  Citation × Citation Citation Abstract Copy Title: Oregon Chub Investigations, Progress Report 2001 Abstract -- Populations of Oregon chub Oregonichthys crameri, endemic to the Willamette Valley, have been drastically reduced. Factors in the decline of this fish include changes in flow regimes and habitat characteristics resulting from the construction of flood control dams, revetments, channelization, diking, and the drainage of wetlands. The Oregon chub is further threatened by predation and competition by non-native species such as largemouth bass Micropterus salmoides, small mouth bass M. dolomieui, crappies Pomoxis sp., sunfishes Lepomis sp., bullheads Ameiurus sp., and western mosquitofish Gambusia affinis. We surveyed in the Willamette River drainage in April-October 2000 to quantify existing Oregon chub populations, search for unknown populations, evaluate potential introduction sites, and monitor introduced populations. We sampled a total of 77 sites in 2000. We collected Oregon chub for the first time from Barnard Slough in the Middle Fork Willamette drainage. Oregon chub were last collected from this location in 1983 (Bond 1984). Thirty-one of the 77 sites were new sites that were sampled for the first time in 2000. Forty-six sites, sampled in 1991-1999, were revisited. Three sites were sampled twice. We confirmed the continued existence of Oregon chub at 20 locations. These include naturally occurring populations in the Santiam drainage (Geren Island, Santiam Conservation Easement, Gray Slough, Santiam 1-5 backwaters, Pioneer Park backwater, Santiam Public Works Pond), Mid-Willamette drainage (Finley Gray Creek Swamp) and Middle Fork Willamette drainage (Dexter Reservoir Alcoves, East Fork Minnow Creek Pond, Shady Dell Pond, Buckhead Creek, Oakridge Slough, Elijah Bristow State Park, Rattlesnake Creek, and Hospital Pond) and introduced populations in the Middle Fork Willamette (Wicopee Pond, Fall Creek Spillway Ponds), Santiam (Foster Pullout Pond), and Mid-Willamette drainages (Dunn Wetland, Finley Display Pond). Oregon chub were not found at several locations (Jasper Park Slough, Wallace Slough, East Ferrin Pond, Dexter East Alcove, Hospital lmpoundment Pond, Logan Slough, Green's Bridge Backwater, Camas Swale) where they were collected on at least one occasion between 1991-1999 (Scheerer et. al. 1992; 1993; 1994; 1995; 1996; 1998; 1999; 2000; Scheerer and Jones 1997). Non-native fish were common in off-channel habitats that were surveyed in the Willamette River drainage. Non-native fish were collected from 23 of the 31 new sites sampled in 1999 (74%); no fish were collected at three locations (10%). Western mosquitofish and centrarchids (largemouth bass and bluegill) were the most common non-native fish collected. Oregon chub were introduced into Menear's Bend Pond in the Santiam River drainage in the October 2000. Additional Oregon chub were introduced into Foster Pullout Pond in October 2000, to supplement the 85 fish introduced in 1999. In the summer of 2000, a habitat enhancement project creating new habitat to benefit Oregon chub was completed in the Long Tom drainage (Mid-Willamette River). Seven potential Oregon chub reintroduction sites were monitored and evaluated. These included four sites in the Mid-Willamette River drainage (Finley National Wildlife Refuge Beaver and Cattail Ponds, Ankeny National Wildlife Refuge Dunlin-Woodduck Pond, Long Tom Ranch Pond), one site in the Santiam River drainage (Menear's Bend Pond), one site in the McKenzie River drainage (Russell Pond), and one site in the Coast Fork Willamette drainage (Layng Pond). Estimates of abundance were obtained for naturally occurring populations of Oregon chub in East Fork Minnow Creek Pond, Shady Dell Pond, Elijah Bristow State Park Sloughs, Hospital Pond, Dexter Reservoir Alcoves, Buckhead Creek, Oakridge Slough, Santiam Conservation Easement Sloughs, Geren Island Ponds, and Finley Gray Creek Swamp. Five of these populations showed an increase in abundance in 2000 (East Fork Minnow Creek Pond, Shady Dell Pond, Middle Buckhead Creek, Dexter Reservoir Alcoves, Finley Gray Creek Swamp). Four populations decreased in abundance (or remain depressed) in 2000 (Geren Island, Santiam Conservation Easement, Elijah Bristow Sloughs, Oakridge Slough) (Table 1 ). Abundance estimates for introduced populations of Oregon chub were also obtained. The Oregon chub population in East Ferrin Pond declined from 7,200 fish in 1997 to O fish in 2000, and is presumed extinct. The Oregon chub population in the Fall Creek Spillway Pond totaled 5,030 fish in 2000, compared to 6,300 fish in 1999. The Oregon chub population in Wicopee Pond expanded dramatically from ~50 fish in 1999 to 4,580 fish in 2000. The Oregon chub population in the Dunn Wetland Ponds increased from 4,860 fish in 1999 to 14,090 fish in 2000. The Oregon chub population in Finley Display Pond increased from 360 fish in 1999 to 1,750 fish in 2000. Three of the four largest populations in 2000 were introduced populations. The Middle Fork Willamette River drainage supported the largest number of Oregon chub populations (n=12), followed by the Santiam drainage (n=B), and the Mid-Willamette drainage (n=5). The most abundant Oregon chub populations were found in the Middle Fork Willamette and Mid-Willamette drainages. The Oregon Chub Recovery Plan (U .S. Fish and Wildlife Service 1998) set a recovery goal for downlisting the species to "threatened" and for delisting the species. The criteria for downlisting the species was to establish and manage ten populations of at least 500 adult fish. All populations must exhibit a stable or increasing trend for five years. At least three populations must be located in each of the three sub-basins (Middle Fork Willamette River, Santiam River, Mid-Willamette River tributaries). In 2000, there were 11 populations totaling 500 or more individuals and six of these populations exhibited a stable or increasing trend for the past five years (Table 1 ). Five of these six populations were located in the Middle Fork Willamette drainage. In summary, Oregon chub remain at risk due to their limited distribution compared with their historic geographic range in the Willamette Valley, the loss of suitable habitat and the continued threats posed by the proliferation of non-native fishes, illegal water withdrawals, unauthorized fill and removal operations, and potential chemical spills or careless pesticide applications.

