temperature simulations below Iron Gate Dam. The Technical Team also 20 provided critical input and review of all technical elements of this work as well as 21 providing reviews of the report. Finally, the completion of this work would not 22 have been possible without the tireless efforts of Jennifer Ludlow, Mark 23 Winkelaar, James Shoemaker, Shannon Clemens, Jerilyn Brunson, William 24 Bradford, Sarah Blake, Brandy Blank, Matt Combes, Leon Basdekas, and Aaron 25 Hardy at the Institute for Natural Systems Engineering, Utah State University. 26 27 Executive Summary 28 29 Previous instream flow recommendations developed as part of Phase I (Hardy, 30 1999) recommended interim instream flows in the main stem Klamath River 31 based on analyses of hydrology data. At that time, site-specific data suitable for 32 analysis and evaluation using habitat based modeling were not available. This 33 report details the analytical approach and modeling results from site-specific 34 studies conducted within the main stem Klamath River below Iron Gate Dam 35 downstream to the estuary. Study results are utilized to make revised interim 36 instream flow recommendations necessary to protect the aquatic resources 37 within the main stem Klamath River between Iron Gate and the estuary. This 38 report also makes specific recommendations for future research needs as part of 39 the on-going strategic instream flow studies being undertaken by the U.S. Fish 40 and Wildlife Service and collaborating private, local, state, federal, and tribal 41 entities. 42 43 This report was developed for the Department of the Interior (DOI) who provided 44 access to a technical review team composed of representatives of the U.S. Fish 45 and Wildlife Service, Bureau of Reclamation, Bureau of Indian Affairs, U.S. 46 Geological Survey, and the National Marine Fisheries Service. The technical Draft - Subject to Change 1 review team also included participation by the Yurok, Hoopa Valley, and Karuk 2 Tribes given the Departments trust responsibilities and the California Department 3 of Fish and Game as the state level resource management agency. The 4 technical review team provided invaluable assistance in the review of methods 5 and results used in the analysis, provided comments on draft sections of the 6 report, and provided data and supporting material for use in completion of the 7 Phase II report. In addition, several agencies and private individuals provided 8 written comments on the Preliminary Draft Report, which have been addressed in 9 this report where appropriate. 10 11 This report is organized to follow the general process used to implement the 12 technical studies. It first provides important background information on the 13 historical and current conditions of the anadromous species, highlights factors 14 that have contributed to their decline, provides an overview of the Phase I study 15 process and its principal findings. The report then continues with a description of 16 the Phase II technical study process. Key sections address methods and 17 findings for each technical component such as study design, study site selection, 18 field methods, analytical approaches, summary results, and recommended 19 instream flows. 20 21 The Phase II study relied on state-of-the-art field data collection methodologies 22 and modeling of physical habitat for target species and life stages of anadromous 23 fish. The field methods were directed toward achieving a three-dimensional 24 representation of each study site that incorporated between 0.6 to over one mile 25 of river depending on the specific study site. At each study site, a spatially 26 explicit substrate and vegetation map was developed and then integrated with 27 the three-dimensional channel topography in GIS. Fieldwork also involved 28 collection of hydraulic calibration data and fish observation data. The later 29 information was used in the development of habitat suitability criteria, conceptual 30 habitat model development and implementation, and habitat model validation 31 efforts. 32 33 Hydrology in the main stem Klamath River below Iron Gate Dam was estimated 34 differently for different purposes in Phase II. For example, we used simulated 35 unimpaired inflows (i.e., no depletions) to Upper Klamath Lake routed to Iron 36 Gate Dam with no Klamath Project imposed water demands. This simulated 37 scenario represents the best available estimates of the unimpaired flows below 38 Iron Gate Dam for the purposes of this study. The remaining flow scenarios 39 included the use of Upper Klamath Lake net inflows, historical Klamath Project 40 water demands, and the USFWS Biological Opinion (2000) target Upper Klamath 41 Lake water elevations. These scenarios represent different potential operational 42 flow scenarios as points of reference to the instream flow recommendations 43 developed as part of Phase II. Differences between these simulated flow 44 scenarios required the use of different models and/or modeling assumptions. 45 The assumptions and modeling tools are described in the appropriate technical 46 sections of the report. The estimated hydrology at each study site was used in Draft - Subject to Change 1 both the physical habitat modeling and temperature simulations using the USGS 2 Systems Impact Assessment Model (SIAM) or its components. 3 4 Physical habitat modeling at each study site relied on two-dimensional hydraulic 5 simulations that were coupled to three-dimensional habitat models. The 6 analytical form of the habitat models varied for spawning, fry, and 'juveniles' (i.e., 7 pre-smolts). These modeling results were compared to available 1-dimensional 8 cross section based hydraulic and habitat modeling at study sites that overlapped 9 between existing USFWS/USGS and Phase II studies. 10 11 Habitat suitability criteria for target species and life stages of anadromous fish 12 were developed from site-specific data for Chinook spawning, Chinook fry, and 13 steelhead 1+. These curves were validated both by field observations using the 14 habitat modeling results as well as by comparison to results from an individual 15 based bioenergetics model for drift feeding salmonids developed at USU. A 16 separate procedure was developed to obtain habitat suitability curves for Chinook 17 juvenile (i.e., pre-smolts), steelhead fry, and coho fry based on available 18 literature data. This approach used a systematic process to construct an 19 'envelope' habitat suitability curve that encompassed the available literature 20 curves. The overall process included a validation component that compared the 21 habitat versus discharge relationships between envelope curves to the site- 22 specific curves for Chinook spawning, Chinook fry, and steelhead 1+. The results 23 validated the use of the envelope curves for use as interim criteria pending 24 further research and development of site-specific curves for these species and 25 life stages within the Klamath River. 26 27 Habitat modeling involved the integration of substrate and cover mapping with 28 the three-dimensional topography and hydraulic properties at each study site with 29 the habitat suitability curves. Habitat modeling was undertaken for Chinook 30 spawning, fry, and juveniles, coho fry and juveniles, and steelhead fry and 31 steelhead 1+. Different habitat models were developed for spawning, fry, and 32 juveniles. The study generated a salmonid fry habitat model that incorporated a 33 distance to escape cover that also required sufficient depth within the escape 34 cover in order for it to be utilized at a given flow rate. This model also 35 incorporated quantitative differences in the type of escape cover. 36 37 The habitat modeling results for each species and life stage were validated 38 against the spatial distribution of each species and life stage surveyed at study 39 sites at different flow rates. These results generally demonstrated that the 40 integrated habitat modeling was validated for the study in terms of spawning and 41 fry life stages. Our assessment of the pre-smolt or juvenile life stage results is 42 that they are consistent for the existing habitat model assumptions. However, we 43 discuss what we perceive to be inherent biases in these results (juveniles) based 44 on the existing habitat model structure and make specific recommendations of 45 what additional work would likely improve the results for this particular life stage. 46 Draft - Subject to Change jjj 1 Temperature simulations based on the unimpaired flow regime below Iron Gate 2 Dam were conducted with HEC5Q as part of the SIAM applications. These 3 results supported the findings in Phase I that flows lower than ~ 1000 cfs during 4 the late summer would likely increase the environmental risk to anadromous 5 species due to almost continual exposure to chronic temperature thresholds. We 6 believe that these simulation results show that there is very little flexibility for 7 reservoir operations at Iron Gate Dam to mitigate deleterious flow dependent 8 temperature effects. This finding has previously been reported by the USGS 9 (Bartholow 1995) and Deas (1999). 10 11 The integration of the habitat modeling with the unimpaired hydrology was used 12 to develop habitat reference values for target species and life stages at each 13 study reach on a monthly basis for flow exceedence ranges between 10 and 90 14 percent. The reference habitat value was computed as the percent of maximum 15 habitat associated with the unimpaired flow values for each species and life 16 stage on a monthly basis. This reference habitat value was used as one 'target' 17 condition to guide the selection of monthly flow recommendations at a given 18 exceedence flow level. 19 20 The flow recommendation process also employed a prioritization of species and 21 life stages to be considered within the year and/or within a specific month. The 22 prioritization of life stages was taken from the life history sequence of 23 anadromous species (i.e., spawning, fry, and then juveniles). The initial priority 24 order for species was defined as Chinook, then coho, and finally steelhead. It is 25 stressed that this initial prioritization was used to conceptually simplify the flow 26 recommendation process only, and that all species and life stages were 27 examined as part of the overall analysis. The process then relied on an iterative 28 procedure to select target flows for each month at a given exceedence level. 29 This procedure attempted to pick a target flow that would simultaneously 30 preserve the underlying characteristics of the seasonal unimpaired hydrograph at 31 that exceedence flow, the underlying relationship of the unimpaired hydrograph 32 between all exceedence flow levels, while striving to maximize habitat for the 33 priority species and life stages relative to the unimpaired habitat reference 34 conditions. The corresponding monthly flow rates at each exceedence level 35 were then used to compute the percent of maximum habitat for all other species 36 and life stages in a given month. These values were then compared to their 37 respective unimpaired habitat values to ensure that adequate protection of 38 habitat for non-priority species and life stages remained reasonable. 39 40 The flow recommendations developed in the Iron Gate to Shasta River Reach 41 were 'propagated' downstream to each successive reach by addition of the reach 42 gains as presently defined by the USGS in their MODSIM module of SIAM. It is 43 recognized that these reach gains reflect existing depletions in tributary systems 44 (e.g., Shasta and Scott Rivers) but are the only estimates presently available for 45 use in the simulation models for the system. The flow recommendations for each 46 river reach were then used to compute the percent of maximum habitat on a Draft - Subject to Change 1 monthly basis for each species and life stage. The recommended flow based 2 calculation of percent of maximum habitat for each species and life stage was 3 then compared against the associated unimpaired flow based habitat values. 4 5 Although flow recommendations were developed for the 10 to 90 percent 6 exceedence range (i.e., nine water year types), five water year types were 7 identified representing Critically Dry, Dry, Average, Wet, and Extremely Wet 8 inflow conditions for Upper Klamath Lake. These water year classifications 9 parallel those developed for the Trinity River and were used as operational 10 definitions in the Phase I report. Furthermore, the USBR KPSIM model was 11 modified to use this five-water year type format for simulating operations under 12 different instream flow requirements below Iron Gate Dam. The 90, 70, 50, 30, 13 and 10 percent exceedence flow levels were assigned to each of these water 14 year types, respectively (i.e., critically dry to extremely wet). This assignment 15 was used to demonstrate several key points regarding the use of 16 recommendations at this level of resolution (i.e., five water year types) and how 17 the existing operational models for the Klamath Project simulate flow scenarios. 18 19 These five water year type dependent recommendations were utilized in the U.S. 20 Bureau of Reclamation's Klamath Project Simulation Module (KPSIM) to simulate 21 project operations over the 1961 to 1997 period of record. This analysis 22 confirmed that the project could be operated to achieve these recommendations 23 in all but 19 of the 468 simulated months in this period of record. These results 24 also highlighted that an alternative water year 'classification' strategy for 25 specifying instream flows should be considered in lieu of a five water year type 26 scheme. We provide a specific recommendation of how this could be 27 approached based on the instream flow recommendations developed in Phase II. 28 29 30 Draft - Subject to Change Title: Evaluation of Interim Instream Flow Needs in the Klamath River Phase II Final Report Author: Hardy, Thomas B; Addley.

