Irrigation and other agricultural practices in the U. S. Bureau of Reclamation's Klamath Project may result in impaired surface water quality, reducing its use for wildlife and fish in important national wildlife refuges that receive drainage water from farms, and in the Klamath River. By 2004, a system of total maximum daily loads (TMDL) for nutrients must be established for the Klamath River. To investigate the relationships among agricultural practices and surface water quality in the Upper Klamath Basin, a two year reconnaissance survey of surface water and agricultural tile drain locations, focusing on nitrogen and phosphorus concentrations and mass transfers was conducted. Data was collected at 18 surface locations and 10 tile drain locations. Triplicate samples were taken every ten days during the growing season (April through October) and one or two times a month during the remainder of the months, depending on opportunity. No samples were taken from tile drains during the winter months because there was no irrigation and drainage during that period. Water samples were analyzed for phosphorus (total P, soluble reactive P, total filterable P, and particulate P) and nitrogen (total N, soluble N, Soluble organic N, total filterable N, particulate N, and ammonia N), temperature, pH and electrical conductivity, a measure of salinity or total dissolved solids. Analyses of data, including data quality, estimates of the transfer of nutrients in surface waters in the region, and hypotheses about the relationship between agriculture and water quality are reported. 1. The salt and nutrient content of surface waters increases nearly threefold as water moves through the watershed from the Lost River and J canal diversion to the Klamath Straits Drain. Mean ECW levels in input waters at the J canal diversion were approximately 250 \iS cm1, while water sampled at the D pump increased to 600 ^S cm"1 on average over the sample period. By the time water reenters the Klamath River, salt concentrations have increased to approximately 700 jaS cm1. 2. The ECW values observed in subsurface tile drains were higher on average than in input waters and surface waters elsewhere in the region, especially in the Lease Lands area of the Tulelake Irrigation District (TID). ECW values averaged approximately 2,500 ^S cm"1 . Recycling irrigation water through soils in the TID increases the salinity of the water, especially by the time it reaches and is reused in the Lease Lands area of the Tulelake National Wildlife Refuge (TLNWR). Soils in this part of the Klamath Project area are naturally high in salt. 3. Water temperatures in agricultural subsurface tile drains were significantly lower than surface water temperatures during the growing season when tile drains were active. pH values in tile drains were lower than surface water values. The temperature and pH of tile drains does not influence surface water values. 1. 4. For total phosphorus (TP) input waters at the J canal irrigation diversion for the TED averaged approximately 0.27 mg L1 for the two years reported. Water leaving the Tulelake Sumps at the D pump increases to 0.33 mg L1. Water leaving the Lower Klamath National Wildlife Refuge (LKNWR) sampled at the start of the Klamath Straits Drain, averaged 0.33 mg L1, similar to those at the D pump. TP increased further to 0.40 mg L"1 a the end of the Klamath Straits Drain. The overall increase in P concentration in surface waters was much less than for salt, suggesting that processes other than simple enrichment are occurring, particularly those associated with the exchange of sedimentary P and aquatic plant species. TN increases from 2.3 mg L"1 to 4.0 mg L1 over the same pathway. Atomic ratios (TN:TP) of surface water samples remain constant at approximately 10:1 throughout the system, suggesting that the amount of sediment and other small particulate matter in surface waters affects the values observed. The amount of sediment is influenced in part by the agitation of surface water as it passes through pumps and over weirs. 5. The average seasonal TP value in tile drains beneath farm fields is approximately 0.34 mg L"1 . While average total P values in subsurface tile drains were not different from those found at the D pump and the LKNWR outlet, the range in values was great (0.1 to 0.8 mg L1). Similarly, high NO3 -N values were observed at times in tile drains. Very high values in tile drains lead to the inference that some fertilizer N and P is lost in drainage water, combined with nutrients derived from decaying soil organic matter. The amount estimated as lost is much less than the amount of surplus fertilizer P applied and the amount of P surmised to be mineralized from decaying soil organic matter. P from fertilizer and decaying organic matter appears to be accumulating in soils and lake sediments in the region. 