  Citation × Citation Citation Abstract Copy Title: Progress Reports 2004: 2004 Oregon Chub Investigations Abstract -- Oregon chub are endemic to the Willamette River drainage of western Oregon (Markle et al. 1991). This species was formerly distributed throughout the Willamette River Valley (Snyder 1908) in off-channel habitats such as beaver ponds, oxbows, stable backwater sloughs, and flooded marshes. These habitats usually have little or no water flow, have silty and organic substrate, and have an abundance of aquatic vegetation and cover for hiding and spawning. In the last 100 years, off-channel habitats have disappeared because of changes in seasonal flows resulting from the construction of dams throughout the basin, channelization of the Willamette River and its tributaries, and agricultural practices. This loss of habitat combined with the introduction of non-native species to the Willamette Valley resulted in a sharp decline in Oregon chub abundance. The reduction of habitat and the restricted distribution of the Oregon chub resulted in a determination of "endangered" status under the federal endangered species act (Markle and Pearsons 1990; Rhew 1993). To evaluate Oregon chub population abundance and distribution, the Oregon Department of Fish and Wildlife conducted surveys in April-October 2004. We conducted similar surveys in 1991-2003 (Scheerer et. al. 1992; 1993; 1994; 1995; 1996; 1998; 1999; 2000; 2001; 2002; 2003; 2004; Scheerer and Jones 1997). The survey objectives were to collect information on the status, distribution, and abundance of Oregon chub, the presence of non-native and native species, the characteristics of Oregon chub habitats, the characteristics of potential introduction sites, and to evaluate the success of Oregon chub introductions. In addition, we reviewed and evaluated projects and activities with the potential to impact Oregon chub and their habitats and provided summaries to the U.S. Fish and Wildlife Service.