This simulated 37 scenario represents the best available estimates of the unimpaired flows below 38 Iron Gate Dam for the purposes of this study. The remaining flow scenarios 39 included the use of Upper Klamath Lake net inflows, historical Klamath Project 40 water demands, and the USFWS Biological Opinion (2000) target Upper Klamath 41 Lake water elevations. These scenarios represent different potential operational 42 flow scenarios as points of reference to the instream flow recommendations 43 developed as part of Phase II. Differences between these simulated flow 44 scenarios required the use of different models and/or modeling assumptions. 45 The assumptions and modeling tools are described in the appropriate technical 46 sections of the report. The estimated hydrology at each study site was used in Draft - Subject to Change 1 both the physical habitat modeling and temperature simulations using the USGS 2 Systems Impact Assessment Model (SIAM) or its components. 3 4 Physical habitat modeling at each study site relied on two-dimensional hydraulic 5 simulations that were coupled to three-dimensional habitat models.

These modeling results were compared to available 1-dimensional 8 cross section based hydraulic and habitat modeling at study sites that overlapped 9 between existing USFWS/USGS and Phase II studies. 10 11 Habitat suitability criteria for target species and life stages of anadromous fish 12 were developed from site-specific data for Chinook spawning, Chinook fry, and 13 steelhead 1+. These curves were validated both by field observations using the 14 habitat modeling results as well as by comparison to results from an individual 15 based bioenergetics model for drift feeding salmonids developed at USU. A 16 separate procedure was developed to obtain habitat suitability curves for Chinook 17 juvenile (i.e., pre-smolts), steelhead fry, and coho fry based on available 18 literature data. This approach used a systematic process to construct an 19 'envelope' habitat suitability curve that encompassed the available literature 20 curves. The overall process included a validation component that compared the 21 habitat versus discharge relationships between envelope curves to the site- 22 specific curves for Chinook spawning, Chinook fry, and steelhead 1+. The results 23 validated the use of the envelope curves for use as interim criteria pending 24 further research and development of site-specific curves for these species and 25 life stages within the Klamath River. 26 27 Habitat modeling involved the integration of substrate and cover mapping with 28 the three-dimensional topography and hydraulic properties at each study site with 29 the habitat suitability curves. Habitat modeling was undertaken for Chinook 30 spawning, fry, and juveniles, coho fry and juveniles, and steelhead fry and 31 steelhead 1+. Different habitat models were developed for spawning, fry, and 32 juveniles. The study generated a salmonid fry habitat model that incorporated a 33 distance to escape cover that also required sufficient depth within the escape 34 cover in order for it to be utilized at a given flow rate. This model also 35 incorporated quantitative differences in the type of escape cover. 36 37 The habitat modeling results for each species and life stage were validated 38 against the spatial distribution of each species and life stage surveyed at study 39 sites at different flow rates. These results generally demonstrated that the 40 integrated habitat modeling was validated for the study in terms of spawning and 41 fry life stages. Our assessment of the pre-smolt or juvenile life stage results is 42 that they are consistent for the existing habitat model assumptions. However, we 43 discuss what we perceive to be inherent biases in these results (juveniles) based 44 on the existing habitat model structure and make specific recommendations of 45 what additional work would likely improve the results for this particular life stage. 46 Draft - Subject to Change jjj 1 Temperature simulations based on the unimpaired flow regime below Iron Gate 2 Dam were conducted with HEC5Q as part of the SIAM applications. These 3 results supported the findings in Phase I that flows lower than ~ 1000 cfs during 4 the late summer would likely increase the environmental risk to anadromous 5 species due to almost continual exposure to chronic temperature thresholds.

This finding has previously been reported by the USGS 9 (Bartholow 1995) and Deas (1999). 10 11 The integration of the habitat modeling with the unimpaired hydrology was used 12 to develop habitat reference values for target species and life stages at each 13 study reach on a monthly basis for flow exceedence ranges between 10 and 90 14 percent. The reference habitat value was computed as the percent of maximum 15 habitat associated with the unimpaired flow values for each species and life 16 stage on a monthly basis.

The corresponding monthly flow rates at each exceedence level 35 were then used to compute the percent of maximum habitat for all other species 36 and life stages in a given month. These values were then compared to their 37 respective unimpaired habitat values to ensure that adequate protection of 38 habitat for non-priority species and life stages remained reasonable. 39 40 The flow recommendations developed in the Iron Gate to Shasta River Reach 41 were 'propagated' downstream to each successive reach by addition of the reach 42 gains as presently defined by the USGS in their MODSIM module of SIAM. It is 43 recognized that these reach gains reflect existing depletions in tributary systems 44 (e.g., Shasta and Scott Rivers) but are the only estimates presently available for 45 use in the simulation models for the system. The flow recommendations for each 46 river reach were then used to compute the percent of maximum habitat on a Draft - Subject to Change 1 monthly basis for each species and life stage. The recommended flow based 2 calculation of percent of maximum habitat for each species and life stage was 3 then compared against the associated unimpaired flow based habitat values. 4 5 Although flow recommendations were developed for the 10 to 90 percent 6 exceedence range (i.e., nine water year types), five water year types were 7 identified representing Critically Dry, Dry, Average, Wet, and Extremely Wet 8 inflow conditions for Upper Klamath Lake. These water year classifications 9 parallel those developed for the Trinity River and were used as operational 10 definitions in the Phase I report. Furthermore, the USBR KPSIM model was 11 modified to use this five-water year type format for simulating operations under 12 different instream flow requirements below Iron Gate Dam. The 90, 70, 50, 30, 13 and 10 percent exceedence flow levels were assigned to each of these water 14 year types, respectively (i.e., critically dry to extremely wet). This assignment 15 was used to demonstrate several key points regarding the use of 16 recommendations at this level of resolution (i.e., five water year types) and how 17 the existing operational models for the Klamath Project simulate flow scenarios. 18 19 These five water year type dependent recommendations were utilized in the U.S. 20 Bureau of Reclamation's Klamath Project Simulation Module (KPSIM) to simulate 21 project operations over the 1961 to 1997 period of record. This analysis 22 confirmed that the project could be operated to achieve these recommendations 23 in all but 19 of the 468 simulated months in this period of record. These results 24 also highlighted that an alternative water year 'classification' strategy for 25 specifying instream flows should be considered in lieu of a five water year type 26 scheme. We provide a specific recommendation of how this could be 27 approached based on the instream flow recommendations developed in Phase II. 28 29 30 Draft - Subject to Change Close

Natural Resources Conservation Service Year: 2004, 2005 1 i California Oregon Cover Photo: Lower Klamath National Wildlife Refuge at sunset Tupper Ansel Blake/ USFWS Map Detail Area: Upper Klamath River Basin ii T he Klamath River Basin presents numerous challenges as well as opportunities for its many water users. For years, farmers and ranchers in the basin have recognized the vital role they play in the health of their watershed. Working with conservation districts, the Natural Resources Conservation Service ( NRCS) and others, land managers continue to proactively find ways to enhance natural resources in the basin, benefiting wildlife and the environment. However, as it has across the western United States, drought hit home in the Klamath for those who depend on every drop of water to sustain their livelihood, culture and community. In the spring of 2001, the combination of drought and the impact of the Endangered Species Act triggered a shutdown of irrigation water during the growing season, drying up water resources to more than 2,000 farms and ranches. NRCS, in cooperation with local conservation districts, provided a quick infusion of technical assistance and $ 2 million in cost- share funding for cover crops through the Emergency Watershed Protection Program. As cover crops took hold, the seeds of a long- term solution took root in the NRCS/ conservation district partnership. The ability of the local office to receive funding, engage community members and other partners, plan resource improvements, implement actions, and monitor success proved to be an invaluable asset for the community. Helping private landowners develop and apply practical, common- sense solutions to complex resource issues will be the challenge of the conservation partnership well into the future. USDA, in concert with the locally led conservation districts, will continue to play a critical role by delivering technical and financial assistance to Klamath Basin farmers and ranchers. The Rapid Subbasin Assessments that follow are the first step in that process. The assessments are designed to help local decision- makers determine where investments in conservation will best benefit wildlife habitat, agriculture and other land uses in a compatible manner. It is our goal to provide a comprehensive overview of resource challenges and opportunities in the basin, and help decision- makers to prioritize their investments in areas that will best sustain multiple use of natural resources in the basin now and in the future.