6. Ammonia N concentrations are at or below the limit of detection in subsurface agricultural tile lines and one to two orders of magnitude below the values observed in surface soils. Un ionized ammonia increases with temperature. Values above 0.25 mg L1 were observed in late summer at several locations. 7. Some leaching of soluble salts and nutrients is unavoidable when crops are irrigated. P fertilizer is applied at rates higher than crop removal, while fertilizer n is applied at rates less than crop removal. Reduced fertilizer use can help bring P inputs and outputs into balance and may reduce further any avoidable losses of P. This objective should be the subject of an agronomic research program in the region. 8. Surface waters entering the TDD, the TLNWR, and the LKNWR are already enriched with N and P. It seems unlikely that reducing N and P losses from farming in the TID, if possible, would influence surface water quality sufficiently to make them significantly less eutrophic. For P, the hypothesized threshold concentration limiting algae growth in fresh waters is 5 to 25 times smaller than the values observed in waters entering the TID for irrigation use. The addition of 1. nutrients from agriculture probably does not influence significantly surface water quality in the region. Wetland sediments, large amounts of organic matter in soils, and water introduced for irrigation contain essentially unlimited amounts of nutrients for aquatic plant growth. It is not clear how this circumstance could be changed under any reasonable time frame, if ever. 9. Using a TMDL approach may not result in reduced amounts of nutrients returned to the Klamath River because wetlands and farming practices in the southern portion of the Klamath Project result in the net removal of nutrients from the waters diverted for irrigation on a yearly basis, compared to allowing the same amount of water simply to flow down the river unused. Because of large errors of estimation for the amounts of water transferred, combined with smaller errors associated with estimating nutrient concentrations in water samples, and with year to year climate variation, TMDLs may not be an effective or efficient means of reducing nutrients in return flows to the Klamath River. Rational confidence limits for TMDLs may have to be too broad to be effective. Recycling of some drainage water for irrigation would reduce the amount of nutrients returned to the river more effectively than implementing a TMDL program.

In 1996, the 104th Congress of the United States chartered the Upper Klamath Basin Working Group (Public Law 104-333 - the Oregon Resources Conservation Act) to develop a plan for the Upper Basin that focuses on enhancing ecosystem restoration, improving economic stability, and minimizing impacts associated with drought on all resources and stakeholders. The Working Group is comprised of over 30 individuals appointed by the Governor of Oregon, representing federal, state, and local governments and agencies; the Klamath Tribes; conservation organizations; farmers and ranchers; and industry and local businesses. The objective of the Working Group is to develop and oversee a restorative course of action that allows for mutually beneficial gains for stakeholders wherein everybody in the Upper Basin can achieve positive, affirming results together, and where no one is left economically, culturally, or spiritually disadvantaged. Chapter 1 of this report presents a brief summary of the history of the Working Group and the conditions leading to the development of this effort. Chapter 2 describes the facilitated "interim planning process" the Working Group engaged in between April 2001 and July 2002. Chapter 3 presents the results of the interim planning process including key recommendations regarding Working Group decision-making and operating rules, technical data needs, future cost and time frame of the restoration planning process, and similar planning decisions. Chapter 4 describes the next steps and actions the Working Group is prepared to take to lead the restoration planning process. The Working Group's goals and objectives will be achieved through the Working Group's continued commitment to public outreach, collaborative problem solving, and implementation of real world solutions. Desired outcomes from implementation of the restoration plan include, but are not limited to, the following: improved water quality through the implementation of accepted Best Management Practices; restoration of wetlands and riparian habitat; enhancement of natural and structural water storage; improvements to irrigation efficiency and water conservation; economic growth and diversity through activities such as value added natural resource products and ecotourism; and enhancement of wildlife Tribal Trust resources.

