The proposed project evaluates stream temperature and riparian condition before and after harvesting. Sites will be evaluated on both privately-owned and state-owed forestland. A pre/post- study design that establishes control, treatment, and downstream reaches, 2 years prior to harvest is proposed. Temperature, channel, overstory and understory riparian characteristics will be monitored two years prior to harvest and for 5 years after harvesting to evaluate harvest effects and recovery rates. This project approach, design, and proposed analysis will go through a review process involving reviewers from private research, DEQ, ODF&W, stakeholders, researchers, and representatives of the environmental caucuses.

  Citation × Citation Citation Abstract Copy Title: Oregon Chub Investigations at Hospital Pond, 2000-2008; Information Reports Number 2009-07 Abstract -- Previous studies suggested relationships between Lookout Point Reservoir water elevations, Hospital Pond water levels and temperatures, and Oregon chub spawning and recruitment in the pond. Hospital Pond is fed by large cold springs and spawning only occurs when the reservoir is nearly full and floods the pond terrace. Changes in flow management in the Middle Fork Willamette River occurred in 2000, following the listing of Willamette spring chinook and winter steelhead, and resulted in changes in the frequency and magnitude of reservoir filling and the length of time the reservoir would remain full. The US Army Corps of Engineers modified the pond in an attempt to allow managers the ability to manage water levels and temperatures in Hospital Pond independently from reservoir levels. We found that these modifications were largely unsuccessful. We found that strong year-classes were infrequent and occurred in several, but not all of the years, when the reservoir filled. Our data also suggests that strong year-classes may limit the recruitment of the following year-class through density-dependent mechanisms, i.e. competition for food and space. If the reservoir continues to fill every few years, as it has for the last decade, we feel that that Oregon chub recruitment in Hospital Pond will be adequate to maintain a stable population into the future.

The climate of this region is temperate and semiarid, characterized by low annual precipitation, low winter temperatures, and high summer temperatures. The fishery consists of warm-water game fish and trout. McKay and Cold Springs Reservoirs provide both types of fisheries while the remainder of the impoundments provide angling on stocked rainbow trout. The season is open the entire year on these waters with the exception of McKay and Cold Springs Reservoirs which are closed during the waterfowl nesting period. Since this area has only a limited supply of surface water, emphasis is being put on the construction of reservoirs which would impound runoff waters for angling and other recreation uses. At present, there are only six impoundments within the tri-county area. and these come far from meeting the public demand. An additional 15 reservoirs have been recommended for future development in order to provide adequate public fishing access.

  Citation × Citation Citation Abstract Copy Title: Upper Calapooia River Fish Monitoring Abstract -- The project will occur on the Upper Calapooia River, between the Holley Bridge (USGS RM 45.5) and the perceived end of anadromy for salmonids (USGS RM 72.9). Historically the Calapooia River marked the upper end of winter steelhead distribution in the Willamette Basin, and a spawning tributary for spring chinook. These are both DPS/ESU listed species, and little is known about their distribution and life history in the Calapooia River. A Rapid Bioassessment was completed in 2015 as well as winter steelhead redd survey in 2017 to try and establish baseline data including spawning gravel abundance/seeding availability, adult escapement, a foundation for long term trend analysis, as well as identify anchor habitats. The survey was also intended to inform ODFW with vital information regarding the possibility of jump-start seeding the Calapooia with Chinook, as well as guide the Calapooia WC’s restoration approach in this vital area. The 2017 return of Winter steelhead over the Willamette Falls (pinch point for all anadromy in the Willamette Valley) was the lowest on record, and the CWC and partners do not feel a proper baseline was established. The CWC proposes to complete 2 years of STW redd Surveys to create a baseline of adult escapement from 2 different cohorts, as well as collect summer water temperature data through the deployment of Hobo temperature loggers. This data can be used to create a reach wide restoration plan that will focus CWC restoration efforts in areas where they will be the most efficient and effective. Partners include ODFW, Weyerhaeuser, US Forest Service, Miners Association, and private residents.

  Citation × Citation Citation Abstract Copy Title: Habrate: A Limiting Factors Model for Accessing Stream Habitat Quality for Salmon and Steelhead in the Deschutes River Basin, 2010. Information Reports Number 2010-03 Abstract -- Fishery managers are commonly tasked with the basic question "Will the contemporary habitat above a barrier support the fish populations that historically resided in the watershed?" Managers in central Oregon were confronted with that question in an effort to reestablish fish populations in 375 kilometers of stream above the Round Butte-Pelton Dam complex (Rkm 161) on the Deschutes River. Stream surveys had been conducted in most of the available stream habitat, but had not been synthesized in a form that allowed managers to view the quality and complexity of stream habitat in an easily-understandable fashion. In response, we developed a limiting factors model (HabRate) that assessed the potential quality of stream habitat using stream survey data for each juvenile life stage of salmon and steelhead. The model was developed for a specific application to the middle Deschutes River basin in Oregon, but was intended for general application to Pacific Northwest basins. To paramatize the model, we summarized available literature on salmonid habitat requirements. Habitat criteria were developed for discrete life history stages (i.e. spawning, egg survival, emergence, summer rearing, and winter rearing) and used to rate the quality of stream reaches as poor, fair, or good, based on attributes relating to stream substrate, habitat unit type, cover, gradient, temperature, and flow. Reach level summaries of stream habitat data were entered into MS Excel, and interpreted by a series of algorithms to provide a limiting factor assessment of potential egg-to-fry and fry-to-parr survival for each reach. Model output lists habitat quality by species and life stage for each reach of stream. The model is a decision making tool that is intended to provide a qualitative assessment of the habitat potential of stream reaches within a basin context. Design criteria for the model were simplicity, flexibility, and transparency. While HabRate was based on our interpretations of the published literature, specific criteria for habitat quality were structured to be easily adjusted where interpretations differ from ours. Information not common to standard stream survey designs, such as seasonal flow or temperature extremes can be included as input from professional judgment. The results were integrated into a GIS coverage coupled with the stream network and habitat data to provide a comprehensive map-based perspective of habitat quality in a watershed.