Stretching across southern Oregon and northern California, the Klamath Basin has become synonymous with the water challenges that western water users face. As one example, agricultural commodities that need irrigation water to thrive – providing Americans with the cheapest domestic food supply in the world, face competition from the critical water needs of sucker fish, salmon and other threatened and endangered species. While that competition is understandable, more and more, conservation leaders in all industries have come to recognize that these water needs aren’t necessarily at odds with one another, and can in fact be compatible. While an example of the challenges today’s agricultural producers and conservationists face, the Klamath Basin has emerged as an example of how diverse interests can work together successfully. 2 Overview of the Upper Klamath Basin Upper Klamath Basin Description The Upper Klamath Basin is an area of high desert, wetlands, and the Klamath River. The river extends 250 miles from its headwaters at Upper Klamath Lake in south central Oregon to the west coast of northern California. The Upper Klamath Basin includes the US Bureau of Reclamation’s ( USBR) Klamath Project Area and the drainage area above Irongate Dam on the Klamath River. The basin’s lakes, marshes, and wetlands host an abundance of plant and animal species and include national wildlife refuges, parks, and forests. Agricultural production began around the turn of the 20th century, and with the creation of the Klamath Irrigation District in 1905, water diversions for irrigation began in earnest. A portion of these irrigated lands are in the USBR’s irrigation project. The ‘ project area,’ as it is commonly called, includes 188,000 of the 502,000 acres of private irrigated land in the basin. This includes lands leased from the various wildlife refuges that are supplied with water by the USBR. Privately irrigated acreages can vary from year to year, depending on USBR contracts and annual cropping cycles. In comparison, the majority of the private irrigated land - about 314,000 acres - in the basin is located outside the project area. Upper Klamath Basin Quick Facts: • Over 2.2 million acres are privately owned in the Upper Klamath Basin • 188,000 of the irrigated acres are in the US Bureau of Reclamation’s Irrigation Project • Approximately 502,000 acres of privately owned lands are irrigated • 314,000 acres of irrigated lands are outside the Project area 3 Overview of the Upper Klamath Basin The Role of Agriculture in the Basin Agricultural lands play a key role in a healthy ecosystem. Located on the Pacific Flyway, migratory birds like the American White Pelican and the Red- Necked Grebe use croplands in the Klamath Basin as an important feeding and resting stop. Deer graze on wheat and barley fields, and pheasants use both crop and rangelands for their nesting and feeding grounds. Progressive conservation leaders recognize that farming and fish and wildlife habitat are not mutually exclusive. Well- maintained farmland creates fish and wildlife habitat, contributing to a healthy watershed. They also recognize that opportunities will always exist to improve the condition of natural resources in the basin. To address those opportunities, conservation leaders in Oregon’s Klamath Falls Soil and Water Conservation District and California’s Lava Beds/ Butte Valley Resource Conservation District have proactively identified four key priorities tied to natural resource conservation. The districts asked experts at the USDA’s Natural Resources Conservation Service to help them develop a plan to determine what could be done on- farm to conserve water, increase water storage, improve water quality, and enhance fish and wildlife habitat. While so much of the attention to date in the Klamath Basin has been focused on water demand, these conservation leaders recognize demand is only one piece of the puzzle. Comprehensive solutions must also address water quality, storage and wildlife habitat. Conservation District Priorities 1) Conserve Water 2) Increase Water Storage 3) Improve Water Quality 4) Enhance Fish & Wildlife Habitat 4 Rapid Subbasin Assessments Conserving natural resources is the ultimate goal throughout the basin, and its success hinges on long- term solutions. At the request of local conservation districts, NRCS undertook an 18- month study of resource concerns, challenges and opportunities throughout the Upper Klamath Basin. The study was not intended to provide a detailed, quantitative analysis of the impacts of conservation work, but rather, to provide an initial estimate of where conservation investments would best address the districts’ four priority resource concerns. Beginning in the spring of 2002, NRCS planners collected information to enable the conservation districts, agencies, organizations, farmers, ranchers and others to make informed decisions in a timely manner about conservation and resource management in the basin. These Rapid Subbasin Assessments are intended to help leaders set priorities and determine the best actions to achieve their goals. As a part of the rapid subbasin assessment process, eight subbasins were delineated ( see map at left). A watershed planning team traveled through each subbasin, inventorying agricultural areas, identifying conservation opportunities and current levels of resource management, and estimating the impacts of these opportunities on the Conservation in the Upper Klamath Basin 5 Conservation in the Upper Klamath Basin conservation districts’ priority resource concerns. They focused their recommendations on areas that would provide the best benefit to the wide array of stakeholders in the Upper Klamath Basin. They also identified a number of socio- economic factors that must be taken into consideration when helping producers adapt to new management styles and conservation activities. Through NRCS, conservation districts and other federal, state and local entities, private land managers are working to identify ways they can more efficiently use – and share – the water they need. In the face of increasingly complex and politically polarized circumstances, a clear purpose and direction has arisen. The commitment of the local conservation partnership to identify the impacts of water shortages and to find solutions that will improve natural resource conservation will be key to the long- term viability of both endangered species and industries in the Upper Klamath Basin. The information that follows provides a summary of the conservation challenges and opportunities that NRCS staff found in their assessment. Recommendations for where financial and other resources can best be invested to improve natural resources, while sustaining the economy of the Upper Klamath Basin, are also identified. 6 Conservation in the Upper Klamath Basin Private Lands Conservation Accomplishments One component necessary to understanding future conservation opportunities in the basin is to recognize the current conservation work of private land managers. An indicator of these efforts is the work that has been undertaken in partnership with NRCS and the local conservation districts. In federal fiscal years 2002 and 2003, Upper Klamath Basin farmers and ranchers improved resource conditions on 18,877 acres of privately owned agricultural lands, with assistance from NRCS and the conservation districts. During this time, private land managers have worked with the conservation districts in the basin to: • improve the condition of 11,800 acres of grazing lands • conserve water and improve water quality on 13,656 acres • restore and establish 4,138 acres of wetlands and riparian areas • improve 281 acres of forest stands • establish resource management systems on 1,351 acres of cropland These conservation efforts were accomplished with a combination of private, state and federal funding. 7 Conservation in the Upper Klamath Basin Summary of Conservation Opportunities In addition to recognizing current conservation activities, the assessments define what can be accomplished with a strong conservation partnership in the Upper Klamath Basin. All too often, the debate about multi- use of water in the basin has focused on ways to reduce water demand. However, the basin’s many water users - including fish and wildlife - benefit just as much from improvements to water quality, water storage and wildlife habitat. Taken together, the recommendations that follow seek to utilize a comprehensive approach to all four resource priorities - with the goal of contributing to a sustainable, multi- use water system. While quantification of the results of conservation work in these four areas is difficult, there is no question that a comprehensive approach to natural resource improvement in the Upper Klamath Basin will result in accumulative long- term benefits for endangered fish species, wildlife habitat, agriculture, urban and other water uses. Agriculture cannot undertake these efforts alone. Private landowners and the general public both benefit from natural resources conservation in the Upper Klamath Basin. Because of this, public and private sources of funding from in and outside the region are necessary. Solutions of this magnitude also come with other social, political, and cultural costs. Upper Klamath Basin Quick Facts: • 1,400 farm families live in the Upper Klamath Basin • The Upper Klamath Basin is home to sucker fish, bull trout and redband trout 8 Conservation in the Upper Klamath Basin For example, all stakeholders in the Upper Klamath Basin need to identify and address social, economic, and cultural resource- based values they have historically enjoyed. Politically, there must be resolution and agreement on water rights, endangered species, and water quality. Water Conservation Because few water use measurements have been taken in the past, it is difficult to quantify where specific water efficiencies can be gained. Throughout the Upper Klamath Basin, water that leaves one irrigated field generally re- enters streams or enters the groundwater, providing the opportunity for it to be utilized again later. Because of this, water delivery systems both in and outside the USBR project area are generally efficient. As a result, the most significant benefit of reducing water demand on individual farms is an improvement in water quality and reduction in water temperatures, rather than an increase in available water. 9 Conservation in the Upper Klamath Basin Conservation measures that reduce water demand on private agricultural lands can be accomplished in a variety of ways. New technologies for managing when and where water is applied on crop and pasture lands will help to ensure that water is only applied when it is of the best benefit to the plant. Water conservation opportunities include improving irrigation water-use efficiency, retaining and conserving drainage water, and making use of new technologies that more accurately forecast the impacts of drought and floods. The subbasin assessments indicate an opportunity to conserve water and improve water quality on 130,000 acres of irrigated lands within the USBR project. Outside the project area there is an opportunity for water conservation on approximately 220,000 irrigated acres. If all potential conservation practices are implemented on all irrigated lands, on- farm water use efficiency could increase by up to 25 percent in the Upper Klamath Basin. A potential two to five percent increase in water yield could be achieved by increasing management in upland range and forestland areas. In all cases, these are preliminary estimates and require validation. This estimate does not account for evaporation, transpiration, seepage or other loses that may occur at the sites receiving conserved water nor does it evaluate irrigation delivery or conveyance efficiencies. Tupper Ansel Blake/ USFWS 10 Conservation in the Upper Klamath Basin This level of water conservation cannot be reached without a concerted federal/ state/ private partnership that works together to apply water conservation practices in targeted areas throughout the Upper Klamath Basin. Improving Water Quality Water quality has a direct impact on many fish and wildlife species. Within the Upper Klamath Basin, most rivers and lakes do not meet federally mandated Clean Water Act standards for temperature, dissolved oxygen, pH, or other pollutants. Water quality is affected by water temperature, low in- stream flows and the condition of adjacent land riparian areas, among other items. Private landowners are just one of many groups who have an opportunity to improve water quality throughout the basin. Water quality improvement opportunities on private agricultural lands in the basin range from improving the management of livestock near streams and rivers to utilizing new technologies that track pest and weed cycles to ensure that pesticides are only applied when they will be most effective. Water conservation practices that reduce tailwater runoff from irrigated fields can provide extensive improvements in water quality. 11 Conservation in the Upper Klamath Basin Increasing Water Storage/ Yield In recent years, drought has been a large contributing factor to reduced water levels in the Upper Klamath Basin. One solution to address low water flows would be to store water for times of water shortage. There are at least two challenges to this solution: finding a place to store water and finding water to store. To evaluate this option, potential storage values were calculated for 41 years of record from 1961 to 2002. This analysis reinforced the observation that, as has been seen in recent years, drought years normally occur in a multi- year cycle. Because of this, in the years where extra water is most needed, it is often not available from previous years to store. One promising, small- scale, water storage solution may lie in subsurface irrigation water storage in suitable locations, such as the Tulelake Subbasin. In this scenario, there exists a potential to store water in the soil profile and reduce irrigation water demand during the irrigation season. Another option for subsurface storage of water includes the restoration of streams and their surrounding wetlands and riparian areas. This can increase the “ sponge” effect allowing for the slow release of water through the long, dry summer months. Tupper Ansel Blake/ USFWS 12 Conservation in the Upper Klamath Basin Enhancing Fish and Wildlife Habitat The Upper Klamath Basin is home to a wide variety of aquatic and terrestrial species of wildlife and fish. Much of the water used in the Klamath wildlife refuges and associated marshes, ponds, streams and wetlands originates in the Upper Klamath Lake Subbasin. The Klamath Basin wildlife refuges provide a stopover for 85 percent of the ducks, geese, and other birds that migrate through the Pacific Flyway from Alaska to South America. Streams in the Upper Klamath Basin provide spawning and rearing habitat to threatened and endangered suckers and bull trout, as well as redband trout, which is listed as a species of concern by the US Fish and Wildlife Service. Several streams are highly valued “ catch and release” sport fisheries. There is high landowner and public interest in restoring and maintaining riparian habitat along these streams. Many of the conservation opportunities outlined under water conservation and water quality provide direct benefits to fish and wildlife as well. In addition, creating and restoring wetland areas, planting trees and developing wildlife habitat along the edges of crop fields all contribute to enhancing wildlife habitat in the basin. Tupper Ansel Blake/ USFWS 13 Conservation in the Upper Klamath Basin Overview of Conservation Effectiveness In order for the Upper Klamath Basin to successfully move forward with solutions, agriculturists, environmentalists, Tribes, government agencies, organizations, and others need to develop unified leadership to arrive at a common vision for the future. In addition, stakeholders and others must commit to a long- term investment of public and private funding as well as other resources. Based on the Upper Klamath Basin Rapid Subbasin Assessments, the Oregon and California NRCS planning staff rated the potential benefit of recommended conservation practices and resource management systems based on the conservation districts’ four resource priorities. Many state and federal agencies have invested in conservation work throughout the basin. While the recommendations in this document focus on private land and agriculture, the assessments can also be applied to help prioritize conservation practices on other land uses basin- wide. Overall, based on the planning team’s analysis, conservation activities in the Sprague River Subbasin would produce the greatest benefit, and conservation practices in the Upper Klamath River East Subbasin would yield the least Tupper Ansel Blake/ USFWS overall benefit based on the conservation district’s priorities. 14 Conservation in the Upper Klamath Basin While recognizing that any science- based conservation focus in the Upper Klamath Basin would be beneficial, the charts on pages 18- 19 specifically focus on work that can be accomplished on private lands. They provide a breakdown of recommended conservation practices on each of the conservation districts’ priorities by subbasin. For example, the water demand chart shows that investing in conservation practices in the Sprague River Subbasin has the greatest potential for reducing agriculture’s water demand by implementing improved irrigation practices. The Sprague also provides the best opportunity to address water quality and wildlife habitat. Investment in conservation activities in the Tulelake and the Upper Klamath Lake subbasins offers the greatest potential to address water storage/ yield. Investing in Conservation: Enabling farmers, ranchers and other private land managers to successfully address the four resource priorities will require: • The adoption of conservation on 350,000 acres of private farmland, range, and forests, • Financial resources estimated at $ 200 million for installation and another $ 27 million annually to operate, and • Twenty or more years to complete with the current financial and technical resources available.

