Book Description
The Umatilla Sub-basin lies in north central Oregon State and is a tributary of the Columbia River. The Umatilla River and its major tributaries are home to a variety of salmonid species, including steelhead, bull trout, mountain whitefish, interior redband trout and three species of salmon. Changes in land and water use in the Umatilla Sub-basin have imperiled many of these stocks and driven all three salmon stocks extinct. The need for a screening process to rapidly characterize the sub-basin in terms of fish recovery is driven by the rapid decline of the remaining stocks and the poor returns of hatchery released salmon. The purpose of the Umatilla Sub-basin Assessment is to document the condition of the aquatic ecosystem of the watershed and establish the context for planning, monitoring and evaluation of restoration activities in the watershed. The goals are to gain an understanding of the aquatic ecosystem relative to the historic conditions, determine current risks to the aquatic ecosystem and identify conservation and restoration priority areas. The screening approach consists of three phases: a brief environmental history, a characterization the life history patterns and requirements for a group of key salmonids and a primary limiting factor characterization. Selection criteria for the key species consisted of a variety of economic, ecological and political concerns, including natural reproducing populations; the sensitivity of the species to similar aquatic conditions; and the amount of data available for the species. The limiting factor characterization followed from the life stage requirements for these species and focused on temperature and flow limitations in the seasonal use areas and migratory corridors. Based on the assessment it was possible to stratify the sub-basin into areas of biological importance based on key species distribution, life stage requirements and diversity. Determining the primary limiting factors to the life stages was more difficult because many of the potential limiting factors do not have threshold values associated with them. The limiting factor characterization did yield insight into flow and temperature limitations, but did not present a complete picture of the limitations these species face.

Book Description
The Umatilla Basin Natural Production Monitoring and Evaluation Project (UBNPMEP) is funded by Bonneville Power Administration (BPA) as directed by section 4(h) of the Pacific Northwest Electric Power Planning and Conservation Act of 1980 (P.L.96-501). This project is in accordance with and pursuant to measures 4.2A, 4.3C.1, 7.1A.2, 7.1C.3, 7.1C.4 and 7.1D.2 of the Northwest Power Planning Council's (NPPC) Columbia River Basin Fish and Wildlife Program (NPPC 1994). Work was conducted by the Fisheries Program of the Confederated Tribes of the Umatilla Indian Reservation (CTUIR). The UBNPMEP is coordinated with two Oregon Department of Fish and Wildlife (ODFW) research projects that also monitor and evaluate the success of the Umatilla Fisheries Restoration Plan. This project deals with the natural production component of the plan, and the ODFW projects evaluate hatchery operations (project No. 1990-005-00, Umatilla Hatchery M & E) and smolt outmigration (project No. 1989-024-01, Evaluation of Juvenile Salmonid Outmigration and Survival in the Lower Umatilla River). Collectively these three projects monitor and evaluate natural and hatchery salmonid production in the Umatilla River Basin. The need for natural production monitoring has been identified in multiple planning documents including Wy-Kan-Ush-Mi Wa-Kish-Wit Volume I, 5b-13 (CRITFC 1996), the Umatilla Hatchery Master Plan (CTUIR & ODFW 1990), the Umatilla Basin Annual Operation Plan, the Umatilla Subbasin Summary (CTUIR & ODFW 2001), the Subbasin Plan (CTUIR & ODFW 2004), and the Comprehensive Research, Monitoring, and Evaluation Plan (CTUIR and ODFW 2006). Natural production monitoring and evaluation is also consistent with Section III, Basinwide Provisions, Strategy 9 of the 2000 Columbia River Basin Fish and Wildlife Program (NPPC 1994, NPCC 2004). The Umatilla Basin M & E plan developed along with efforts to restore natural populations of spring and fall Chinook salmon, (Oncorhynchus tshawytsha), coho salmon (O. kisutch), and enhance summer steelhead (O. mykiss). The need for restoration began with agricultural development in the early 1900's that extirpated salmon and reduced steelhead runs (Bureau of Reclamation, BOR 1988). The most notable development was the construction and operation of Three Mile Falls Dam (TMD) and other irrigation projects which dewatered the Umatilla River during salmon migrations. CTUIR and ODFW developed the Umatilla Hatchery Master Plan to restore fisheries to the basin. The plan was completed in 1990 and included the following objectives which were updated in 1999: (1) Establish hatchery and natural runs of Chinook and coho salmon. (2) Enhance existing summer steelhead populations through a hatchery program. (3) Provide sustainable tribal and non-tribal harvest of salmon and steelhead. (4) Maintain the genetic characteristics of salmonids in the Umatilla River Basin. (5) Increase annual returns to Three Mile Falls Dam to 31,500 adult salmon and steelhead. In the past the M & E project conducted long-term monitoring activities as well as two and three-year projects that address special needs for adaptive management. Examples of these projects include adult passage evaluations, habitat assessment surveys (Contor et al. 1995, Contor et al. 1996, Contor et al. 1997, Contor et al. 1998), and genetic monitoring (Currens & Schreck 1995, Narum et al. 2004). The project's goal is to provide quality information to managers and researchers working to restore anadromous salmonids to the Umatilla River Basin. The status of completion of each of BPA's standardized work element was reported in 'Pisces'(March 2008) and is summarized.