  	Citation × Citation Citation Abstract Copy Title: Raising Upper Klamath Lake, appraisal study : draft. Author: U.S. Dept. of the Interior, Bureau of Reclamation Year: 2000, 2008, 2005 Executive Summary This report documents an appraisal-level evaluation of raising Upper Klamath Lake in south-central Oregon. The lake is the State's largest freshwater lake and is a principal storage feature of the Klamath Project. The Klamath Project provides water for irrigating approximately 240,000 acres in the Klamath Basin in south-central Oregon and northern California. The Klamath Project was authorized for construction in 1905, and work began shortly thereafter. In 1921, Link River Dam was constructed at the south end of the lake, near the city of Klamath Falls, to provide regulation of the lake. Background The listing of fish species as threatened or endangered, and the Federal responsibility to protect Tribal trust assets, have placed increasing demands on the limited water supply of the Klamath Project and reduced its flexibility to meet demands. There is an immediate need to increase water supplies and improve the timing of their availability to improve fish and wildlife habitat and water quality. The Bureau of Reclamation (Reclamation) began the Klamath Basin Water Supply Initiative (Initiative) in 1996 to identify options for increasing water supplies in the Klamath River Basin. The Initiative is a joint effort partnership of Reclamation, the Klamath River Compact Commission, the California Department of Water Resources, and the Oregon Water Resources Department. The Initiative identified 96 options for increasing water supplies and recommended 44 for further study, including raising Upper Klamath Lake. Options Evaluated The evaluation documented in this report considers increasing the maximum operating level of Upper Klamath Lake by 2 feet by raising Link River Dam. Two options are described: (1) raising existing levees around the lake to contain the lake within its current surface area and (2) allowing the lake to spread and flood adjacent lands. Option 1 constrains the higher water surface elevation to the current shoreline. Modifications would be provided to protect all existing land, roads, and structures surrounding the lake. A 2-foot-high parapet will be constructed on top of the dam to accommodate the higher water level. Major construction activities include: Raising Upper Klamath Lake ? Eight sections of new seawall, totaling 6.6 linear miles ? Modifying 14 sections of existing dikes with roads, totaling 44.3 linear miles ? Modifying 10 sections of existing dikes without roads, totaling 25.2 linear miles ? Two sections of new dikes with roads, totaling 1.9 linear miles ? Three sections of new dikes without roads, totaling 2.7 linear miles ? Armoring two sections of existing dikes, totaling 3.5 linear miles ? Raising one bridge and county and local roads at seven locations, totaling 1.3 miles of roads ? Raising 2.5 miles of a State highway ? Rehabilitating 126 private residences (relocating septic tanks, providing foundation drainage, and landscaping) ? Rehabilitating headworks and intake structures at 10 locations ? Relocating an existing boat dock The estimated cost of Option 1 is $125 million. Option 2 does not protect structures and property, but, instead, allows the lake to spread beyond the current shoreline and flood adjacent lands. Existing dikes will be breached, and existing roads that would otherwise be inundated will be raised. Either existing headworks and water intakes at various locations will be retrofitted for the higher water surface elevation, or the associated facility will be purchased. Link River Dam will be modified as in Option 1. Major construction activities include: ? Breaching (every % mile) 14 sections of existing dikes with roads, totaling 44.3 linear miles of dikes ? Breaching 10 sections of existing dikes without roads, totaling 25.3 linear miles of dikes ? Armoring 3.0 linear miles of an existing dike ? Raising one bridge and county and local roads at three locations, totaling 0.6 mile of roads Executive Summary ? Raising 2.5 miles of an existing State highway ? Rehabilitating headworks and intake structures at nine locations ? Relocating an existing boat dock The estimated cost of Option 2 is $129 million, including $113 million for the acquisition of private land and structures. Raising Upper Klamath Lake 2 feet will increase storage by approximately 170,000 acre-feet, or about 25 percent. Winter floodflows, which are presently spilled to the Klamath River and not available for project use, will be stored and made available to help meet water needs for endangered species, Tribal trust resources, agricultural contractors, and national wildlife refuges. Future operation of the enlarged lake will be contingent upon acquisition of appropriate rights to divert and store additional water in the lake and may require filing an application for the appropriation of additional water with the Oregon Water Resource Department. Costs associated with implementing either Option 1 or Option 2 are significant. In addition, implementing either option will have both positive and negative impacts on the natural and human environment. Recommendations Several engineering studies are recommended. These include: ? Estimating quantities, properties, and availability of embankment and riprap materials, and identifying their locations (quaries) ? Constructing a modified dike test section to assess construction methodology and performance of rockfill protection ? Using detailed aerial topography (maximum 1-foot contours) of the Upper Klamath Lake shoreline to better define existing features and required improvements ? Conducting a comprehensive survey of all shoreline structures to provide a better estimate of the work required and associated costs ? Inspecting existing dam gates and concrete bulk heads to determine if additional modifications are required for the higher reservoir water surface ? S-3 Raising Upper Klamath Lake ? Developing site-specific, cost-effective alternatives to the proposed shore protection features ? Identifying and securing suitable rights-of-way Recreation facilities need to be analyzed in more detail to determine impacts and associated protection, relocation, and modification costs. A user survey and appropriate mapping of all recreational facilities has been initiated to determine existing recreation use levels and assist in the analysis of potential impacts. A detailed hydrology study demonstrating that unappropriated water is available to fill the additional storage in Upper Klamath Lake is recommended. Better descriptions of area-elevation-capacity relationships and evaporation and transpiration losses will also be needed. The following environmental studies are recommended: ? Develop detailed topographic information for the entire lake and surrounding area to predict the extent of flooding and potential vegetation changes ? Develop topographic mapping in 1-foot increments to predict effects on wetland vegetation ? Determine potential streamflow changes below Link River Dam and potential benefits to threatened and endangered fishes ? Determine impacts to upland areas that would be inundated by the higher reservoir water surface elevations. The following economic studies are recommended: ? Determine all costs (e.g., planning, design, construction, mitigation, and operation, maintenance, and replacement) ? Determine benefit/cost Early development and implementation of a public involvement plan will be essential to a feasibility study. Various studies to identify and analyze social impacts and impacts to environmental justice, Tribal trust, and cultural resources are recommended. Opportunities to avoid or lessen adverse impacts will also need to be identified. S-4 Title: Raising Upper Klamath Lake, appraisal study : draft. Author: U.S. Dept. of the Interior, Bureau of Reclamation Year: 2000, 2008, 2005 Executive Summary This report documents an appraisal-level evaluation of raising Upper Klamath Lake in south-central Oregon.