Based on research completed by NRCS planning staff, the greatest potential to reduce water demand exists by implementing irrigation and riparian/ wetland conservation practices in the Sprague Subbasin. This is followed by implementing agronomic and irrigation conservation practices in Tulelake. There is no measurable water demand benefit achieved by implementing conservation practices in the Upper Klamath River East Subbasin. Comparative Benefit: Water Quality The chart at left provides an overview of the comparative benefit by subbasin of various conservation practices that improve water quality. Based on research completed by NRCS planning staff, the greatest potential to improve water quality occurs when riparian/ wetland, grazing and irrigation conservation practices are implemented in the Sprague Subbasin. In comparison, no measurable water quality benefits are achieved by implementing conservation practices in Butte Valley or the Upper Klamath River East subbasins.

Based on research completed by NRCS planning staff, the greatest potential to enhance water storage and yield occurs by implementing riparian/ wetland, forest and range conservation practices in the Upper Klamath Lake Subbasin. In comparison, the Tulelake Subbasin gains water yield through agronomic practices like subsurface drains to allow for winter irrigation. Overall, implementing forest and range practices in most subbasins will result in greater water yield within the soil profile and water table. Comparative Benefit: Habitat/ Fish Survival The chart at right provides an overview of the comparative benefit by subbasin of various conservation practices that improve wildlife habitat and fish survival. Based on research completed by NRCS planning staff, the greatest potential to improve habitat is in the Sprague Subbasin, using wetland/ riparian, forest, range and irrigation practices. In comparison, no measurable habitat benefits are achieved by implementing additional conservation practices in the Middle Lost River, Tulelake, Butte Valley or Upper Klamath River subbasins. Conservation in the Upper Klamath Basin 17 Tim McCabe/ NRCS 18 The Sprague River Subbasin is located 25 miles northeast of Klamath Falls and covers approximately 1.02 million acres. Forested mountain ridges enclose the Sprague River Valley, which includes large marshes, meadows and irrigated pasture. Juniper and sagebrush steppes dominate rangeland. Irrigated Pasture is the predominant land use in the Sprague River Valley. Approximately 65 percent of the water used for irrigation is diverted from streams, and 35 percent is pumped from wells. Flooding is the most common form of irrigation. Most diversions do not have fish screens and lack devices to measure water deliveries. Overall irrigation application efficiencies are low. Private forest and rangelands in the Sprague River subbasin are generally used for livestock grazing. Most forest stands are significantly overstocked with trees, and rangeland has been heavily encroached by Western Juniper. Pasture condition is generally poor to fair. The riparian areas within pastures have little to no riparian vegetation and high, eroding banks. Wildlife habitat in most of the upper reaches of the Sprague River and its major tributaries appears to be fairly stable, indicating good watershed condition. However, there are considerable habitat improvements that can be made in the lower portion of the basin. Sprague River Subbasin Water & Wetlands: 2,949 Range: 137,869 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 240,050 Sprague River Subbasin Agricultural Land Use/ Cover 19 Resource Concerns Water quality is the major resource concern in the Sprague River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. Lost River and shortnose suckers, interior redband and bull trout are key fish species present in the subbasin. All species are listed as Endangered Species Act threatened, candidate, or species of concern. The Sprague River has been identified as an important stream for both spawning and rearing habitat for suckers. Loss of riparian habitat, fish entrapment and fish migration impediments have also been identified as resource concerns in the Sprague River Subbasin. Conservation Accomplishments In the Sprague River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved the condition of 2,153 acres of grazing land, improved irrigation water management on 903 acres of irrigated land, and have restored 1,644 acres of riparian and wetlands areas. Fencing and riparian area restoration has been initiated or installed by private land managers with assistance from NRCS, US Fish & Wildlife Service and others on approximately 50 miles of stream and several thousand additional riparian and wetland acres. Sprague River Subbasin Land Ownership Private Lands 448,200 Public Lands 573,100 Total Land Area: 1,021,300 Irrigated Acres USBR Project: 0 Non- USBR: 61,600 Total: 61,600 20 Conservation Opportunities Water Quality & Wildlife Habitat: Riparian restoration can be accomplished by converting pastures to permanent riparian wildlife lands or establishing riparian vegetation. Riparian pasture units should be managed as a part of an overall grazing plan with cross- fencing and off- stream water for livestock. Forest stands should be managed to ensure optimum health of both the trees and grazed understory. Thinning overstocked trees and controlling juniper on rangelands are both effective management opportunities. Water Demand: Irrigation water management, including measuring water use and scheduling irrigation will help managers to maintain base river flows through late summer and early fall. Efficiencies can also be gained by leveling land, lining or piping irrigation ditches and incorporating tailwater recovery systems. Conversion from flood to sprinkler irrigation is also beneficial.

Combined, the Williamson and Sprague River subbasins make up 79 percent of the lake’s total drainage area. The Winema National Forest and Klamath Falls National Wildlife Refuge account for most of the public land in the subbasin. Irrigated pasture is the dominant private agricultural land use. Pasture is almost entirely flood irrigated. Ninety percent is diverted from streams, while groundwater supplies ten percent. Most diversions do not have fish screens and lack devices to measure water deliveries. Although overall irrigation application efficiency is low, additional water in the water table helps to subirrigate pastures. In addition, the proximity of these pastures to rivers and streams allows most excess diverted water to return to the system for reuse. Private forest and rangelands make up most of the private land in the basin. Approximately 80 percent of forestlands are used for grazing. Private forestland is in poor to fair condition; over half of the stands are significantly overstocked with trees. Wildlife habitat has faced considerable degradation in the past. Of the 48 miles of stream that are degraded in the subbasin, restoration efforts have been initiated on approximately 23 miles. Williamson River Subbasin Water & Wetlands: 19,700 Range: 2,600 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 225,300 Williamson River Subbasin Agricultural Land Use/ Cover Irrigated Alfalfa: 1,100 23 Water quality relating to elevated stream temperatures is a major resource concern in the Williamson River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. In 1988, when the Lost River and Shortnose suckers were listed as endangered, the Williamson and Sprague River runs were estimated to have declined by as much as 95 percent during the previous twenty- year period. Important sucker habitat has diminished by nearly 50 percent in the lower reaches and near the mouth of the Williamson River. This has reduced the amount of larval sucker spawning and rearing habitat. Conservation Accomplishments Significant conservation progress has been made in this subbasin. Land managers have improved 500 acres of grazing lands, 1,000 acres of irrigated lands, 235 acres of forestlands and have restored 112 acres of riparian and wetland areas. Heightened landowner awareness of resource concerns and increasing agency, organization, and individual efforts will help this trend to continue. Of the 48 miles of stream that are degraded in the subbasin, private land managers are working with the US Fish and Wildlife Service and others to restore 23 miles. The Nature Conservancy is restoring approximately 3,200 acres of wetlands, and plans to restore another 3,411 acres at the mouth of the Williamson River.

This can be accomplished by converting lands from irrigated agriculture to wildlife habitat or creating riparian pasture systems. Wetland and riparian areas still utilize water. However, this work may reduce total water demand depending on how lands are managed. Water Demand: Thinning forest stands and managing grazing areas by adding cross fences and off- stream water for livestock can yield more water to meet downstream needs. This will also result in enhanced wildlife habitat and improved water quality in area streams. In addition, forest stand improvements reduce the potential for catastrophic fire.

Historically, some 43,000 acres of wetlands surrounded Agency and Upper Klamath Lake. Today, 17,000 acres have been preserved as part of the Upper Klamath Lake National Wildlife Refuge. Another 11,000 acres have been acquired for restoration. Irrigated agriculture is primarily pasture. Livestock are generally stocker cattle, who graze between April and November. Pasture condition is generally fair. Most livestock obtain water from streams and ditches. Irrigation water is diverted from streams or pumped from the lake. Most diversions do not have fish screens or devices to measure water. Although overall irrigation application efficiency is low, the additional water raises the water table and subirrigated pastures. Some acreages of hay and cereal crops are grown, and irrigation efficiencies are higher than for pasture. However, most require maintenance and re- leveling. Forestlands are primarily pine and mixed fir and hemlock. Most private lands in the subbasin are forest or rangelands, with approximately 80 percent used for grazing. More than half of the forest stands are significantly overstocked with trees. Wildlife habitat varies in condition. Of 70 total miles, 21 miles of streamside riparian areas are in good condition and another 12 miles are being restored. Upper Klamath Lake Subbasin Water & Wetlands: 76,568 Range: 2,404 Irrigated Pasture/ Grass Hay: 48,856 Forest/ Mixed: 100,311 Upper Klamath Lake Subbasin Agricultural Land Use/ Cover Irrigated Crop/ Alfalfa: 3,396 27 Resource Concerns Water quality in the Upper Klamath Lake is a major resource concern, affecting subbasin fish survival, with phosphorus loading as the greatest factor. The loss of wetland vegetation around the lake has also been linked to lower survival rates for endangered suckers. The lower reaches of the Wood River and Sevenmile Creek provide some rearing habitat for larval and juvenile suckers. The Wood River, Sevenmile Creek and their tributaries support populations of bull and interior redband trout. A highly valued “ catch and release” sport fishery occurs on the Wood River and several of its tributaries. There is significant interest in enhancing riparian habitat along these streams to protect and promote these fisheries. Conservation Accomplishments In the Upper Klamath Lake Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved 12 acres of grazing lands and improved water quality and quantity on 12 acres of irrigated land. Several thousand more acres of wetland restoration are in the process of being planned or implemented around Upper Klamath Lake.

This can be accomplished by either converting pastures to permanent wildlife habitat or by creating riparian pastures. While most pastures are being inefficiently irrigated, conditions do not warrant extensive changes from current flood irrigation systems since water is reused or enters the soil profile Water Storage: In the Upper Klamath Lake Subbasin, the potential for non- traditional water storage presents a unique conservation opportunity. Restoring drained wetlands, still farmed around Upper Klamath Lake, could produce positive benefits for all four resource concerns. By actively managing areas for both seasonal wetlands and farming, water can be both filtered to improve water quality and stored in wetland areas for future use.

The valley once supported a vast network of wet meadows and marshes. This subbasin covers approximately 1.2 million acres and is split from the Middle Lost River Subbasin near Olene. Irrigated agriculture generally occurs in the warmer valleys. Flood is the most common pasture irrigation method, with about 50 percent of the water coming from the USBR project. Pasture condition is fair, and most pastures have not been renovated or re- leveled for some time. Maintenance would increase the efficiencies of 60 to 80 percent of the systems. Alfalfa is customarily sprinkler- irrigated and well- managed. Although irrigation efficiencies are higher than for pasture, many sprinkler systems still need upgrading. Several irrigated crops are grown in the subbasin including cereal grains, potatoes, and strawberry plants. Forestland, range and pasture are grazed by livestock. Rangelands are comprised of juniper and sagebrush steppes. Forestlands are generally mixed conifer. Livestock operations include cow/ calf, stockers and dairies. Confined livestock operations are located throughout the subbasin. The location and duration of confinement may pose a potential risk to water quality. Seven dairies located within the subbasin have existing liquid and dry livestock waste storage facilities.