These plans guide the development of localized plans for species management units, and individual river basins. A fish management plan was adopted by the OFWC in 1997 for the Klamath River Basin. Basin fish management plans serve several functions. They present a logical, systematic approach to conserving our aquatic resources; establish management priorities, and direct attention to the most critical problems affecting our fisheries. In November 2002, the OFWC adopted the Native Fish Conservation Policy (NFCP) that calls for development of conservation plans for each species management unit to ensure conservation and recovery of native fishes in Oregon. Intent of the NFCP is to provide a basis for managing hatcheries, fisheries, habitat, predators, competitors, and pathogens in balance with sustainable production of naturally produced native fish. The policy has three areas of emphasis. The first is defensive, to ensure avoidance of serious depletion of native fish. The second is more proactive, to restore and maintain native fish at levels providing ecological and societal benefits. The third area of emphasis ensures that, consist with native fish conservation, opportunities for fisheries and other societal resource uses are not unnecessarily constrained. The NFCP acknowledges that basin fish management plans will provide fish management guidance until conservation plans can be completed.

  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: Tenmile Lake Basin Partnership - OWEB Final Report: Grant 217-2051 Abstract -- Pacific Lamprey are native to the Tenmile Watershed and culturally important to the local Native American Tribes. Likewise, Salmon and Steelhead have both an economic and cultural significance to the local citizens and Tribes. Pacific Lamprey were historically harvested by the people of the Confederated Tribes of the Coos, Lower Umpqua and Siuslaw Indians (CTCLUSI), but it was unknown if Pacific Lamprey were still present in the Tenmile Watershed. A fish trap was built on Eel Lake by the Oregon Department of Fish and Wildlife (ODFW) in 1989 for the purpose of fish capture and rearing. The trap is effective in capturing Salmon and Steelhead but may act as a barrier to the passage of Pacific Lamprey. This monitoring effort was designed to assess the presence/absence of Pacific Lamprey in the Tenmile Watershed, identify migration timing, potential lamprey passage barriers and rearing/spawning habitats, and collect and organize data from Eel Lake Trap on native Coho, Cutthroat, and native/hatchery Steelhead returns and trends. Lamprey larvae (ammocoete) monitoring was conducted in the summer of 2017 using electro-shockers. Shocking occurred on 3 tributaries of Tenmile Lakes (Big Creek, Johnson Creek, and Shutter Creek), and 3 creeks within the Eel Lake basin (Eel Creek, Clear Creek, and Winters Arm Creek). Two species of lamprey were identified, Western Brook (Lampetra richardsoni) and Pacific (Entosphenus tridentatus). Western Brook were found in all sampled Tenmile Lakes Basin streams, but only in the streams above Eel Lake Trap in the Eel Lake Basin. No Western Brook were identified in Eel Creek below the Trap. Pacific Lamprey were found in Johnson Creek and Big Creek in the Tenmile Lakes Basin, and in Eel Creek in the Eel Lake Basin. No Pacific Lamprey were identified above the Eel Lake Trap, suggesting that it may act as a complete passage barrier to that species. In addition, over 200 adult Pacific Lamprey were salvaged from an ODOT culvert enhancement project on Eel Creek near Hwy 101. Pacific Lamprey larvae were identified upstream of this project, but it is likely that it was a partial barrier. Two other ODOT culverts were identified as potential partial lamprey barriers on Eel Cr. Spawning areas for Pacific and Western Brook Lamprey are similar to spawning areas for salmon. Upper reaches of all the Tenmile Lake tributaries have appropriate spawning gravel. Lower stream areas are often high in sediment which is conducive to rearing lamprey larvae. This was confirmed in Johnson creek with high numbers of Pacific Lamprey larvae found at the mouth as it enters South Tenmile Lake. Farther upstream in the Johnson Creek system, larvae were abundant, but much smaller with many being too small to identify (<65mm). Western Brook larvae were found, but no Pacific Lamprey larvae were identified, perhaps amongst those unidentified specimens. Western Brook ammocoetes were also found at the lower site on Johnson Creek, and in Big Creek and Shutter Creek. Pacific Lamprey migration into the watershed is difficult to determine due to the elusive nature of the species and their life cycle trait of migrating in from the ocean in the spring of one year, then holding over until the next spring before spawning. When specimens are captured, it is difficult to determine whether it is a fresh migrant or last year’s holdover. Even if it can be determined which year it is from, it is still difficult to know how long it has been in the system before it was captured. In Phase 2 of this project, we will capture Pacific Lamprey either in traps near the mouth of Eel Cr, or at the lower culverts. This should give us a better sense of migration timing. Native Coho salmon counts at Eel Lake Trap were down significantly from the recorded high at the Trap of 441 in 2012, with only 66 native Coho returning in 2018 (the winter of 2017-2018). The previous 2 years were also low with 2016 and 2017 showing returns of only 53 and 118 respectively. The Coho numbers for most of the Oregon Coast also showed low returns. Hatchery Winter Steelhead counts were 502 for 2018. This compares to a record high of 828 in 2007, 595 in 2016, and 226 in 2017. Returning native Steelhead only numbered 10 for the 2018 season. The average return for Native Steelhead is 24. In 2018, 60 Steelhead were spawned including 2 native males, but no native females. 252 hatchery Steelhead were recycled into Saunders Lake, and 148 into Butterfield Lake. ODFW allocated 25,000 smolts for the Tenmile Watershed, which were acclimated and then released in April 2018.