The stream below Keno Dam and below the Boyle powerplant fluctuates from power production and irrigation manipulation. The five-mile section immediately downstream from Boyle Dam is the only portion that remains relatively stable. Low quantitites of dissolved oxygen and high water temperatures are chronic problems in the Keno area and adversely affect the river downstream. Most spawning gravel is located in Spencer Creek. The main river has a poor gravel supply. Competition from the various fish species in Boyle Reservoir has undoubtedly impacted the trout population and the spawning run into Spencer Creek. The Klamath River may be the most productive stream in Oregon. Although it has limitations on its production capabilities, it will be managed for wild trout only.

  Citation × Citation Citation Abstract Copy Title: Little Deschutes Subbasin Watershed Assessment Abstract -- Many of the impacts to fish and wildlife habitat and water quality in the Little Deschutes River Subbasin are concentrated in the areas of housing, roads, and other human development. Most of the human population in the subbasin is concentrated around the community centers of La Pine, Gilchrist, Crescent, and Crescent Lake. There is significant dispersed development along the lower reaches of the Little Deschutes River between the communities of Sunriver and La Pine -an area characterized by gentle topography and depressions with forested wetlands, marshes and shallow lakes. Streams in this area, as illustrated by the Little Deschutes River , are low gradient and originate in the high elevation areas in the southwest portion of the watershed where there is higher precipitation. This ownership pattern has significant implications for natural resource management, as lower gradient floodplain areas tend to provide important wetland, fish, and wildlife habitat. Key Findings Fuel Loading: Having homes safe from wildfires is a concern for many residents. Fire suppression has increased the amount of dry wood in the area, creating a ready source for major wildfires. Riparian Areas and Wetlands: Loss of wetland and riparian areas , especially in the lower areas along the Little Deschutes River , has affected a number of resources. Water quality has been affected by the reduced wetlands that act as filters of nitrogen; the loss of streamside trees and other vegetation reduces shade that helps to cool water temperatures. Finally, loss ofwetlands and riparian vegetation has reduced important fish and wildlife habitats. Wildlife: The growth and development have altered wildlife habitats. Loss of wetlands, streamside vegetation, and other changes in the watershed have reduced important wildlife habitat. Roads and development have impacted migrating mule deer, increasing collisions between deer and cars and altering their migration pathways. Fish: There has been a significant loss of native trout and an increase in introduced brook and brown trout in the Little Deschutes River and tributaries. Loss of native trout is from competition with introduced species and changes in aquatic habitat and water temperatures. Water Quality: A major concern about the water in the river is unusually high temperatures in the summer and the abnormal growth of algae. Other studies indicated that there are problems with groundwater loading ofnitrogen. The high water table (with associated wetlands), and porous pumice soils contributes to increased nitrates, a by-product of septic systems and an indicator of human pathogens.

  Citation × Citation Citation Abstract Copy Title: Hult Reservoir (Siuslaw Basin) Fish Species Composition Size and Relative Abundance_Final2018 Abstract -- Seven species of fish were encountered in Hult Reservoir in 2017: largemouth bass (Micropterus salmoides), cutthroat trout (Oncorhynchus clarkii), tainbow trout/winter steelhead (Oncorhynchus mykiss), bluegill (Lepomis macrochirus), reticulate sculpin (Cottus perplexus), brown bullhead (Ameiurus nebulosus) and western brook lamprey (Lampetra richardsoni). The most abundant fish observed were largemouth bass and bluegill in the summer and fall, and cutthroat in the winter. Cutthroat trout were much more prevalent in the fall and winter sampling than in the summer. Presumably, most cutthroat trout moved up into the tributaries to seek thermal refuge during the summer months and returned to the reservoir once the temperatures were more conducive to growth and survival. However, some of them likely moved downstream, were preyed upon, or perished from the high summer temperatures and low dissolved oxygen conditions in the reservoir in summer. Under current conditions, high surface temperature (>20?), bass predation, and hypoxic dissolved oxygen levels below four meters of depth show that reservoir conditions are inhospitable for juvenile salmonids in the summer. Currently there are well established fisheries for both cutthroat trout (spring, fall, winter) and largemouth bass (summer) in the reservoir, and we talked to several anglers who target each of these species. Habitat segregation in the summer between the salmonids who move out of the reservoir and the warm-water fish that remain and spawn in the reservoir results in a diversified year-round angling opportunity. There were no coho salmon (juvenile or adult) observed in Hult Reservoir in 2017, but adult coho salmon were observed spawning just downstream of the dam. This observation verifies that a proportion of the adult coho attempting to ascend the ladder at Lake Creek Falls are successful and continue migration upstream to the vicinity of Hult Reservoir. It may be possible to keep the current fishery in Hult Reservoir as it stands and still increase coho production in the system by improving adult passage at Lake Creek Falls, and possibly at Hult Dam.