High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving over the last 10 to 20 years. While agriculture is the dominant land use in this subbasin, other sources of phosphorus and other pollutants exist. Sewage treatment outfalls, on- site sewage disposal systems, wildlife, and natural inputs also contribute nutrients and other pollutants to the system. While historically the river had significant fish runs, it currently supports only a small population of Shortnose and Lost River suckers. Conservation Accomplishments In the Upper Lost River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved resource conditions on 234 acres of croplands and 5,282 acres of grazing lands, and have improved their management of irrigation water on 5,596 acres of irrigated lands. In addition, 846 acres of riparian and wetland areas have been restored.

On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops. Implementing practices like diverting clean water before it flows through livestock confinement areas near water sources, will reduce the risk of polluted runoff. Water Demand: On both surface-irrigated pastures and cropland areas, there are opportunities for land leveling or smoothing, lining or piping irrigation delivery ditches, upgrading irrigation systems and developing tailwater recovery systems to improve water use efficiency.

Farms near Klamath Falls tend to be smaller, indicating part- time or hobby operations. The area includes 12 irrigation districts and leased lands on the Lower Klamath Wildlife Refuge that receive water supplied by the USBR Klamath Project. Public lands include the refuge, and parts of Modoc and Klamath national forests. Irrigated agriculture includes pasture, alfalfa, cereal grain, potatoes, onions and mint. Roughly 70 percent is irrigated with USBR- supplied water; the rest is obtained from groundwater, individual surface water rights or special USBR contracts. Many fields are either flood or sprinkler irrigated depending on the year and crop. Most farm irrigation diversions lack a means to measure water delivery. Livestock operations include several dairies and cattle feeding operations. Substantial range acreage is used for livestock grazing. Pasture condition is fair and most pastures have not been renovated or re- leveled for some time. Pastures associated with smaller livestock operations in and around Klamath Falls appear to be in the most need of improved pastures and irrigation systems. Wildlife habitat: Ten river miles are in relatively good riparian condition given the river is used for conveying irrigation water. Some 13 miles of stream lack adequate riparian vegetation and streambank protection.

Drought conditions and increased competition for available water have increased economic, social, political and environmental concerns and uncertainty over the future. Habitat and water quality are two additional major resource concerns in the subbasin. High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other pollutant sources exist. While the river had significant historic fish runs, it currently supports only a small sucker population. Conservation Accomplishments In the last two years, the Middle Lost River Subbasin has seen significant conservation progress. With assistance from NRCS and local conservation districts, land managers have improved the condition of natural resources on 489 acres of cropland and 3,521 grazing land acres. In addition, 564 acres of riparian and wetland areas have been restored, and water use efficiency has been increased on 3,731 acres of irrigated lands.

Highly effective conservation measures on hay and cropland should focus on updating existing irrigation systems and improving irrigation water management. Water Quality: The use of grazing systems that rotate livestock through smaller pastures will increase forage production, reduce soil compaction and improve water quality. While fishery benefits from restoring riparian areas are minimal, streamside buffers will improve water quality and provide habitat for other wildlife. On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops.

The Tulelake Irrigation District and the Tulelake National Wildlife Refuge receive water from the USBR Klamath Project. Tulelake is a remnant of historic Lake Modoc that once connected the subbasin with both Lower and Upper Klamath Lake. The Lost River watershed was once a closed basin. Runoff flowed into Tulelake and evaporated. Pumping plants and drains constructed as a part of the project have provided an outlet from Tulelake, which now functions as an open basin. Irrigated agriculture is generally supplied by the USBR. Alfalfa, grain, potatoes, onions, mint and pasture are the principal crops. Fields are flood or sprinkler irrigated depending on the year and crop. Often diversions lack devices to measure water delivery. Pasture condition is fair, and most have not been renovated for some time. Groundwater provides 40- 50 percent of water for irrigated pastures, and most excess water is reused. Rangeland is the other significant land use. Most ranches are cow/ calf operations that have winter holdings in the subbasin. Rangelands are generally encroached with juniper. Wildlife habitat along the Lost River has reeds and bullrush, providing some habitat for waterfowl and songbirds. Suckers have been located in the river and Tulelake; however, it is not known whether they are successfully reproducing. There are few opportunities to improve habitat along this heavily manipulated reach of the river.

Irrigators depend on water- use decisions made by fellow irrigators and resource managers for their irrigation needs. Drought and increased competition for water leads to the primary resource concern in the basin - a reliable supply of water to meet agriculture, wildlife and other resource needs. Water quality deteriorates as it moves through the USBR project. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other sources of phosphorus and other pollutants exist. The presence of ESA- listed suckers creates concerns for improving habitat and water quality. The two national wildlife refuges support large waterfowl populations. Farmland on the refuges is leased to farmers to supply grain for waterfowl and shorebirds. These populations depend on refuges, leased lands and adjacent farms during the fall and spring migratory periods. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Tulelake Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, local land managers have improved the condition of natural resources on 72 cropland acres and 1,854 irrigated land acres, and have restored 21 acres of riparian and wetland areas.

Subsurface drainage could be added before re- establishing alfalfa stands, permitting better control of water table and soil moisture levels. During years that alfalfa fields are rotated to grain, winter flooding or pre- season irrigation could be used to reduce water demand. Water Storage/ Yield: Adding subsurface drainage may be the most significant practice to implement on cropland acres. Subsurface drains would allow farmers to winter flood or pre-irrigate fields, thereby reducing their demand for water during the irrigation season. If pre- irrigated, farmers could grow a cereal crop even if water deliveries are cut off during drought years. In addition, juniper control on rangelands will yield additional water to meet downstream needs.

While part of the Upper Klamath Basin, it is an internal drainage basin with only an artificial outlet. Groundwater flows from west to east out of the subbasin under the Mahogany Mountains toward the lake. A channel and pump plant were built to remove floodwaters. This channel is used infrequently and for only short durations. The Klamath National Forest, Butte Valley National Grassland, and the Butte Valley Wildlife Area make up the majority of the public lands. Irrigated agriculture includes alfalfa hay as the predominate crop. Cereal grains, potatoes and strawberry plants are also grown. Crops are usually sprinkler irrigated, and sprinklers are well maintained. Few irrigators measure water applied or schedule irrigation. Cattle operations graze irrigated pastures and meadows scattered throughout the subbasin along with range and forestlands. Pastures are generally flood irrigated and are supplied by streams. Most farm irrigation diversions lack water measuring devices. Mixed conifer forests are found at higher elevations and are generally operated as industrial forests. Range sites are dominated by Western Juniper and are generally in poor condition. Wildlife habitat is generally wetlands in the state wildlife refuge or on national grasslands. Approximately 26 miles of streams on private lands have inadequate riparian vegetation.

Generally, streams in the upper portions of the subbasin support good populations of Brown and Rainbow trout. The Tulelake National Wildlife Refuge and Lower Klamath Lake National Wildlife Refuge support large populations of migratory and permanent waterfowl. Farmland on the refuges is leased to area farmers to supply grain for the waterfowl and shorebirds. The large bird populations depend on the refuges, leased lands and adjacent farms throughout the fall and spring migratory periods for habitat. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Butte Valley Subbasin during the last two years, some conservation progress has been made.

Other than limited contributions to groundwater in the Upper Klamath Basin, reductions in water demand only benefit the subbasin. Sprinkler- irrigated hay, cereal crops and row crops dominate land use on the better soils. Highly effective conservation on hay and cropland should focus on improving the overall irrigation efficiency of existing systems. This can be accomplished by upgrading systems and scheduling irrigation. An estimated 40 percent of the existing systems would benefit from maintenance. On controlled flood irrigated pastures, there are opportunities for land leveling or smoothing, lining or piping delivery ditches, and recovering tailwater. Additional water savings and water quality benefits could be gained by converting existing surface irrigation to sprinklers if power is available and affordable. On rangelands, juniper control and improved grazing management are the primary conservation opportunities.

Nearly half of the area is in public ownership. Iron Gate and Copco reservoirs are used extensively for recreational fishing, boating and camping. Whitewater rafting and kayaking are popular below the KC Boyle Dam. The KC Boyle, Copco and Iron Gate dams are used and regulated for power generation. Irrigated agriculture occurs on only 4,000 acres of pasture. Only a few isolated ranches are located in this subbasin. Cattle operations rotate grazing of irrigated pastures with significant acreage of grazed range and forest. Pastures are surface irrigated with a mix of controlled and flood irrigation. All irrigation water is diverted from the river or tributary streams. Most farm irrigation diversions lack devices to measure water. Even though overall irrigation application efficiency is low, the proximity of irrigated pastures to the river allows most excess water diverted to be reused downstream. Private forest and rangelands make up most of the private land, nearly all of which is used for livestock grazing. Much of the rangeland is in poor condition, with heavy juniper encroachment. More than half of the forest stands are overstocked with trees. Wildlife habitat along riparian areas is generally in good condition. Of the 12 miles of riparian areas surveyed, five would benefit from some restoration.

Natural Resources Conservation Service Year: 2004, 2005 1 i California Oregon Cover Photo: Lower Klamath National Wildlife Refuge at sunset Tupper Ansel Blake/ USFWS Map Detail Area: Upper Klamath River Basin ii T he Klamath River Basin presents numerous challenges as well as opportunities for its many water users. For years, farmers and ranchers in the basin have recognized the vital role they play in the health of their watershed. Working with conservation districts, the Natural Resources Conservation Service ( NRCS) and others, land managers continue to proactively find ways to enhance natural resources in the basin, benefiting wildlife and the environment. However, as it has across the western United States, drought hit home in the Klamath for those who depend on every drop of water to sustain their livelihood, culture and community. In the spring of 2001, the combination of drought and the impact of the Endangered Species Act triggered a shutdown of irrigation water during the growing season, drying up water resources to more than 2,000 farms and ranches. NRCS, in cooperation with local conservation districts, provided a quick infusion of technical assistance and $ 2 million in cost- share funding for cover crops through the Emergency Watershed Protection Program. As cover crops took hold, the seeds of a long- term solution took root in the NRCS/ conservation district partnership. The ability of the local office to receive funding, engage community members and other partners, plan resource improvements, implement actions, and monitor success proved to be an invaluable asset for the community. Helping private landowners develop and apply practical, common- sense solutions to complex resource issues will be the challenge of the conservation partnership well into the future. USDA, in concert with the locally led conservation districts, will continue to play a critical role by delivering technical and financial assistance to Klamath Basin farmers and ranchers. The Rapid Subbasin Assessments that follow are the first step in that process. The assessments are designed to help local decision- makers determine where investments in conservation will best benefit wildlife habitat, agriculture and other land uses in a compatible manner. It is our goal to provide a comprehensive overview of resource challenges and opportunities in the basin, and help decision- makers to prioritize their investments in areas that will best sustain multiple use of natural resources in the basin now and in the future.