No Pacific Lamprey were identified above the Eel Lake Trap, suggesting that it may act as a complete passage barrier to that species. In addition, over 200 adult Pacific Lamprey were salvaged from an ODOT culvert enhancement project on Eel Creek near Hwy 101. Pacific Lamprey larvae were identified upstream of this project, but it is likely that it was a partial barrier. Two other ODOT culverts were identified as potential partial lamprey barriers on Eel Cr. Spawning areas for Pacific and Western Brook Lamprey are similar to spawning areas for salmon. Upper reaches of all the Tenmile Lake tributaries have appropriate spawning gravel. Lower stream areas are often high in sediment which is conducive to rearing lamprey larvae. This was confirmed in Johnson creek with high numbers of Pacific Lamprey larvae found at the mouth as it enters South Tenmile Lake. Farther upstream in the Johnson Creek system, larvae were abundant, but much smaller with many being too small to identify (<65mm). Western Brook larvae were found, but no Pacific Lamprey larvae were identified, perhaps amongst those unidentified specimens. Western Brook ammocoetes were also found at the lower site on Johnson Creek, and in Big Creek and Shutter Creek. Pacific Lamprey migration into the watershed is difficult to determine due to the elusive nature of the species and their life cycle trait of migrating in from the ocean in the spring of one year, then holding over until the next spring before spawning. When specimens are captured, it is difficult to determine whether it is a fresh migrant or last year’s holdover. Even if it can be determined which year it is from, it is still difficult to know how long it has been in the system before it was captured. In Phase 2 of this project, we will capture Pacific Lamprey either in traps near the mouth of Eel Cr, or at the lower culverts. This should give us a better sense of migration timing. Native Coho salmon counts at Eel Lake Trap were down significantly from the recorded high at the Trap of 441 in 2012, with only 66 native Coho returning in 2018 (the winter of 2017-2018). The previous 2 years were also low with 2016 and 2017 showing returns of only 53 and 118 respectively. The Coho numbers for most of the Oregon Coast also showed low returns. Hatchery Winter Steelhead counts were 502 for 2018. This compares to a record high of 828 in 2007, 595 in 2016, and 226 in 2017. Returning native Steelhead only numbered 10 for the 2018 season. The average return for Native Steelhead is 24. In 2018, 60 Steelhead were spawned including 2 native males, but no native females. 252 hatchery Steelhead were recycled into Saunders Lake, and 148 into Butterfield Lake. ODFW allocated 25,000 smolts for the Tenmile Watershed, which were acclimated and then released in April 2018. Close