The Initiative identified 96 options for increasing water supplies and recommended 44 for further study, including raising Upper Klamath Lake. Options Evaluated The evaluation documented in this report considers increasing the maximum operating level of Upper Klamath Lake by 2 feet by raising Link River Dam. Two options are described: (1) raising existing levees around the lake to contain the lake within its current surface area and (2) allowing the lake to spread and flood adjacent lands. Option 1 constrains the higher water surface elevation to the current shoreline. Modifications would be provided to protect all existing land, roads, and structures surrounding the lake. A 2-foot-high parapet will be constructed on top of the dam to accommodate the higher water level. Major construction activities include: Raising Upper Klamath Lake ? Eight sections of new seawall, totaling 6.6 linear miles ? Modifying 14 sections of existing dikes with roads, totaling 44.3 linear miles ? Modifying 10 sections of existing dikes without roads, totaling 25.2 linear miles ? Two sections of new dikes with roads, totaling 1.9 linear miles ? Three sections of new dikes without roads, totaling 2.7 linear miles ? Armoring two sections of existing dikes, totaling 3.5 linear miles ? Raising one bridge and county and local roads at seven locations, totaling 1.3 miles of roads ? Raising 2.5 miles of a State highway ? Rehabilitating 126 private residences (relocating septic tanks, providing foundation drainage, and landscaping) ? Rehabilitating headworks and intake structures at 10 locations ? Relocating an existing boat dock The estimated cost of Option 1 is $125 million. Option 2 does not protect structures and property, but, instead, allows the lake to spread beyond the current shoreline and flood adjacent lands. Existing dikes will be breached, and existing roads that would otherwise be inundated will be raised. Either existing headworks and water intakes at various locations will be retrofitted for the higher water surface elevation, or the associated facility will be purchased. Link River Dam will be modified as in Option 1. Major construction activities include: ? Breaching (every % mile) 14 sections of existing dikes with roads, totaling 44.3 linear miles of dikes ? Breaching 10 sections of existing dikes without roads, totaling 25.3 linear miles of dikes ? Armoring 3.0 linear miles of an existing dike ? Raising one bridge and county and local roads at three locations, totaling 0.6 mile of roads Executive Summary ? Raising 2.5 miles of an existing State highway ? Rehabilitating headworks and intake structures at nine locations ? Relocating an existing boat dock The estimated cost of Option 2 is $129 million, including $113 million for the acquisition of private land and structures. Raising Upper Klamath Lake 2 feet will increase storage by approximately 170,000 acre-feet, or about 25 percent. Winter floodflows, which are presently spilled to the Klamath River and not available for project use, will be stored and made available to help meet water needs for endangered species, Tribal trust resources, agricultural contractors, and national wildlife refuges. Future operation of the enlarged lake will be contingent upon acquisition of appropriate rights to divert and store additional water in the lake and may require filing an application for the appropriation of additional water with the Oregon Water Resource Department. Costs associated with implementing either Option 1 or Option 2 are significant. In addition, implementing either option will have both positive and negative impacts on the natural and human environment. Recommendations Several engineering studies are recommended. These include: ? Estimating quantities, properties, and availability of embankment and riprap materials, and identifying their locations (quaries) ? Constructing a modified dike test section to assess construction methodology and performance of rockfill protection ? Using detailed aerial topography (maximum 1-foot contours) of the Upper Klamath Lake shoreline to better define existing features and required improvements ? Conducting a comprehensive survey of all shoreline structures to provide a better estimate of the work required and associated costs ? Inspecting existing dam gates and concrete bulk heads to determine if additional modifications are required for the higher reservoir water surface ? S-3 Raising Upper Klamath Lake ? Developing site-specific, cost-effective alternatives to the proposed shore protection features ? Identifying and securing suitable rights-of-way Recreation facilities need to be analyzed in more detail to determine impacts and associated protection, relocation, and modification costs. A user survey and appropriate mapping of all recreational