We had three primary study objectives: 1) examine redband trout spawning locations and spawning migration timing, 2) evaluate redband trout passage at diversion dams, and 3) investigate seasonal migration patterns of redband trout as they relate to stream temperature dynamics. We tagged 96 redband trout with radio transmitters and 706 with PIT tags. Radio tracking included both mobile and fixed station detections. We established PIT tag readers at Cato Bridge (Rkm 1), Busse Dam (Rkm 35), Grain Camp Dam (Rkm 48), and Page Dam (Rkm 76) for additional data on large-scale movement patterns. With the PIT antennas at the three diversion dams, we placed one antenna below the dam and one at the upstream exit of the fish ladders to evaluate the passage delays at each dam. Stream temperature was recorded at 10 locations in the Blitzen River throughout the study. Scales of 257 migratory trout were interpreted for age and spawning history. Our results indicated that the majority of Blitzen redband trout migrated upstream of Page Dam to spawn and that most trout spawned in the mainstem and not the tributaries. Upstream trout migration occurred from March to July, but the peak migration occurred during late April and early May. Passage problems were recorded at two of the three dams evaluated. Trout were delayed longest at Busse Dam and 44% of radio-tagged trout that approached the dam were never able to pass. Trout experienced less delay at Grain Camp Dam and only 8% of radio-tagged trout failed to pass the dam. At Page Dam, which has a recently upgraded fish ladder, trout delays were short and only 5% of trout that approached the dam were unable to pass. Potentially stressful or lethal temperatures (>24.3°C) were recorded at all monitoring locations downstream of Fish Creek, except at the site just below Page Springs. The migratory population ranged in age from 1+ to 5+, but only age 3+ and older trout were reproductively mature. This suggests that the spring upstream migration includes both adult trout seeking suitable spawning habitats and immature trout making a seasonal habitat shift for thermal refuge. A fraction of the PIT-tagged fish were observed to make two or three migrations from below Busse Dam to above Page Dam in the spring and returning back to the lower river in the fall. We recommend prioritizing fish passage at the Busse Dam and Grain Camp Dam for conservation and enhancement efforts.

Degraded floodplain and channel structure, altered sediment routing, altered hydrology, and water quality (temperature) are cited as limiting factors in the Draft Mid-Columbia Steelhead Recovery Plan (Carmichael 2008). Current and proposed restoration efforts for the MFJDR_IMW are anticipated to address these key limiting factors. In order to assess restoration effectiveness on focal fish species, monitoring and analyses must emphasize population level spatial scales. Fish population monitoring for the MFDJR_IMW includes evaluating summer steelhead and spring Chinook population productivity, survival, and abundance. While abundance is an important metric for population assessments, survival and production will also be key indicators of population responses to planned restoration activities. Freshwater survival is assessed from the parr to smolt life stages (parr to smolt survival) and ocean or out-of-basin survival is estimated as a smolt to adult return ratio (SAR). Freshwater productivity is assessed as smolts produced for constructed redds (smolts/redd). ODFW, Eastern Oregon fish Research (EOFR). Funded by Oregon Watershed Enhancement Board (OWEB).

  Citation × Citation Citation Abstract Copy Title: Abundance Monitoring of Juvenile Salmonids In Oregon Coastal and Lower Columbia Streams, 2007 Report Number: OPSW-ODFW-2008-1 Abstract -- As part of the Oregon Plan for Salmon and Watersheds, the Oregon Department of Fish and Wildlife (ODFW) initiated a project in 1998 to monitor the trend in abundance and distribution of juvenile coho salmon (Oncorhynchus kisutch) rearing in Oregon coastal streams. Monitoring is currently designed to provide annual abundance and distribution information at the stratum-scale (described in Jepsen and Leader 2007) for each of several coho evolutionarily significant units (ESU’s) and steelhead distinct population segments (DPS’s), and to eventually use these annual data to provide longterm trend information. Ultimately these juvenile fish data will be used to investigate relationships between freshwater habitat characteristics, adult spawner abundance, and juvenile recruitment. This progress report summarizes abundance and distribution data collected in 2007 for each ESU and DPS, and for the Oregon Coast Coho ESU includes a time series for abundance data for all years of monitoring. A fuller description of the OCC, OCS, SONCC and KMPS sampling frames, study design and survey methods, is found in Jepsen and Rodgers (2004) and for the LCRC and LCRS frames in Jepsen and Leader (2007). The strata are diagramed in Figure 1 and organized in subsequent tables. At a subset of the OCC sites, this project also collects water temperature data and macroinvertebrate data in conjunction with Oregon Department of Environmental Quality. These data will be reported separately, and can be requested from project staff. In addition, the project re-initiated a snorkel and electrofishing verification study in the Smith River basin, which will be summarized in a separate report.

