  Citation × Citation Citation Abstract Copy Title: Slate Creek Watershed Assessment Abstract -- The analysis was jointly conducted by the Applegate River Watershed Council (ARWC), Bureau of Land Management (BLM), and the Siskiyou National Forest. Accordingly, the assessment method was designed to fulfill obligations for the Oregon Watershed Enhancement Board and the Federal Guide to Watershed Analysis. Issues and key questions, developed by the federal agencies, ARWC, and landowners guide the content of this analysis. Key issues focus the assessment on the principle concerns of the Slate Creek Watershed. This watershed assessment is grouped into three main categories: Cultural and Social environment, Terrestrial environment, and the Aquatic environment. The cultural and social environment examines the historic and current human uses in the watershed. The terrestrial environment focuses on vegetation patterns, wildlife habitat and fire/fuel conditions. Fish habitat conditions, water quality and riparian zone function are discussed in the aquatic environment.

  Citation × Citation Citation Abstract Copy Title: Thomas Creek Mainstem Assessment Completion Report Abstract -- This project expands upon a year 2000 project (OWEB 99-543) that was designed to examine riparian and water quality impacts on aquatic invertebrate assemblages and fish diet in Thomas Creek. The initial project design was to sample water quality, fish, and invertebrates at nine sites along 30 river kilometers (R kms) of the stream; three in conifer dominated, three in mixed forest, and three in hardwood dominated riparian forest. Preliminary results suggested water quality conditions were similar throughout the 30 R kms and riparian vegetation composition was not associated with fish diet or invertebrate assemblage composition. Longitudinal patterns were weak and appeared to be driven by three upstream sites. Therefore we proposed to expand the survey area to include the entire stream open to anadromous fish migration (51 R kms). The fish diet portion of the project was discontinued because we were denied a sampling permit for ESA listed salmonids during 2001. Instead, we focused on broad-scale fish distribution and habitat use. Additionally, we compared patterns for fish with invertebrates. The extent of fish, invertebrate, and water quality sampling locations increased to include all 51 R kms downstream of the waterfall. An extensive fish survey to examine fish distribution included 218 survey locations throughout the 51 R kms. Intensive snorkel surveys to examine fine-scale, habitat use by salmonids included four sample locations in the upstream 14 R kms. Invertebrate samples were collected from three habitat types at 27 sites to examine distribution and habitat use along the 51 R kms Title: Thomas Creek Mainstem Assessment Completion Report Abstract -- This project expands upon a year 2000 project (OWEB 99-543) that was designed to examine riparian and water quality impacts on aquatic invertebrate assemblages and fish diet in Thomas Creek.

  Citation × Citation Citation Abstract Copy Title: MidCoast A - Rapid Bio-assessment 1998 Midcoast Abstract -- Snorkel surveys were conducted in five midcoast watersheds that included the Yachats, Alsea, Yaquina, Siletz, and Salmon Rivers. These surveys were commissioned by the Midcoast Watershed Council, using funds granted by GWEB. The intent of these surveys was to begin to develop a base line for monitoring trends in the distribution and abundance of juvenile Coho, Steelhead and Cutthroat in Midcoast watersheds. Adult Coho escapement for many of these basins has hovered near all time low levels for multiple brood cycles. These surveys intend to identify the core areas within these basins that, at low spawner densities, provide suitable spawning habitats. They also intend to identify areas important for juvenile salmonid rearing such that restoration activities can focus on recovering reaches that adult salmonids are returning to.

  Citation × Citation Citation Abstract Copy Title: Limiting Factors Assessment and Restoration Plan for Steer Creek Tributary of Rock Cr Siletz Abstract -- This document provides watershed restoration actions proposed to enhance the Coho Salmon population within the Steer Cr. 6th field in Lincoln County, Oregon. This stream is a 4th order contributor to Rock Creek, which joins the Siletz River near Logsden, Oregon. The stream has been prioritized for restoration by the Midcoast Watershed Council because it appears to provide the best remaining spawning and rearing potential within the Rock Cr. basin. The report contains information on the physical setting, current status of Coho, resources used in developing the plan, general questions that guided the assessment, pre-survey mapping/location of habitat subdivisions, secondary branch habitats, critical contributing areas, lowland area, summer and winter habitat assessment, lake habitat, location of other resources, juvenile Coho, evaluation of habitat quality and Coho production, Field Assessment, location of potential migration barriers, potential sites for restoration work, morphology, rank of restoration efforts, riparian corridor, and core area.

  Citation × Citation Citation Abstract Copy Title: Clear and Foster Creek Watershed Assessment Abstract -- A watershed assessment was completed in the Clear and Foster Creek watersheds to evaluate existing conditions and make recommendations to protect or enhance watershed natural resources. Clear and Foster Creek are tributaries to the Clackamas River below any major dams on the system; consequently these tributaries are positioned favorably to contribute to recovery of important anadromous fish populations. Anadromous fish species in the Clackamas basin include spring and fall chinook, coho salmon, winter steelhead, summer steelhead (non-native), migratory cutthroat trout and lamprey. Clear and Foster Creeks are utilized by fall chinook, winter steelhead and coho salmon. The assessment generally followed the framework described in the Oregon Watershed Enhancement Board’s Watershed Assessment Manual (WPN, 1999). The assessment focused on the following components: Channel habitat classification and modification; hydrology and water use; riparian/wetlands; sediment sources; water quality; fisheries; and wildlife and upland vegetation. Generally the approach builds on existing information, and enhances this information with aerial photo interpretation and limited field checking. Additional fieldwork was used to verify channel habitat types and to characterize fish habitat condition. GIS was used as a critical assessment tool and method of displaying results.