facilities has been initiated to determine existing recreation use levels and assist in the analysis of potential impacts. A detailed hydrology study demonstrating that unappropriated water is available to fill the additional storage in Upper Klamath Lake is recommended. Better descriptions of area-elevation-capacity relationships and evaporation and transpiration losses will also be needed. The following environmental studies are recommended: ? Develop detailed topographic information for the entire lake and surrounding area to predict the extent of flooding and potential vegetation changes ? Develop topographic mapping in 1-foot increments to predict effects on wetland vegetation ? Determine potential streamflow changes below Link River Dam and potential benefits to threatened and endangered fishes ? Determine impacts to upland areas that would be inundated by the higher reservoir water surface elevations. The following economic studies are recommended: ? Determine all costs (e.g., planning, design, construction, mitigation, and operation, maintenance, and replacement) ? Determine benefit/cost Early development and implementation of a public involvement plan will be essential to a feasibility study. Various studies to identify and analyze social impacts and impacts to environmental justice, Tribal trust, and cultural resources are recommended. Opportunities to avoid or lessen adverse impacts will also need to be identified. S-4 Close

Bureau of Reclamation Year: 1958, 2008, 2006 INTRODUCTION AND GENERAL Genex*al Description of the Project Location. The Klamath Project is in the Upper Klamath River Basin, east of the Cascade Range. It is located in Klamath Comity, Oregon, and in Modoc and Siskiyou Counties of California. Project headquarters is located at the principal city of Klamath Falls, Oregon, which has a population of about 3&>^00, including suburbs. Smaller towns on the project in Oregon are Merrill, Malin, and Bonanza. The town of Tulelake, California, was established in 1931 near the center of the Tule Lake Division. Climate ? The mean temperature for the warmest month is 630 F. The coldest month has raez.n temperature of 29? F. Summer nights are cool. The annual rainfall is about 13 inches, of which about 3^ inches fall during the growing season of 90 to 130 days. Topography, soils, and crops. The project area is about U,100 feet elevation above sea level. The surface topography is generally smooth and flat for the large areas of lake bottom, and gently sloping on the higher lands? Peat and muck soils are common in the recent lake bottoms. Soils vary from sandy loam to clay on other parts of the project. The principal crops grown are alfalfa, malting and feed barley, potatoes, clover seed, and irrigated pasture and other forage. Stock raising is an important enterprise. Industry and transportation. Farming and lumbering each provide the major portion of the economy of the Basin. Three major railroad lines, one major highway and many secondary highways, and two airlines serve the project area. Plan and purpose. In 1958 the project provided irrigation service to 21^,500 acres. The water supply is provided by two main water courses, Klamath River and Lost River and their tributaries. Besides storing, diverting, and distributing water for irrigation, project facilities have reclaimed by drainage large areas formerly inundated by Lower Klamath and Tule Lakes. Flood waters of Lost River, which terminates In Tule Lake, are diverted to the Klamath River through the Lost River Diversion Channel. This channel is also used to carry irrigation water in the opposite direction in the summertime. Another principal function of the project is water-level control for the Tule Lake and Lower Klamath Lake National Wildlife Refuges. DTERODUCTIOH AND GBNKRAL (Continued) General Description of the Project (Cont.) Upper Klamath Lake on the Klamath River is the principal storage reservoir, having an active capacity of 52^,800 acre-feet. It is controlled by Link River Dam constructed, maintained, and operated by The California Oregon Power Company under an agreement with the project whereby irrigation requirements and rights are protected. The Main, Lower Klamath, and Tule Lake Divisions are served from this source. Gerber Reservoir on Miller Creel; and Clear Lake Reservoir on Lost River provide flood control for the Tule Lake Division and an irrigation supply for the Langell Valley Division. Their active storage capacities are 9*b3OO acre-feet and 513*300 acre-feet, respectively. Federally-financed project works also include the diversion, distribution, and drainage systems for the Main and Tule Lake Divisions; the diversion darn and main canals for the Langell Valley Division; and drainage outlets for the Lower Klamath and Tule Lake Divisions?