The lake and adjacent lands, are managed by the Forest under recreation and visual classifications. The water of the lake is state-owned and the fish resources are managed by the Oregon Department of Fish and Wildlife (ODFW). Hosmer Lake is a natural lake located about 40 miles west of Bend via County Road 46 (Century Drive) and Forest Road 470. One main campground, one overflow campground and a concrete boat ramp are managed by the Deschutes National Forest. Hosmer Lake covers 160 surface acres and lies at an elevation of 4,950 feet. Maximum water depth is 11 feet and most of the lake is very shallow. The only inlet to the lake is Quinn Creek, a spring-fed stream with a flow of 25 cfs and a near-constant temperature of 42°F. Hosmer Lake contains Atlantic salmon ("Salmo salar") and brook trout ("Salvelinus fontinalis"). The lake was chemically treated in 1957 to remove a population of carp ("Cyprinus carpio"), Tui chub ("Siphateles bicolor") and brook trout. The treatment successfully removed all carp and Tui chub, but not all brook trout. Non-game fish have not reappeared since 1957. Originally, it was hoped the Atlantic salmon would spawn successfully in Quinn Creek. However, they cannot ascend the six-foot falls in lower Quinn Creek. The pumice bottom and annual anchor-ice scouring also nullifies egg development. The population of salmon at Hosmer has been maintained soley by hatchery fish since 1958.

  Citation × Citation Citation Abstract Copy Title: Siuslaw River Basin Fish Management Plan 1997 Abstract -- The Siuslaw River Basin is one in a series of similar watersheds in the Oregon coastal mountain range extending from the Nehalem to the Coquille. Rivers and streams in these watersheds generally occur in a forest dominated landscape, have moderate gradients, and medium to large estuaries. There are few dams that substantially affect anadromous fish runs. Water withdrawals impact only a small portion of the total miles of stream habitat. Water quality and temperatures are suitable for salmonids for the entire year in most areas. Rainfall throughout the area is heavy, resulting in a high density of streams relative to watershed area. The Siuslaw River system alone has over one thousand contiguous miles of stream suitable for salmonids. Some of these stream reaches are highly productive, while others are severely degraded.

The sustainability of the North Umpqua steelhead population and its' habitat is a very high priority. The Oregon Department of Fish and Wildlife (ODFW) develops, on a continuing basis, practices designed to ensure the health and viability of this population. However, continued management success depends critically on the availability of data necessary for a detailed understanding of relevant life history issues. To address these data needs, ODFW began a radio-telemetry study of North Umpqua steelhead in June of 1998. Tagging at Winchester dam was terminated 10/26/00 but monitoring continued until the end of May 2001. This study has provided detailed information on movement patterns of adult steelhead in the basin at a level that is available in no other way and is the most comprehensive project of its type for the Umpqua Basin. A radio tagging study whose scope was limited to the Steamboat Creek subbasin was carried out previously (Wroble, 1990). Also, a previous study of temperature trends in that subbasin is of interest (Hostetler, 1991). Although similar radio telemetry studies ( e.g. Hockersmith et al, 1995) have been carried out in other basins, they are few.

Twenty of these lakes were located and named by the survey crew. Of this group of 20, four had fish present, although there was no recorded name or stocking record. An additional 27 potholes and shallow lakes were explored and followed to be unsuitable for fish. These factors are listed in the Appendix. Data collected on the lakes included water and air temperatures, the approximate depth and bottom types, presence of natural reproduction, angling pressure and the general condition of the fish population. Special attention was paid to the accessibility of the lakes. A sample of the fish was taken by angling or gill net sets. The female fish were weighed, measured and examined for sexual maturity. The degree of sexual maturity was classed as mature, maturing and immature. The lakes, in general, are so widely separated in this section of the Cascade that it is difficult to group them in specific basins, therefore, these lakes have been grouped in the Willamette National Forest and the Mt.

The information was collected as part of a major John Day River fish screening program designed to protect juvenile Salmon and Steelhead from perishing in irrigation diversion ditches throughout the John Day Basin. The program was started and funded in 1952 under the Columbia Program Office of the National Marine Fisheries Service. The actual construction, operation and maintenance of the fish screens was done under contract by the then Oregon State Game Commission (OSGC), later to become the Oregon Department of Fish and Wildlife. These Data were actually collected on site by the screen maintenance technicians hired by OSGC to service and maintain the installed screens and bypass fish traps. At least one or more bypass traps were installed on each major stream with screens throughout the basin and all fish caught in the screen bypass traps throughout the irrigation season were counted to evaluate the effectiveness of the program. These technicians would check the traps and take stream temperatures from one to five times per week throughout the irrigation season which usually ran in the early years from mid March through mid November. The central maintenance shop for the John Day fish screen program was constructed in 1952-53 near Canyon City, Oregon and operateq in that location for over forty years (1953- 1994) until a new facility was built west of John Day, Oregon in 1994.

At least one or more bypass traps were installed on each major stream with screens throughout the basin and all fish caught in the screen bypass traps throughout the irrigation season were counted to evaluate the effectiveness of the program. These technicians would check the traps and take stream temperatures from one to five times per week throughout the irrigation season which usually ran in the early years from mid March through mid November.