Stretching across southern Oregon and northern California, the Klamath Basin has become synonymous with the water challenges that western water users face. As one example, agricultural commodities that need irrigation water to thrive – providing Americans with the cheapest domestic food supply in the world, face competition from the critical water needs of sucker fish, salmon and other threatened and endangered species. While that competition is understandable, more and more, conservation leaders in all industries have come to recognize that these water needs aren’t necessarily at odds with one another, and can in fact be compatible. While an example of the challenges today’s agricultural producers and conservationists face, the Klamath Basin has emerged as an example of how diverse interests can work together successfully. 2 Overview of the Upper Klamath Basin Upper Klamath Basin Description The Upper Klamath Basin is an area of high desert, wetlands, and the Klamath River. The river extends 250 miles from its headwaters at Upper Klamath Lake in south central Oregon to the west coast of northern California. The Upper Klamath Basin includes the US Bureau of Reclamation’s ( USBR) Klamath Project Area and the drainage area above Irongate Dam on the Klamath River. The basin’s lakes, marshes, and wetlands host an abundance of plant and animal species and include national wildlife refuges, parks, and forests. Agricultural production began around the turn of the 20th century, and with the creation of the Klamath Irrigation District in 1905, water diversions for irrigation began in earnest. A portion of these irrigated lands are in the USBR’s irrigation project. The ‘ project area,’ as it is commonly called, includes 188,000 of the 502,000 acres of private irrigated land in the basin. This includes lands leased from the various wildlife refuges that are supplied with water by the USBR. Privately irrigated acreages can vary from year to year, depending on USBR contracts and annual cropping cycles. In comparison, the majority of the private irrigated land - about 314,000 acres - in the basin is located outside the project area. Upper Klamath Basin Quick Facts: • Over 2.2 million acres are privately owned in the Upper Klamath Basin • 188,000 of the irrigated acres are in the US Bureau of Reclamation’s Irrigation Project • Approximately 502,000 acres of privately owned lands are irrigated • 314,000 acres of irrigated lands are outside the Project area 3 Overview of the Upper Klamath Basin The Role of Agriculture in the Basin Agricultural lands play a key role in a healthy ecosystem. Located on the Pacific Flyway, migratory birds like the American White Pelican and the Red- Necked Grebe use croplands in the Klamath Basin as an important feeding and resting stop. Deer graze on wheat and barley fields, and pheasants use both crop and rangelands for their nesting and feeding grounds. Progressive conservation leaders recognize that farming and fish and wildlife habitat are not mutually exclusive. Well- maintained farmland creates fish and wildlife habitat, contributing to a healthy watershed. They also recognize that opportunities will always exist to improve the condition of natural resources in the basin. To address those opportunities, conservation leaders in Oregon’s Klamath Falls Soil and Water Conservation District and California’s Lava Beds/ Butte Valley Resource Conservation District have proactively identified four key priorities tied to natural resource conservation. The districts asked experts at the USDA’s Natural Resources Conservation Service to help them develop a plan to determine what could be done on- farm to conserve water, increase water storage, improve water quality, and enhance fish and wildlife habitat. While so much of the attention to date in the Klamath Basin has been focused on water demand, these conservation leaders recognize demand is only one piece of the puzzle. Comprehensive solutions must also address water quality, storage and wildlife habitat. Conservation District Priorities 1) Conserve Water 2) Increase Water Storage 3) Improve Water Quality 4) Enhance Fish & Wildlife Habitat 4 Rapid Subbasin Assessments Conserving natural resources is the ultimate goal throughout the basin, and its success hinges on long- term solutions. At the request of local conservation districts, NRCS undertook an 18- month study of resource concerns, challenges and opportunities throughout the Upper Klamath Basin. The study was not intended to provide a detailed, quantitative analysis of the impacts of conservation work, but rather, to provide an initial estimate of where conservation investments would best address the districts’ four priority resource concerns. Beginning in the spring of 2002, NRCS planners collected information to enable the conservation districts, agencies, organizations, farmers, ranchers and others to make informed decisions in a timely manner about conservation and resource management in the basin. These Rapid Subbasin Assessments are intended to help leaders set priorities and determine the best actions to achieve their goals. As a part of the rapid subbasin assessment process, eight subbasins were delineated ( see map at left). A watershed planning team traveled through each subbasin, inventorying agricultural areas, identifying conservation opportunities and current levels of resource management, and estimating the impacts of these opportunities on the Conservation in the Upper Klamath Basin 5 Conservation in the Upper Klamath Basin conservation districts’ priority resource concerns. They focused their recommendations on areas that would provide the best benefit to the wide array of stakeholders in the Upper Klamath Basin. They also identified a number of socio- economic factors that must be taken into consideration when helping producers adapt to new management styles and conservation activities. Through NRCS, conservation districts and other federal, state and local entities, private land managers are working to identify ways they can more efficiently use – and share – the water they need. In the face of increasingly complex and politically polarized circumstances, a clear purpose and direction has arisen. The commitment of the local conservation partnership to identify the impacts of water shortages and to find solutions that will improve natural resource conservation will be key to the long- term viability of both endangered species and industries in the Upper Klamath Basin. The information that follows provides a summary of the conservation challenges and opportunities that NRCS staff found in their assessment. Recommendations for where financial and other resources can best be invested to improve natural resources, while sustaining the economy of the Upper Klamath Basin, are also identified. 6 Conservation in the Upper Klamath Basin Private Lands Conservation Accomplishments One component necessary to understanding future conservation opportunities in the basin is to recognize the current conservation work of private land managers. An indicator of these efforts is the work that has been undertaken in partnership with NRCS and the local conservation districts. In federal fiscal years 2002 and 2003, Upper Klamath Basin farmers and ranchers improved resource conditions on 18,877 acres of privately owned agricultural lands, with assistance from NRCS and the conservation districts. During this time, private land managers have worked with the conservation districts in the basin to: • improve the condition of 11,800 acres of grazing lands • conserve water and improve water quality on 13,656 acres • restore and establish 4,138 acres of wetlands and riparian areas • improve 281 acres of forest stands • establish resource management systems on 1,351 acres of cropland These conservation efforts were accomplished with a combination of private, state and federal funding. 7 Conservation in the Upper Klamath Basin Summary of Conservation Opportunities In addition to recognizing current conservation activities, the assessments define what can be accomplished with a strong conservation partnership in the Upper Klamath Basin. All too often, the debate about multi- use of water in the basin has focused on ways to reduce water demand. However, the basin’s many water users - including fish and wildlife - benefit just as much from improvements to water quality, water storage and wildlife habitat. Taken together, the recommendations that follow seek to utilize a comprehensive approach to all four resource priorities - with the goal of contributing to a sustainable, multi- use water system. While quantification of the results of conservation work in these four areas is difficult, there is no question that a comprehensive approach to natural resource improvement in the Upper Klamath Basin will result in accumulative long- term benefits for endangered fish species, wildlife habitat, agriculture, urban and other water uses. Agriculture cannot undertake these efforts alone. Private landowners and the general public both benefit from natural resources conservation in the Upper Klamath Basin. Because of this, public and private sources of funding from in and outside the region are necessary. Solutions of this magnitude also come with other social, political, and cultural costs. Upper Klamath Basin Quick Facts: • 1,400 farm families live in the Upper Klamath Basin • The Upper Klamath Basin is home to sucker fish, bull trout and redband trout 8 Conservation in the Upper Klamath Basin For example, all stakeholders in the Upper Klamath Basin need to identify and address social, economic, and cultural resource- based values they have historically enjoyed. Politically, there must be resolution and agreement on water rights, endangered species, and water quality. Water Conservation Because few water use measurements have been taken in the past, it is difficult to quantify where specific water efficiencies can be gained. Throughout the Upper Klamath Basin, water that leaves one irrigated field generally re- enters streams or enters the groundwater, providing the opportunity for it to be utilized again later. Because of this, water delivery systems both in and outside the USBR project area are generally efficient. As a result, the most significant benefit of reducing water demand on individual farms is an improvement in water quality and reduction in water temperatures, rather than an increase in available water. 9 Conservation in the Upper Klamath Basin Conservation measures that reduce water demand on private agricultural lands can be accomplished in a variety of ways. New technologies for managing when and where water is applied on crop and pasture lands will help to ensure that water is only applied when it is of the best benefit to the plant. Water conservation opportunities include improving irrigation water-use efficiency, retaining and conserving drainage water, and making use of new technologies that more accurately forecast the impacts of drought and floods. The subbasin assessments indicate an opportunity to conserve water and improve water quality on 130,000 acres of irrigated lands within the USBR project. Outside the project area there is an opportunity for water conservation on approximately 220,000 irrigated acres. If all potential conservation practices are implemented on all irrigated lands, on- farm water use efficiency could increase by up to 25 percent in the Upper Klamath Basin. A potential two to five percent increase in water yield could be achieved by increasing management in upland range and forestland areas. In all cases, these are preliminary estimates and require validation. This estimate does not account for evaporation, transpiration, seepage or other loses that may occur at the sites receiving conserved water nor does it evaluate irrigation delivery or conveyance efficiencies. Tupper Ansel Blake/ USFWS 10 Conservation in the Upper Klamath Basin This level of water conservation cannot be reached without a concerted federal/ state/ private partnership that works together to apply water conservation practices in targeted areas throughout the Upper Klamath Basin. Improving Water Quality Water quality has a direct impact on many fish and wildlife species. Within the Upper Klamath Basin, most rivers and lakes do not meet federally mandated Clean Water Act standards for temperature, dissolved oxygen, pH, or other pollutants. Water quality is affected by water temperature, low in- stream flows and the condition of adjacent land riparian areas, among other items. Private landowners are just one of many groups who have an opportunity to improve water quality throughout the basin. Water quality improvement opportunities on private agricultural lands in the basin range from improving the management of livestock near streams and rivers to utilizing new technologies that track pest and weed cycles to ensure that pesticides are only applied when they will be most effective. Water conservation practices that reduce tailwater runoff from irrigated fields can provide extensive improvements in water quality. 11 Conservation in the Upper Klamath Basin Increasing Water Storage/ Yield In recent years, drought has been a large contributing factor to reduced water levels in the Upper Klamath Basin. One solution to address low water flows would be to store water for times of water shortage. There are at least two challenges to this solution: finding a place to store water and finding water to store. To evaluate this option, potential storage values were calculated for 41 years of record from 1961 to 2002. This analysis reinforced the observation that, as has been seen in recent years, drought years normally occur in a multi- year cycle. Because of this, in the years where extra water is most needed, it is often not available from previous years to store. One promising, small- scale, water storage solution may lie in subsurface irrigation water storage in suitable locations, such as the Tulelake Subbasin. In this scenario, there exists a potential to store water in the soil profile and reduce irrigation water demand during the irrigation season. Another option for subsurface storage of water includes the restoration of streams and their surrounding wetlands and riparian areas. This can increase the “ sponge” effect allowing for the slow release of water through the long, dry summer months. Tupper Ansel Blake/ USFWS 12 Conservation in the Upper Klamath Basin Enhancing Fish and Wildlife Habitat The Upper Klamath Basin is home to a wide variety of aquatic and terrestrial species of wildlife and fish. Much of the water used in the Klamath wildlife refuges and associated marshes, ponds, streams and wetlands originates in the Upper Klamath Lake Subbasin. The Klamath Basin wildlife refuges provide a stopover for 85 percent of the ducks, geese, and other birds that migrate through the Pacific Flyway from Alaska to South America. Streams in the Upper Klamath Basin provide spawning and rearing habitat to threatened and endangered suckers and bull trout, as well as redband trout, which is listed as a species of concern by the US Fish and Wildlife Service. Several streams are highly valued “ catch and release” sport fisheries. There is high landowner and public interest in restoring and maintaining riparian habitat along these streams. Many of the conservation opportunities outlined under water conservation and water quality provide direct benefits to fish and wildlife as well. In addition, creating and restoring wetland areas, planting trees and developing wildlife habitat along the edges of crop fields all contribute to enhancing wildlife habitat in the basin. Tupper Ansel Blake/ USFWS 13 Conservation in the Upper Klamath Basin Overview of Conservation Effectiveness In order for the Upper Klamath Basin to successfully move forward with solutions, agriculturists, environmentalists, Tribes, government agencies, organizations, and others need to develop unified leadership to arrive at a common vision for the future. In addition, stakeholders and others must commit to a long- term investment of public and private funding as well as other resources. Based on the Upper Klamath Basin Rapid Subbasin Assessments, the Oregon and California NRCS planning staff rated the potential benefit of recommended conservation practices and resource management systems based on the conservation districts’ four resource priorities. Many state and federal agencies have invested in conservation work throughout the basin. While the recommendations in this document focus on private land and agriculture, the assessments can also be applied to help prioritize conservation practices on other land uses basin- wide. Overall, based on the planning team’s analysis, conservation activities in the Sprague River Subbasin would produce the greatest benefit, and conservation practices in the Upper Klamath River East Subbasin would yield the least Tupper Ansel Blake/ USFWS overall benefit based on the conservation district’s priorities. 14 Conservation in the Upper Klamath Basin While recognizing that any science- based conservation focus in the Upper Klamath Basin would be beneficial, the charts on pages 18- 19 specifically focus on work that can be accomplished on private lands. They provide a breakdown of recommended conservation practices on each of the conservation districts’ priorities by subbasin. For example, the water demand chart shows that investing in conservation practices in the Sprague River Subbasin has the greatest potential for reducing agriculture’s water demand by implementing improved irrigation practices. The Sprague also provides the best opportunity to address water quality and wildlife habitat. Investment in conservation activities in the Tulelake and the Upper Klamath Lake subbasins offers the greatest potential to address water storage/ yield. Investing in Conservation: Enabling farmers, ranchers and other private land managers to successfully address the four resource priorities will require: • The adoption of conservation on 350,000 acres of private farmland, range, and forests, • Financial resources estimated at $ 200 million for installation and another $ 27 million annually to operate, and • Twenty or more years to complete with the current financial and technical resources available.

