  Citation × Citation Citation Abstract Copy Title: Lower Umpqua Watershed Analysis, 1997 Abstract -- This analysis of the Lower Umpqua River watershed (2% of the total Umpqua River drainage area) in the southern Coast Range includes watershed characterization, issues, inherent landscape instability, aquatic species' habitat and population, terrestrial species' habitat and population, and restoration opportunities. This analysis was conducted by Siuslaw National Forest personnel with assistance from the Bureau of Land Management - Coos Bay District. The analysis was focused on fisheries and wildlife issues. The existing resource conditions were compared to expected natural conditions to assess trends in resource conditions. From this information, a strategy of restoration opportunities to enhance resource conditions on federal lands was developed. Watershed Analysis is one of the key components of the Aquatic Conservation Strategy (ACS) developed for the Northwest Forest Plan (NFP) (USDA-USDI 1994). The analysis is intended to facilitate watershed planning that: 1) achieves Aquatic Conservation Strategy and Late-Successional Reserve objectives and 2) provides the basis for monitoring and restoration programs.

  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: Douglas County Lakes and Reservoirs Master Plan for Angler Access and Associated Recreational Uses 1968 Abstract -- Douglas County covers roughly 5,000 square miles of Southwest Oregon and is almost coincidental with the boundaries of the Umpqua River watershed. The topography consists of the Coast Range mountains in the west, a central valley area and the Cascade Mountains to the east. Other valley areas are scattered throughout the county. Most of the lakes and impoundments of the county are located in the Cascades to the west and along the coast to the east. While good roads link these lakes with the populated areas of the county, additional developments are needed on about 30 lakes to spread out tourist pressure and help provide quality recreation over more of the county. A few of the larger more popular lakes are crowded to and beyond capacity during the trout season. Potential impoundments for recreation have been recommended at 23 sites. A high priority is placed on establishing warm-water fisheries adjacent to communities where heavy utilization favors better fish growth. Old log-ponds are sometimes used to good advantage for this type of recreation. This report details a plan that we hope can be followed to solve the access problems of the Douglas County lakes and reservoirs.

These activities are coordinated under the Oregon Plan for Salmon and Watersheds and are part of a broader effort to monitor populations of salmonids in select Oregon coastal streams. Two objectives of this program are to estimate the abundance of returning adult salmonids and downstream-migrating juvenile salmonids, and estimate the marine and freshwater survival rates for coho salmon. This record provided catch summary reports from monitoring activities for the 2005-2006 run-year of returning adult fish and year 2006 out-migration of juvenile fish in the West Fork Smith River.

  Citation × Citation Citation Abstract Copy Title: Status of Winter Rearing Habitat in Four Coho Population Units_ODFW AQI Winter Report Final 2008 Abstract -- We described the status of habitat in four Oregon coastal coho salmon (Oncorhynchus kisutch) population units (Nehalem, Siuslaw, Coquille, South Umpqua) during winter 2007, estimated the potential winter rearing capacity of streams within those population units, and described the differences observed in stream habitat between winter and summer with emphasis on slow water and secondary channel habitats. Sample sites were randomly selected and spatially balanced within the distribution of coho salmon (juvenile and adult) in Oregon coastal watersheds south of the Columbia River. Twenty five sites were targeted within each of the four population units. Each survey was approximately 1000 m in length and adhered to protocols in Moore et al (2007). The Habitat Limiting Factors Model (HLFM) was used to estimate habitat capacity and quality for rearing juvenile coho. The HLFM predicted that the Nehalem and Siuslaw basins could support the highest density of juvenile coho, and the South Umpqua the least. Seasonal changes in habitat were similar to that reported in a previous study. Winter surveys facilitated the assessment of habitat status and estimating capacity because the surveys were conducted at the time when habitat is most limiting to survival of juvenile coho. Winter surveys were particularly valuable in capturing secondary channel and slow water habitat units such as beaver ponds and alcoves. We also performed a sensitivity analysis to determine the number of survey sites necessary to represent each population unit within the desired confidence range of 30% recommended in the Coho Conservation Plan. Twenty five target sites were not adequate to describe the winter parr capacity within a 95% confidence interval of +30% in each population unit. Confidence intervals of estimates of parr per km ranged from 34 to 60% and mean parr per m2 ranged from 20 to 45%.

  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.