  Citation × Citation Citation Abstract Copy Title: OWEB Grant Number 208-2084 Project Completion Report - PUR Monitoring Abstract -- While it is assumed that habitat enhancement and fish passage improvements increase fish production, there is little empirical data to support that claim in the Umpqua Basin. The Umpqua District has used smolt traps in the past to both establish a baseline record and to attempt to determine any response to habitat enhancement (Brush, Hinkle, and Big Tom Folley Creeks). Brush Creek and Big Tom Folley were originally chosen as monitoring sites since they are similar in characteristics, and Brush was originally the treatment stream for restoration projects while Big Tom Folley was used as the control until later projects occurred. Currently, there are PUR habitat enhancement projects scheduled to take place within the Little Wolf Creek and Wolf Creek basins. In order to gain more insight as to whether restoration efforts improve fish populations and address limiting factors, baseline and post treatment surveys will be needed. Restoration that is planned in Wolf and Little Wolf Creeks in 2008 and 2009 provides a unique opportunity to examine stream and fish responses to log-only and boulder-only instream placements. Pre-treatment data exists on these streams for smolt outmigration, summer habitat, spawning adults, summer seeding, channel cross-sections and temperature. ODFW has been collecting smolt out-migration data at five sites in the Upper Umpqua and Elk Creek watersheds almost continuously for 15 years to monitor yearly trends and to calculate over-winter survival rates of coho and steelhead. This OWEB grant will add to this baseline data and provide funding to continue past monitoring and add new monitoring components. Continuous smolt trap data from Brush, Big Tom Folley, and Hinkle Creeks is important to future efforts to monitor watershed health. Extensive habitat enhancement and fish inventories have been completed within the Hinkle Creek, Brush Creek and Big Tom Folley Creek basins. The Oregon Department of Fish and Wildlife (ODFW) Umpqua Watershed District joined with the Partnership for the Umpqua Rivers (PUR) in an effort to continue ongoing juvenile monitoring within the Umpqua Basin. Since little is known about stream-specific limiting factors and fish production response to various habitat restoration treatments such as log or boulder placement, these long term data sets will help to understand the fish response aspect related to or resulting from habitat restoration projects.

  Citation × Citation Citation Abstract Copy Title: Luckiamute Rapid Bio-Assessment Abstract -- The 2011 Rapid Bio-Assessment inventory of the Luckiamute Watershed was a replicate inventory that attempted to target the most productive salmonid habitats in the basin. This was the fourth consecutive inventory in the basin designed to describe the distribution and relative abundance of coho, cutthroat trout and winter steelhead. The entire basin (214 stream miles) was inventoried in 2008 utilizing the RBA protocol which included many miles of dysfunctional aquatic habitats that currently exhibit deep channel entrenchment, elevated summer temperature profiles and provided limited summer production potential. Survey efforts were reduced to 96.6 stream miles in 2009 and covered only the highest quality habitat reaches. Surveys were further refined in 2010 to a subset of the highest quality habitats (90.2 stream miles) and reduced again in 2011 to 84.6 stream miles. Some streams in the basin were also surveyed in 2002 and 2003 in a separate effort funded by Boise Cascade, the previous owner of the current Forest Capital holdings. These included Beaver, Boulder, Clayton, Cougar, Miller, Pedee, Ritner, Sheythe, West Fork Luckiamute, Wolf, and approximately 7 miles of the upper Luckiamute mainstem. Results and comparisons to those surveys are included below in the Site Specific observations. The intent of the RBA inventory was to gather information on the status of juvenile salmonid summer distributions and summer rearing densities. The inventory consisted of extensive snorkel surveys that began at the mouth of each stream and continued to the end of significant salmonid rearing potential (not to the end of cutthroat distribution). These surveys will be used to develop a base line for understanding how juvenile salmonids are currently utilizing habitats within the basin during summer flow regimes. Replicates of this inventory in high priority stream reaches (streams exhibiting residual system function) will be critical for identifying trends in the distribution and abundance of juvenile coho, steelhead and cutthroat in response to watershed restoration and management. The Rapid Bio-Assessment (RBA) survey method was designed to sub-sample 20 percent of the pool habitats using a Rapid Assay technique that could cover large distances and succeed in describing the current distribution of juvenile salmonids in all of the surveyed streams and their tributaries. Beaver dam frequency was also recorded.

The study objectives were to provide information on juvenile Chinook salmon distribution, relative growth rate, predator/prey interactions, and other population characteristics. In addition, we tested the feasibility of various gear-types and techniques for sampling juvenile Chinook salmon rearing in a reservoir environment. A variety of techniques were necessary to capture juvenile Chinook salmon as reservoir conditions and fish behavior, size, and distribution within the reservoir changed throughout the year. Nighttime snorkel surveys were the least invasive and most productive method to investigate habitat utilization and fry distribution early in the Spring. Minnow traps, hoop nets, Lampara seining, and mid-water trawling were largely ineffective at sampling fry and larger-sized juveniles. Oneida Lake trap nets were the most effective at capturing larger-sized juvenile Chinook salmon when reservoir surface temperatures remained cool.

  Citation × Citation Citation Abstract Copy Title: Downstream rearing of juvenile Chinook salmon abundance, distribution and growth in the Upper Mainstem of the John Day River Abstract -- Juvenile spring Chinook (Oncorhynchus tshawytscha) emerge from the gravel in the late winter or early spring, and most follow a life history pattern known as Natal Reach Rearing (NRR) in which juvenile fish remain in the stream reaches where they were spawned until their second spring of life when they start migrating towards the ocean (Healey 1991). However, in Columbia River tributaries, some juveniles have been observed following a Downstream Rearing (DSR) life history, in which they start moving downstream during their first spring towards other nursery habitats or perhaps ocean rearing (Copeland & Venditti 2009; Schroeder et al. 2016). Rearing in different habitats during their first year gives fish with these two life histories access to diverse food resources and, it is hypothesized that, this leads to different survival and growth advantages for these two groups. Differences in growth are of interest in efforts to conserve this threatened species because size is positively correlated to survival for salmon across multiple stages of their life cycle (Groot & Margolis 1991; Healey 1991; Quinn & Peterson 1996; Roni et al. 2012) Chinook salmon in the upper John Day River, Oregon, exhibit both NRR and DSR life history patterns. Fish following the DSR life history pattern are larger than NRR fish late in the spring, possibly due to factors such as higher fish density, lower stream productivity, and colder water temperatures in their natal reach than in the downstream reaches. However, this size advantage may be lost due to adverse summer conditions. Hot summer days combined with the withdrawal of water for agriculture lead to stream water temperatures well above lethal thresholds for salmon in many downstream reaches. DSR fish have been observed in tributaries of the mainstem John Day River, however their growth and survival during summer is unknown.