  Citation × Citation Citation Abstract Copy Title: Abundance, Productivity, and Life History of Fifteenmile Creek Steelhead; Annual Report 2016 Abstract -- The Fifteenmile Creek watershed in North Central Oregon hosts a native population of steelhead (Oncorhynchus mykiss) that is without influence of previous hatchery augmentation. The Fifteenmile Creek steelhead are a subpopulation within the Distinct Population Segment (DPS) of the Middle Columbia River steelhead and was listed as ‘threatened’ by the National Marine Fisheries Service (NMFS) first on March 25, 1999 and relisted as a DPS on January 5, 2006. Subsequently, a conservation and recovery management plan was developed for the Middle Columbia River steelhead DPS within Oregon state borders. The goal of the plan is to recover Middle Columbia River steelhead to a level that would allow the removal of threatened status, in addition to providing a long-term goal to recover the population sufficiently to provide sustainable fisheries and other ecological, cultural, social and economic benefits for future generations. The DPS-level recovery plan sets specific recovery goals for the areas within the DPS, which designates Fifteenmile Creek explicitly. The Fifteenmile Creek steelhead population is considered the most inland winter race of steelhead in the Columbia River Basin, as designated by NOAA fisheries. However review of this designation may be necessary at the next Federal Columbia River Power System (FCRPS) Biological Opinion (BiOp) status-review because the run-timing of adult steelhead passing Bonneville Dam has been inconsistent with known winter-run steelhead in the area. The population was identified as “must have viable” status by the Interior Columbia Technical Recovery Team (ICTRT), and reaching viable status is essential for achieving DPS delisting. The ICTRT, Recovery Plan, and the Federal Columbia River Power System (FCRPS-BiOp) have all identified this population as high priority for improving precision and accuracy of abundance, productivity, diversity, and spatial structure information.

  Citation × Citation Citation Abstract Copy Title: Escapement and Productivity of Summer Steelhead and Spring Chinook Salmon in the John Day River; Annual Report 2017 Abstract -- The John Day River, located in northeastern Oregon, supports five wild populations of summer steelhead (Oncorhynchus mykiss) and three populations of wild spring chinook (Oncorhynchus tschawytscha) with no hatchery supplementation. However, these populations remain depressed relative to historic levels. In 1999, the National Marine Fisheries Service (NMFS) listed the Middle Columbia River summer steelhead Distinct Population Segment (DPS), which includes the John Day River Major Population Group (MPG), as threatened under the Endangered Species Act (ESA). Although numerous habitat protection and rehabilitation projects have been implemented within the John Day River basin to improve steelhead and other salmonid freshwater production and survival, it has been difficult to estimate the effectiveness of these projects without a systematic program in place to collect information on the status, trends, and distribution of spawning activity, juvenile salmonids, and aquatic habitat conditions within the basin. Prior to the inception of this project, population and environmental monitoring of steelhead in the basin consisted of a combination of index spawning surveys and periodic monitoring of some status and trend indicators. While index spawning data is useful for drawing inference about long-term trends in adult steelhead abundance, they are limited for determining the status of steelhead escapement or distribution at the population or MPG scale because survey sites are not randomly selected and are likely biased towards streams with higher fish abundance. A broader approach to the monitoring and evaluation of status and trends in anadromous and resident salmonid populations and their habitats was needed to provide data to effectively support restoration efforts and guide alternative future management actions in the basin. The Independent Scientific Review Panel (ISRP) recommended that the region move away from index surveys and embrace probabilistic sampling for most population and habitat monitoring. To meet the ISRP recommendation, the structure and methods employed by the Oregon Plan for Salmon and Watersheds Monitoring Program were extended to the John Day basin. This approach incorporates the sampling strategy of the United States Environmental Protection Agency’s (EPA) Environmental Monitoring and Assessment Program (EMAP). This research effort employs a statistically based and spatially explicit sampling design to answer key monitoring questions, integrate on-going sampling efforts, and improve agency coordination. The current program seeks to integrate project objectives focused on summer steelhead spawning metrics, juvenile salmonid metrics, and aquatic habitat conditions.