This is followed by implementing agronomic and irrigation conservation practices in Tulelake. There is no measurable water demand benefit achieved by implementing conservation practices in the Upper Klamath River East Subbasin. Comparative Benefit: Water Quality The chart at left provides an overview of the comparative benefit by subbasin of various conservation practices that improve water quality. Based on research completed by NRCS planning staff, the greatest potential to improve water quality occurs when riparian/ wetland, grazing and irrigation conservation practices are implemented in the Sprague Subbasin. In comparison, no measurable water quality benefits are achieved by implementing conservation practices in Butte Valley or the Upper Klamath River East subbasins.

Based on research completed by NRCS planning staff, the greatest potential to enhance water storage and yield occurs by implementing riparian/ wetland, forest and range conservation practices in the Upper Klamath Lake Subbasin. In comparison, the Tulelake Subbasin gains water yield through agronomic practices like subsurface drains to allow for winter irrigation. Overall, implementing forest and range practices in most subbasins will result in greater water yield within the soil profile and water table. Comparative Benefit: Habitat/ Fish Survival The chart at right provides an overview of the comparative benefit by subbasin of various conservation practices that improve wildlife habitat and fish survival. Based on research completed by NRCS planning staff, the greatest potential to improve habitat is in the Sprague Subbasin, using wetland/ riparian, forest, range and irrigation practices. In comparison, no measurable habitat benefits are achieved by implementing additional conservation practices in the Middle Lost River, Tulelake, Butte Valley or Upper Klamath River subbasins. Conservation in the Upper Klamath Basin 17 Tim McCabe/ NRCS 18 The Sprague River Subbasin is located 25 miles northeast of Klamath Falls and covers approximately 1.02 million acres. Forested mountain ridges enclose the Sprague River Valley, which includes large marshes, meadows and irrigated pasture. Juniper and sagebrush steppes dominate rangeland. Irrigated Pasture is the predominant land use in the Sprague River Valley. Approximately 65 percent of the water used for irrigation is diverted from streams, and 35 percent is pumped from wells. Flooding is the most common form of irrigation. Most diversions do not have fish screens and lack devices to measure water deliveries. Overall irrigation application efficiencies are low. Private forest and rangelands in the Sprague River subbasin are generally used for livestock grazing. Most forest stands are significantly overstocked with trees, and rangeland has been heavily encroached by Western Juniper. Pasture condition is generally poor to fair. The riparian areas within pastures have little to no riparian vegetation and high, eroding banks. Wildlife habitat in most of the upper reaches of the Sprague River and its major tributaries appears to be fairly stable, indicating good watershed condition. However, there are considerable habitat improvements that can be made in the lower portion of the basin. Sprague River Subbasin Water & Wetlands: 2,949 Range: 137,869 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 240,050 Sprague River Subbasin Agricultural Land Use/ Cover 19 Resource Concerns Water quality is the major resource concern in the Sprague River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. Lost River and shortnose suckers, interior redband and bull trout are key fish species present in the subbasin. All species are listed as Endangered Species Act threatened, candidate, or species of concern. The Sprague River has been identified as an important stream for both spawning and rearing habitat for suckers. Loss of riparian habitat, fish entrapment and fish migration impediments have also been identified as resource concerns in the Sprague River Subbasin. Conservation Accomplishments In the Sprague River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved the condition of 2,153 acres of grazing land, improved irrigation water management on 903 acres of irrigated land, and have restored 1,644 acres of riparian and wetlands areas. Fencing and riparian area restoration has been initiated or installed by private land managers with assistance from NRCS, US Fish & Wildlife Service and others on approximately 50 miles of stream and several thousand additional riparian and wetland acres. Sprague River Subbasin Land Ownership Private Lands 448,200 Public Lands 573,100 Total Land Area: 1,021,300 Irrigated Acres USBR Project: 0 Non- USBR: 61,600 Total: 61,600 20 Conservation Opportunities Water Quality & Wildlife Habitat: Riparian restoration can be accomplished by converting pastures to permanent riparian wildlife lands or establishing riparian vegetation. Riparian pasture units should be managed as a part of an overall grazing plan with cross- fencing and off- stream water for livestock. Forest stands should be managed to ensure optimum health of both the trees and grazed understory. Thinning overstocked trees and controlling juniper on rangelands are both effective management opportunities. Water Demand: Irrigation water management, including measuring water use and scheduling irrigation will help managers to maintain base river flows through late summer and early fall. Efficiencies can also be gained by leveling land, lining or piping irrigation ditches and incorporating tailwater recovery systems. Conversion from flood to sprinkler irrigation is also beneficial.

Combined, the Williamson and Sprague River subbasins make up 79 percent of the lake’s total drainage area. The Winema National Forest and Klamath Falls National Wildlife Refuge account for most of the public land in the subbasin. Irrigated pasture is the dominant private agricultural land use. Pasture is almost entirely flood irrigated. Ninety percent is diverted from streams, while groundwater supplies ten percent. Most diversions do not have fish screens and lack devices to measure water deliveries. Although overall irrigation application efficiency is low, additional water in the water table helps to subirrigate pastures. In addition, the proximity of these pastures to rivers and streams allows most excess diverted water to return to the system for reuse. Private forest and rangelands make up most of the private land in the basin. Approximately 80 percent of forestlands are used for grazing. Private forestland is in poor to fair condition; over half of the stands are significantly overstocked with trees. Wildlife habitat has faced considerable degradation in the past. Of the 48 miles of stream that are degraded in the subbasin, restoration efforts have been initiated on approximately 23 miles. Williamson River Subbasin Water & Wetlands: 19,700 Range: 2,600 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 225,300 Williamson River Subbasin Agricultural Land Use/ Cover Irrigated Alfalfa: 1,100 23 Water quality relating to elevated stream temperatures is a major resource concern in the Williamson River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. In 1988, when the Lost River and Shortnose suckers were listed as endangered, the Williamson and Sprague River runs were estimated to have declined by as much as 95 percent during the previous twenty- year period. Important sucker habitat has diminished by nearly 50 percent in the lower reaches and near the mouth of the Williamson River. This has reduced the amount of larval sucker spawning and rearing habitat. Conservation Accomplishments Significant conservation progress has been made in this subbasin. Land managers have improved 500 acres of grazing lands, 1,000 acres of irrigated lands, 235 acres of forestlands and have restored 112 acres of riparian and wetland areas. Heightened landowner awareness of resource concerns and increasing agency, organization, and individual efforts will help this trend to continue. Of the 48 miles of stream that are degraded in the subbasin, private land managers are working with the US Fish and Wildlife Service and others to restore 23 miles. The Nature Conservancy is restoring approximately 3,200 acres of wetlands, and plans to restore another 3,411 acres at the mouth of the Williamson River.

This can be accomplished by converting lands from irrigated agriculture to wildlife habitat or creating riparian pasture systems. Wetland and riparian areas still utilize water. However, this work may reduce total water demand depending on how lands are managed. Water Demand: Thinning forest stands and managing grazing areas by adding cross fences and off- stream water for livestock can yield more water to meet downstream needs. This will also result in enhanced wildlife habitat and improved water quality in area streams. In addition, forest stand improvements reduce the potential for catastrophic fire.

Historically, some 43,000 acres of wetlands surrounded Agency and Upper Klamath Lake. Today, 17,000 acres have been preserved as part of the Upper Klamath Lake National Wildlife Refuge. Another 11,000 acres have been acquired for restoration. Irrigated agriculture is primarily pasture. Livestock are generally stocker cattle, who graze between April and November. Pasture condition is generally fair. Most livestock obtain water from streams and ditches. Irrigation water is diverted from streams or pumped from the lake. Most diversions do not have fish screens or devices to measure water. Although overall irrigation application efficiency is low, the additional water raises the water table and subirrigated pastures. Some acreages of hay and cereal crops are grown, and irrigation efficiencies are higher than for pasture. However, most require maintenance and re- leveling. Forestlands are primarily pine and mixed fir and hemlock. Most private lands in the subbasin are forest or rangelands, with approximately 80 percent used for grazing. More than half of the forest stands are significantly overstocked with trees. Wildlife habitat varies in condition. Of 70 total miles, 21 miles of streamside riparian areas are in good condition and another 12 miles are being restored. Upper Klamath Lake Subbasin Water & Wetlands: 76,568 Range: 2,404 Irrigated Pasture/ Grass Hay: 48,856 Forest/ Mixed: 100,311 Upper Klamath Lake Subbasin Agricultural Land Use/ Cover Irrigated Crop/ Alfalfa: 3,396 27 Resource Concerns Water quality in the Upper Klamath Lake is a major resource concern, affecting subbasin fish survival, with phosphorus loading as the greatest factor. The loss of wetland vegetation around the lake has also been linked to lower survival rates for endangered suckers. The lower reaches of the Wood River and Sevenmile Creek provide some rearing habitat for larval and juvenile suckers. The Wood River, Sevenmile Creek and their tributaries support populations of bull and interior redband trout. A highly valued “ catch and release” sport fishery occurs on the Wood River and several of its tributaries. There is significant interest in enhancing riparian habitat along these streams to protect and promote these fisheries. Conservation Accomplishments In the Upper Klamath Lake Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved 12 acres of grazing lands and improved water quality and quantity on 12 acres of irrigated land. Several thousand more acres of wetland restoration are in the process of being planned or implemented around Upper Klamath Lake.