DSR fish have been observed in tributaries of the mainstem John Day River, however their growth and survival during summer is unknown. Close

  Citation × Citation Citation Abstract Copy Title: Yachats River Basin Fish Management Plan 1997 Abstract -- The Yachats River Basin is one in a series of similar watersheds in the Oregon coastal mountain range extending from the Nehalem to the Coquille. Rivers and streams in these watersheds generally occur in a forest dominated landscape, have moderate gradients, and medium to large estuaries. There are few dams that substantially affect anadromous fish runs. Water withdrawals impact only a small portion of the total miles of stream habitat. Water quality and temperatures are suitable for salmonids for the entire year in most areas. Rainfall throughout the area is heavy, resulting in a high density of streams relative to watershed area. The Yachats River system has about 69 contiguous miles of stream suitable for salmonids. Some of these stream reaches are highly productive. The Yachats River Basin has traditionally been managed for production of wild salmonids. Few hatchery fish have been released in the Yachats River Basin historically and none has been released in the past several decades. All salmonid species in the Yachats River Basin are at depressed levels with the exception of resident cutthroat trout. The depressed status of Yachats River Basin fish stocks has resulted from human induced factors including habitat degradation, excessive harvest, and hatchery influence (from adjacent streams) in combination with natural events such as droughts, floods and El Nino ocean conditions. As human induced factors are controlled and corrected, it is expected that fish abundance will increase substantially, but it is not possible to accurately forecast the shape recovery will take. In addition to the confounding effects of natural environmental variation, the recovery of individual fish species due to reduction in human impacts can only be loosely surmised. For this reason, this management plan will treat specific management targets for individual species as secondary to recovery of the entire basin and assemblage of fish species.