  Citation × Citation Citation Abstract Copy Title: McKenzie River Plan Summary, Mailing Abstract -- The McKenzie River subbasin is an area rich in natural beauty and resources. The tradition of fishing the McKenzie runs deep, and its notoriety reaches far and wide. The McKenzie River is one of the most popular rivers for fishing in Oregon. During the 1983 trout season, an estimated 54,000 anglers fished from Blue River to Armitage Park. The most sought after species include native rainbow and cutthroat trout, spring chinook, and in recent years, an introduced run of summer steelhead. To meet angling demand, hatchery rainbow trout are stocked in portions of the mainstem, Blue River, and the South Fork. During the past year, Oregon Department of Fish and Wildlife biologists and a public advisory team from the McKenzie River/Eugene-Springfield area, jointly developed a draft plan to guide the management of the fisheries in the McKenzie subbasin. The draft plan includes management guidelines, objectives, priorities, and recommended actions to solve the principal fisheries' problems concerning: • Habitat • Management of major fish species or groups of species • Angling access This summary covers some of the key elements of the draft plan.

Generally stated, the problem is that our coho salmon populations have slumped to the level we had almost 20 years ago after an apparently successful hatchery program had increased them to a record high in 1976. There is no simple explanation for, or solution to, the coho production problem. If we want to obtain a permanent increase in coho abundance, we must develop an organized and well-founded-program to lead us there. That is why we need a plan. A plan is like a map-it shows us how to get from one place to another. We are at a point of low coho abundance, and we want to get back to the level of abundance we enjoyed in the early 1970's. Production is not Oregon's only coho problem. There are many other issues dealing with allocation, harvest, stocks, surplus fish, escapements, habitat, etc. (see lA). Most of these are interrelated, and many are a part of the coho production problem. Although these are all important considerations in the development of Oregon's coho management plan, the coho production problem has been emphasized.

  Citation × Citation Citation Abstract Copy Title: Umpqua Fish Management District Guide to Restoration Site Selection Abstract -- Research in Oregon coastal areas indicates there is potential to improve the productive capacity of freshwater rearing streams, principally by improving the quality of over-winter rearing habitat for juvenile salmonids. The objective of this document is to identify stream reaches where habitat restoration work may improve the status of anadromous salmonids. This document also represents a contribution to the Oregon's Coastal Salmon Restoration Initiative. In this report, we identify stream reaches in the Umpqua basin with habitat restoration potential. We also discuss selection of appropriate restoration techniques. The list of potential restoration reaches was compiled based on analysis of Aquatic Habitat Inventory Data and recommendations of ODFW biologists. Our work is designed to complement ongoing habitat protection and restoration efforts by ODFW personnel. The selected reaches may be suitable for various instream and riparian-zone restoration activities specific to perceived limiting factors, thereby increasing capacity to produce salmonids. The reaches have relatively low gradient (<5%), moderate active channel width (3-12 m), and are within relatively broad valleys. These physical characteristics offer the highest potential capacity to support juvenile anadromous fish. The proposed work is intended to help restore natural stream and riparian processes to a condition that will support more production of anadromous fish than is currently possible. Data from almost 1,200 stream reaches were screened to identify the 215 potential restoration sites described in this report. The sites are primarily on private industrial timberlands. A full description of each potential restoration site was limited by our timetable. As work proceeds on these reaches in the future, prioritization of current sites and identification of additional restoration reaches will occur. In guides prepared for other basins, the sites or reaches were presented as "probably suitable" for restoration activities to begin immediately. In this guide, however, we could not reduce the list to those sites appropriate for immediate project design. Consequently, the reaches described should be evaluated further before making any commitments to project design. An approach to further evaluation of the proposed restoration sites is described in this report.