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. Close

We also sampled dependent population blocks across three monitoring strata (North Coast, Mid Coast, and Mid-South Coast). Using a spatially balanced site selection process (Generalized Random Tessellation Stratification; GRTS) we surveyed 451 unique sites within the range of coho salmon spawning or rearing. With the exception of the 2014 survey year, habitat data were collected during winter conditions (February – March). Habitat sampled in 2014 occurred within the summer field season (June – September). We used a Habitat Limiting Factors Model (HLFM) to estimate habitat capacity for winter coho parr and the HabRate model to assess habitat quality for each surveyed stream reach. HLFM estimates were expanded based on the total coho distribution in each population. Based on the habitat data the HLFM predicted the Floras population could support the highest density of juvenile coho (1568 parr/km), while the streams in the Siltcoos watershed could support the least (290 parr/km). At the ESU-level, there was no detectable change of high quality rearing habitat (= 1850 parr/km) when compared to previous studies, but changes were observed among populations over the course of these survey years. We compared individual habitat metrics across populations, land use, geology, and between independent and dependent populations. While no significant differences were observed between independent and dependent populations, differences in habitat metrics were detected among individual populations, land use types, and geologies. In addition, we detected a difference in reproductive habitat quality (spawning and emergence) between both populations and land use types.

  Citation × Citation Citation Abstract Copy Title: Oregon Fish Passage Barriers Abstract -- The Oregon Fish Passage Barrier Data Standard (OFPBDS) dataset contains barriers to fish passage in Oregon watercourses. Barriers include the following types of natural or artificial structures: bridges, cascades, culverts, dams, debris jams, fords, natural falls, tide gates, and weirs. The OFPBDS dataset does not include structures which are not associated with in-stream features (such as dikes, levees or berms). Barriers are structures which do, or potentially may, impede fish movement and migration. Barriers can be known to cause complete or partial blockage to fish passage, or they can be completely passable, or they may have an unknown passage status. This dataset complies with version 1.1 of the OFBPDS data standard. New optional attributes have been added to describe fish passage barrier feature modifications, to describe supplementary information (via a comments field) and also to linear reference the barrier features to the National Hydrography Dataset. The OFPBDS dataset now contains over 40,000 barrier features from 19 separate sources including: Oregon Department of Fish and Wildlife (ODFW), Oregon Department of Transportation (ODOT), Oregon Department of Water Resources (OWRD), Oregon Department of Forestry (ODF), Oregon Watershed Enhancement Board (OWEB), Oregon Department of Land Conservation and Development (DLCD) US Bureau of Land Management (BLM), US Forest Service, Nez Perce Tribe, Benton SWCD, Washington county, Lower Columbia River Estuary Partnership and watershed councils representing the Rogue, Umpqua, Siuslaw, Santiam, Calapooia, Clackamas and Scapoose basins. The Data Steward obtained fish passage barrier data from multiple data originators between 2008 and 2015, collaborated with them to develop inclusion / exclusion criteria and dataset specific crosswalks for converting data from its original data structure to the structure of the OFPBDS. The data were then converted into the OFPBDS format and analyzed for duplication with existing OFPBDS barrier features. Where duplicates were identified, depending upon the scenario, one feature was either chosen over the other or in some cases attributes from different sources are combined. Source information is retained for each feature. The data were then loaded into the OFPBDS database. Barrier features were linear referenced (Framework Hydro only which is outside of the standard) and the corresponding optional attribute elements were populated. The data conversion, duplication reconciliation and linear referencing protocols are documented in the Oregon Fish Passage Barrier Data Management Plan. A separate dataset containing fish passage barrier features that have been completely removed or replaced (e.g. dam removals and culvert replacements) is published simultaneously with the OFPBDS dataset. The OFPBDS database is the most comprehensive compilation of fish passage barrier information in Oregon however, it does NOT represent a complete and current record of every fish passage barrier within the state. Efforts to address deficiencies in data currency, completeness and accuracy are ongoing and are often limited by lack of sufficient resources. Attributes (including key attributes such as fish passage status) are often unknown or incomplete. Consistency in attribution also varies among data originators. Field verification of barrier features and their attributes will be an important component to making this dataset current, comprehensive and accurate. Fish passage status is a key attribute. Many barrier features have an unknown passage status. For other features, the passage status may have changed since it was originally documented. Note that this metadata file is best viewed in ArcCatalog. Documentation for the OFPBDS can be found online at http://www.oregon.gov/DAS/EISPD/GEO/docs/bioscience/OregonFishPassageBarrierDataStandardv1dot1.pdf.