  Citation × Citation Citation Abstract Copy Title: Hood River Bull Trout Abundance, Life History, and Habitat Connectivity, 2007 Progress Reports 2007 Abstract -- Hood River bull trout are thought to exist as two independent reproductive units (USFWS 2004), known as local populations (Rieman and McIntyre 1995). The Clear Branch local population is isolated above Clear Branch Dam, which provides limited downstream fish passage during infrequent and sporadic periods of spill and no upstream passage. Bull trout in this population inhabit Laurance Lake Reservoir and tributaries upstream of Clear Branch Dam. The Hood River local population occurs in the mainstem Hood River and Middle Fork Hood River downstream of the Clear Branch Dam and a small number of adult bull trout migrate each year into the Hood River from the Columbia River (Figure 1). The status of both populations is extremely precarious. The Clear Branch population is at risk of a random extinction event due to low numbers, negative interactions with non-native smallmouth bass, isolation and limited spawning habitat (USFWS, 1998). The Hood River population also appears to be small and is threatened by passage barriers, unscreened irrigation systems, impaired water quality and periodic siltation of spawning substrate by glacial outbursts. Clear Branch bull trout spawn in Clear Branch and Pinnacle Creek. After rearing in these two natal streams for an unknown time period, most are believed to migrate downstream to Laurance Lake Reservoir. Clear Branch bull trout have been documented passing over the dam spillway during high water events (Pribyl et al. 1996) and may provide a recruitment source for the Hood River local population. Adult bull trout tagged at Powerdale Dam have been observed at Coe Branch irrigation diversion and in a trap at the base of Clear Branch dam. These fish may have been attempting to reach spawning areas located upstream of the dam. However, the success of bull trout migrating downstream via the spillway or the possibility of successfully navigating through the diversion network has never been determined. Depending on the water year, the Middle Fork Irrigation District (MFID) may not spill at all, or the timing of the spill may not coincide with the timing of downstream migration, which is currently unknown (East Fork Hood River and Middle Fork Hood River Watershed analysis). Smallmouth bass were discovered in Lake Laurance Reservoir in the 1990s. Creel surveys have shown that large adult bass are caught occasionally in the reservoir and schools of bass fry have been seen by district fish biologist (Rod French, ODFW, personal communication), suggesting that they are spawning successfully. This illegal introduction poses a potential threat to the Clear Branch bull trout population, but its magnitude is unknown because the bass population size and degree of interaction between the two species are unknown. Bull trout and smallmouth bass have significantly different temperature preferences and tolerances, with bull trout being one of the most sensitive coldwater species and bass being a warm water species. Lake Laurance, a relatively high-altitude reservoir at 890 m (2,920 feet), does not provide ideal bass habitat so these two species may have largely non-overlapping distributions or differing activity periods (Terry Shrader, ODFW warmwater fish biologist, personal communication). However, based on past reservoir temperature data (Berger et al. 2005), there are periods in the reservoir when there is potential for bull trout and bass interaction: periods when bull trout are susceptible to bass predation and when juvenile fish might compete for resources. Spawning activity of the Hood River local population has been observed in a few locations within the Middle Fork of Hood River (Figure 1). Although consistent and extensive spawning areas for this population are not known, some of the locations where juvenile rearing or potential bull trout redds have been observed include the Middle Fork Hood River and some of its tributaries: Bear Creek, Compass Creek and Coe Branch (USFWS 2004). However, Coe Branch, Compass Creek, and the Middle Fork are glacial streams with a high volume of sand and silt which may compromise spawning success. No bull trout spawning or rearing has been observed on the East and West Forks of Hood River. The Middle Fork and mainstem Hood River provide foraging, migration and overwintering habitat. Hood River bull trout are also known to migrate into the Columbia River. Two bull trout tagged at Powerdale Dam (RK 7.2 of mainstem Hood River) were recovered near Drano Lake in Washington State; and one was captured 11 kilometers downstream of the confluence of the Hood and Columbia Rivers (USFWS 2004). Every year (usually between May and July), adult bull trout, presumably migrating upstream from the Columbia River, are captured and anchor tagged at Powerdale Dam. Although some of these tagged fish have been observed upstream (one in Coe Branch and three below Clear Branch dam), the spawning destination of fluvial adults within the Hood River basin is largely unknown. Dispersing juvenile bull trout and migrating adults in this local population are threatened by flow diversions with inadequate screening and passage facilities. Several structures are suspected to impede upstream migration or entrain juvenile and adult bull trout into irrigation works (Pribyl et al. 1996, HRWG 1999). These structures include: the diversion at Clear Branch Dam (passage and screening), Coe Branch (passage and screening), and the Farmers Irrigation District diversion (screening) on the mainstem Hood River (HRWG 1999). However, little research has been conducted to assess the impacts of these structures on migrating bull trout. Beyond a general knowledge of the distribution of Hood River bull trout and the nature of anthropogenic factors that potentially restrict their life history and habitat connectivity, little is known about this recovery unit. Baseline information about adult abundance is lacking for both local populations, the potential of a source (Clear Branch) and sink (Hood River) relationship between the two local populations has not been explored, and the migratory life history of adult fish caught at Powerdale Dam is unknown. The degree to which irrigation and hydropower diversions hamper connectivity within the Hood River basin is also poorly understood. Migratory life histories have been viewed as key to species persistence (Rieman and McIntyre 1995; Dunham and Rieman 1999), and understanding movement patterns and associated habitat requirements are critical to maintaining those migratory forms (Muhlfeld and Morotz 2005; Hostettler 2005). Gaining this information is also critical to evaluating bull trout recovery in the Hood River Subbasin (Coccoli 2004). The Oregon Department of Fish and Wildlife (ODFW) initiated a study in 2006 to improve our understanding of the abundance, life history, and potential limiting factors of the bull trout in this recovery unit. This report describes findings for the first two years of the study (2006-2007). Specific study objectives for the first two years were: 1. Determine the migratory life history of Hood River bull trout and assess the potential impacts of flow diversions and two new falls on the Middle Fork Hood River (scoured by the November 2006 glacial outburst) on bull trout migrations. 2. Determine current distribution of bull trout reproduction and early rearing in historical and potential bull trout streams in the Hood River Subbasin. 3. Determine the juvenile and adult life history the Clear Branch local population and develop a statistically reliable and cost-effective protocol for monitoring the abundance of adult Clear Branch bull trout. 4. Assess the potential impact of smallmouth bass on bull trout in Laurance Lake Reservoir.