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.

The species was listed as sensitive by the U.S. Forest Service Region 6 and Bureau of Land Management and by the State of Oregon. Recent surveys suggested Pit Sculpin have a restricted range in Oregon. The objectives of our surveys were to: 1) describe the current distribution and estimate the abundance of Pit Sculpin in Drews and Camp creeks, 2) describe the fish assemblages in Drews and Camp creeks, and 3) describe stream habitat conditions and collect habitat covariate data at each sampling location for modelling capture probabilities and abundance. We found Pit Sculpin distribution was limited to approximately 5.2 km of Drews Creek and 0.8 km of Camp Creek. Pit Sculpin primarily occupied riffles with gravel substrate. We estimated 12,331 and 1,518 Pit Sculpin in Drews and Camp creeks, respectively.

The effort encompassed all of the mainstem and tributary habitats, upstream of the Holley Bridge (USGS RM 45.5). Tributary inventories extended to the end of significant rearing potential for anadromous salmonids. In addition, a spring chinook resting count inventory encompassing the same mainstem reach and an additional 9.5 miles downstream to the deconstructed Brownsville Dam site (USGS RM36) was conducted in an attempt to quantify the abundance of adult Spring Chinook returning to the basin to spawn. An inventory of spawning gravel abundance was also conducted in the 30 miles of mainstem and tributary stream habitats exhibiting any anadromous potential (only spawning gravel sites appropriate for steelhead were quantified). Title: 2015 Calapooia River Rapid Bio-Assessments Inventory Abstract -- The 2015 Rapid Bio-Assessment inventory of the Calapooia basin covered 37.2 miles of stream habitat. The effort encompassed all of the mainstem and tributary habitats, upstream of the Holley Bridge (USGS RM 45.5).

Abstract -- Knowledge of fish movements and residency are key to design and interpretation of results from bioacoustic sonar and visual survey methods, which are being developed as tools for use in nearshore rocky reef surveys to estimate biomass and species composition. Fishers in Oregon report that an important component of the nearshore catch, Deacon Rockfish (Sebastes diaconus), become unavailable to harvest seasonally, and suggest periodic migration away from nearshore reef areas. Seasonal and spatial variation in landings data potentially support this theory. We used a high-resolution acoustic telemetry array and a combination of presence/absence receiver arrays, to study the daily and seasonal movements and the activity patterns of 11 acoustically tagged Deacon Rockfish on a nearshore rocky reef off Seal Rock, Oregon. Over the 11-month study period, most fish (n=6) exhibited high site fidelity. For the duration of the high-resolution array (5 mo), these fish had small home ranges (mean 95% KDE=4907 m2) and consistent activity patterns, except during seasonal hypoxia (defined as dissolved oxygen concentration [DO] < 2 mg l-1). During the summer months, resident fish were strongly diurnal with high levels of daytime activity above the bottom in relatively rugose habitat, followed by nighttime rest periods in deeper water in habitat of relatively less rugosity. During hypoxia, fish exhibited moderate activity levels with no rest periods and moved well away from their core activity areas on long, erratic forays. Wintertime activity levels were moderate with less defined daily patterns, but fish continued to remain within the array area. We suggest that Deacon Rockfish remain on nearshore reefs throughout the year, but their visual capabilities and prey preferences for seasonally occurring planktonic organisms strongly influences their catchability. Habitat use and activity patterns exhibited by Deacon Rockfish are conducive to bioacoustic sonar and visual survey methods if season, daylight, and oxygen levels are considered.