This can be accomplished by either converting pastures to permanent wildlife habitat or by creating riparian pastures. While most pastures are being inefficiently irrigated, conditions do not warrant extensive changes from current flood irrigation systems since water is reused or enters the soil profile Water Storage: In the Upper Klamath Lake Subbasin, the potential for non- traditional water storage presents a unique conservation opportunity. Restoring drained wetlands, still farmed around Upper Klamath Lake, could produce positive benefits for all four resource concerns. By actively managing areas for both seasonal wetlands and farming, water can be both filtered to improve water quality and stored in wetland areas for future use.

The valley once supported a vast network of wet meadows and marshes. This subbasin covers approximately 1.2 million acres and is split from the Middle Lost River Subbasin near Olene. Irrigated agriculture generally occurs in the warmer valleys. Flood is the most common pasture irrigation method, with about 50 percent of the water coming from the USBR project. Pasture condition is fair, and most pastures have not been renovated or re- leveled for some time. Maintenance would increase the efficiencies of 60 to 80 percent of the systems. Alfalfa is customarily sprinkler- irrigated and well- managed. Although irrigation efficiencies are higher than for pasture, many sprinkler systems still need upgrading. Several irrigated crops are grown in the subbasin including cereal grains, potatoes, and strawberry plants. Forestland, range and pasture are grazed by livestock. Rangelands are comprised of juniper and sagebrush steppes. Forestlands are generally mixed conifer. Livestock operations include cow/ calf, stockers and dairies. Confined livestock operations are located throughout the subbasin. The location and duration of confinement may pose a potential risk to water quality. Seven dairies located within the subbasin have existing liquid and dry livestock waste storage facilities.

High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving over the last 10 to 20 years. While agriculture is the dominant land use in this subbasin, other sources of phosphorus and other pollutants exist. Sewage treatment outfalls, on- site sewage disposal systems, wildlife, and natural inputs also contribute nutrients and other pollutants to the system. While historically the river had significant fish runs, it currently supports only a small population of Shortnose and Lost River suckers. Conservation Accomplishments In the Upper Lost River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved resource conditions on 234 acres of croplands and 5,282 acres of grazing lands, and have improved their management of irrigation water on 5,596 acres of irrigated lands. In addition, 846 acres of riparian and wetland areas have been restored.

On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops. Implementing practices like diverting clean water before it flows through livestock confinement areas near water sources, will reduce the risk of polluted runoff. Water Demand: On both surface-irrigated pastures and cropland areas, there are opportunities for land leveling or smoothing, lining or piping irrigation delivery ditches, upgrading irrigation systems and developing tailwater recovery systems to improve water use efficiency.

Farms near Klamath Falls tend to be smaller, indicating part- time or hobby operations. The area includes 12 irrigation districts and leased lands on the Lower Klamath Wildlife Refuge that receive water supplied by the USBR Klamath Project. Public lands include the refuge, and parts of Modoc and Klamath national forests. Irrigated agriculture includes pasture, alfalfa, cereal grain, potatoes, onions and mint. Roughly 70 percent is irrigated with USBR- supplied water; the rest is obtained from groundwater, individual surface water rights or special USBR contracts. Many fields are either flood or sprinkler irrigated depending on the year and crop. Most farm irrigation diversions lack a means to measure water delivery. Livestock operations include several dairies and cattle feeding operations. Substantial range acreage is used for livestock grazing. Pasture condition is fair and most pastures have not been renovated or re- leveled for some time. Pastures associated with smaller livestock operations in and around Klamath Falls appear to be in the most need of improved pastures and irrigation systems. Wildlife habitat: Ten river miles are in relatively good riparian condition given the river is used for conveying irrigation water. Some 13 miles of stream lack adequate riparian vegetation and streambank protection.

Drought conditions and increased competition for available water have increased economic, social, political and environmental concerns and uncertainty over the future. Habitat and water quality are two additional major resource concerns in the subbasin. High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other pollutant sources exist. While the river had significant historic fish runs, it currently supports only a small sucker population. Conservation Accomplishments In the last two years, the Middle Lost River Subbasin has seen significant conservation progress. With assistance from NRCS and local conservation districts, land managers have improved the condition of natural resources on 489 acres of cropland and 3,521 grazing land acres. In addition, 564 acres of riparian and wetland areas have been restored, and water use efficiency has been increased on 3,731 acres of irrigated lands.

Highly effective conservation measures on hay and cropland should focus on updating existing irrigation systems and improving irrigation water management. Water Quality: The use of grazing systems that rotate livestock through smaller pastures will increase forage production, reduce soil compaction and improve water quality. While fishery benefits from restoring riparian areas are minimal, streamside buffers will improve water quality and provide habitat for other wildlife. On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops.

The Tulelake Irrigation District and the Tulelake National Wildlife Refuge receive water from the USBR Klamath Project. Tulelake is a remnant of historic Lake Modoc that once connected the subbasin with both Lower and Upper Klamath Lake. The Lost River watershed was once a closed basin. Runoff flowed into Tulelake and evaporated. Pumping plants and drains constructed as a part of the project have provided an outlet from Tulelake, which now functions as an open basin. Irrigated agriculture is generally supplied by the USBR. Alfalfa, grain, potatoes, onions, mint and pasture are the principal crops. Fields are flood or sprinkler irrigated depending on the year and crop. Often diversions lack devices to measure water delivery. Pasture condition is fair, and most have not been renovated for some time. Groundwater provides 40- 50 percent of water for irrigated pastures, and most excess water is reused. Rangeland is the other significant land use. Most ranches are cow/ calf operations that have winter holdings in the subbasin. Rangelands are generally encroached with juniper. Wildlife habitat along the Lost River has reeds and bullrush, providing some habitat for waterfowl and songbirds. Suckers have been located in the river and Tulelake; however, it is not known whether they are successfully reproducing. There are few opportunities to improve habitat along this heavily manipulated reach of the river.

Irrigators depend on water- use decisions made by fellow irrigators and resource managers for their irrigation needs. Drought and increased competition for water leads to the primary resource concern in the basin - a reliable supply of water to meet agriculture, wildlife and other resource needs. Water quality deteriorates as it moves through the USBR project. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other sources of phosphorus and other pollutants exist. The presence of ESA- listed suckers creates concerns for improving habitat and water quality. The two national wildlife refuges support large waterfowl populations. Farmland on the refuges is leased to farmers to supply grain for waterfowl and shorebirds. These populations depend on refuges, leased lands and adjacent farms during the fall and spring migratory periods. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Tulelake Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, local land managers have improved the condition of natural resources on 72 cropland acres and 1,854 irrigated land acres, and have restored 21 acres of riparian and wetland areas.

Subsurface drainage could be added before re- establishing alfalfa stands, permitting better control of water table and soil moisture levels. During years that alfalfa fields are rotated to grain, winter flooding or pre- season irrigation could be used to reduce water demand. Water Storage/ Yield: Adding subsurface drainage may be the most significant practice to implement on cropland acres. Subsurface drains would allow farmers to winter flood or pre-irrigate fields, thereby reducing their demand for water during the irrigation season. If pre- irrigated, farmers could grow a cereal crop even if water deliveries are cut off during drought years. In addition, juniper control on rangelands will yield additional water to meet downstream needs.

While part of the Upper Klamath Basin, it is an internal drainage basin with only an artificial outlet. Groundwater flows from west to east out of the subbasin under the Mahogany Mountains toward the lake. A channel and pump plant were built to remove floodwaters. This channel is used infrequently and for only short durations. The Klamath National Forest, Butte Valley National Grassland, and the Butte Valley Wildlife Area make up the majority of the public lands. Irrigated agriculture includes alfalfa hay as the predominate crop. Cereal grains, potatoes and strawberry plants are also grown. Crops are usually sprinkler irrigated, and sprinklers are well maintained. Few irrigators measure water applied or schedule irrigation. Cattle operations graze irrigated pastures and meadows scattered throughout the subbasin along with range and forestlands. Pastures are generally flood irrigated and are supplied by streams. Most farm irrigation diversions lack water measuring devices. Mixed conifer forests are found at higher elevations and are generally operated as industrial forests. Range sites are dominated by Western Juniper and are generally in poor condition. Wildlife habitat is generally wetlands in the state wildlife refuge or on national grasslands. Approximately 26 miles of streams on private lands have inadequate riparian vegetation.

Generally, streams in the upper portions of the subbasin support good populations of Brown and Rainbow trout. The Tulelake National Wildlife Refuge and Lower Klamath Lake National Wildlife Refuge support large populations of migratory and permanent waterfowl. Farmland on the refuges is leased to area farmers to supply grain for the waterfowl and shorebirds. The large bird populations depend on the refuges, leased lands and adjacent farms throughout the fall and spring migratory periods for habitat. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Butte Valley Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, local land managers have restored 27 acres of riparian and wetland areas in the last two years.

Other than limited contributions to groundwater in the Upper Klamath Basin, reductions in water demand only benefit the subbasin. Sprinkler- irrigated hay, cereal crops and row crops dominate land use on the better soils. Highly effective conservation on hay and cropland should focus on improving the overall irrigation efficiency of existing systems. This can be accomplished by upgrading systems and scheduling irrigation. An estimated 40 percent of the existing systems would benefit from maintenance. On controlled flood irrigated pastures, there are opportunities for land leveling or smoothing, lining or piping delivery ditches, and recovering tailwater. Additional water savings and water quality benefits could be gained by converting existing surface irrigation to sprinklers if power is available and affordable. On rangelands, juniper control and improved grazing management are the primary conservation opportunities.

Nearly half of the area is in public ownership. Iron Gate and Copco reservoirs are used extensively for recreational fishing, boating and camping. Whitewater rafting and kayaking are popular below the KC Boyle Dam. The KC Boyle, Copco and Iron Gate dams are used and regulated for power generation. Irrigated agriculture occurs on only 4,000 acres of pasture. Only a few isolated ranches are located in this subbasin. Cattle operations rotate grazing of irrigated pastures with significant acreage of grazed range and forest. Pastures are surface irrigated with a mix of controlled and flood irrigation. All irrigation water is diverted from the river or tributary streams. Most farm irrigation diversions lack devices to measure water. Even though overall irrigation application efficiency is low, the proximity of irrigated pastures to the river allows most excess water diverted to be reused downstream. Private forest and rangelands make up most of the private land, nearly all of which is used for livestock grazing. Much of the rangeland is in poor condition, with heavy juniper encroachment. More than half of the forest stands are overstocked with trees. Wildlife habitat along riparian areas is generally in good condition. Of the 12 miles of riparian areas surveyed, five would benefit from some restoration.

Water withdrawals are insignificant along this stretch of the river. Salmon and steelhead are blocked at Iron Gate Dam from upstream passage. Several resident trout species exist, supporting a recreational fishery. Conservation Accomplishments In the Klamath River East Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved the condition of natural resources on 56 acres of cropland, 332 acres of grazing land, and 560 acres of irrigated lands. They have also improved forestland health on 46 acres and have restored 924 acres of riparian and wetland areas.