  Citation × Citation Citation Abstract Copy Title: 2006 Borax Lake Chub Investigations Progress Reports 2006 Abstract -- Borax Lake chub (Gila boraxobius) is represented by a single population that inhabits a 4.1 hectare geothermally-heated alkaline lake in Harney County, Oregon. The Borax Lake chub is a small minnow endemic to Borax Lake and adjacent wetlands in Oregon’s Alvord Basin (Williams and Bond 1980). Borax Lake is a natural lake, perched 10 meters above the desert floor on sinter deposits, which is fed almost exclusively by thermal groundwater. The Borax Lake chub was listed as endangered under the federal Endangered Species Act in 1982 (U.S. Fish and Wildlife Service 1982). Population abundance estimates obtained in 1991-1996 indicated a fluctuating population ranging from a low of 8,144 fish to a high of 34,634 fish (Salzer 1997). The basis for the Borax Lake chub’s listed status was not population size, but the security of a very limited, unique, isolated, and vulnerable habitat. Because Borax Lake is situated above salt deposits on the desert floor, alteration of the salt crust shoreline could reduce lake levels and the habitat quantity and quality available to Borax Lake chub. At the time of the listing, Borax Lake was threatened by habitat alteration caused by geothermal energy development and alteration of the lake shore crust to provide irrigation to surrounding pasture lands. The Borax Lake chub federal recovery plan, completed in 1987, advocated protection of the lake ecosystem through the acquisition of key private lands, protection of groundwater and surface waters, controls on access, and the removal of livestock grazing (U.S. Fish and Wildlife Service 1987). Numerous recovery measures implemented since listing have improved the conservation status of Borax Lake chub and protection of its habitat (Williams and Macdonald 2003). When the species was listed, critical habitat was designated on 259 hectares of land surrounding the lake, including 129 hectares of public lands and two 65- hectare parcels of private land. In 1983, the U.S. Bureau of Land Management designated the public land as an Area of Critical Environmental Concern. The Nature Conservancy began leasing the private lands in 1983 and purchased them in 1993, bringing the entire critical habitat into public or conservation ownership. The Nature Conservancy ended water diversion from the lake for irrigation and livestock grazing within the critical habitat. Passage of the Steens Mountain Cooperative Management and Protection Act of 2000 removed the public BLM lands from mineral and geothermal development within a majority of the basin. These actions, combined with detailed studies of the chub and their habitat have added substantially to our knowledge of the Borax Lake ecosystem (Scoppettone et al. 1995, Salzer 1992, Perkins et al. 1996). However, three primary threats remain. These include the threat to the fragile lake shoreline, wetlands, and soils from a recent increase in recreational use around the lake (particularly off-road vehicle usage), the threat of introduction of nonnative species, and potential negative impacts to the aquifer from geothermal groundwater withdrawal if groundwater pumping were to occur on private lands outside the protected areas (Williams and Macdonald 2003). Although an increase in abundance is not a goal in the successful recovery of this species, monitoring trends in abundance over time is an important management tool to assess species status. From 1998-2004, data describing the abundance of the Borax Lake chub population are not available. Abundance estimates were obtained from 1986- 1997 by The Nature Conservancy (Salzer 1997) (Figure 1). Abundance estimates for 1986-1990 are not comparable with those obtained in 1991-1997. Prior to 1991, estimates were obtained only from traps set around the perimeter of the lake. In 1991, estimates were obtained from traps set on a regularly spaced grid throughout the lake. A study comparing the methods suggests that prior to 1991 abundance was under estimated, perhaps by as much as 50 percent (Salzer 1992). A recent review of the conservation status of the Borax Lake chub by Williams and Macdonald (2003) cited the lack of recent and ongoing population and ecosystem monitoring as one argument against downlisting or delisting the species at this time. The chub population has experienced substantial fluctuations in abundance over the time period (1986-1997) when abundance data are available (Figure 1). At the time of the review, the most recent abundance estimates that were obtained in 1996 and 1997 were some of the lowest estimates since 1991. Borax Lake chub population abundance estimates from 1986 to 1997 and 2005 to 2006. Horizontal bars represent 95% confidence limits. In 1986-1990 (solid symbols), only the perimeter of the lake was trapped. After 1990 (open symbols) the entire lake was trapped. Estimates are not directly comparable across these time periods. There are limited data on population age structure that offer valuable insight into the productivity of Borax Lake chub. Williams and Bond (1983) examined lengthfrequency data and concluded that the population consisted primarily of age 1 fish, with few age 2 and age 3 fish present. Limited opercle bone aging of chub collected in 1992- 1993 also indicated that most Borax Lake were less than one year of age (67-79%), yet a few individuals were aged at 10+ years (Scoppettone 1995). Because Borax Lake chub are only found in one location and the population is apparently dominated by a single year-class of adults, the species has a high inherent risk of extinction. 3 The objectives of this study were to: 1) obtain a mark-recapture population estimate of Borax Lake chub, and 2) to evaluate ways to reduce handling of Borax Lake chub when monitoring population abundance both by modifying previous mark-recapture protocols and by developing snorkeling survey protocols to use as an alternative to mark-recapture estimates. In addition, we collected data regarding lake temperatures, chub size (age) structure, and the condition of the fragile lake shoreline and outflows. Title: 2006 Borax Lake Chub Investigations Progress Reports 2006 Abstract -- Borax Lake chub (Gila boraxobius) is represented by a single population that inhabits a 4.1 hectare geothermally-heated alkaline lake in Harney County, Oregon. The Borax Lake chub is a small minnow endemic to Borax Lake and adjacent wetlands in Oregon’s Alvord Basin (Williams and Bond 1980). Borax Lake is a natural lake, perched 10 meters above the desert floor on sinter deposits, which is fed almost exclusively by thermal groundwater. The Borax Lake chub was listed as endangered under the federal Endangered Species Act in 1982 (U.S. Fish and Wildlife Service 1982). Population abundance estimates obtained in 1991-1996 indicated a fluctuating population ranging from a low of 8,144 fish to a high of 34,634 fish (Salzer 1997). The basis for the Borax Lake chub’s listed status was not population size, but the security of a very limited, unique, isolated, and vulnerable habitat. Because Borax Lake is situated above salt deposits on the desert floor, alteration of the salt crust shoreline could reduce lake levels and the habitat quantity and quality available to Borax Lake chub. At the time of the listing, Borax Lake was threatened by habitat alteration caused by geothermal energy development and alteration of the lake shore crust to provide irrigation to surrounding pasture lands. The Borax Lake chub federal recovery plan, completed in 1987, advocated protection of the lake ecosystem through the acquisition of key private lands, protection of groundwater and surface waters, controls on access, and the removal of livestock grazing (U.S. Fish and Wildlife Service 1987). Numerous recovery measures implemented since listing have improved the conservation status of Borax Lake chub and protection of its habitat (Williams and Macdonald 2003). When the species was listed, critical habitat was designated on 259 hectares of land surrounding the lake, including 129 hectares of public lands and two 65- hectare parcels of private land.
