Several watershed assessments have been completed for the Umatilla subbasin. These assessments together have addressed many of the resource issues in the subbasin. These issues include sediment delivery, fish production, landbird conservation, ecological processes, and forest management, among others. Some reports also cover public involvement and agency interactions with regard to implementation of management plans. An annotated list of these assessments is presented below.
Altman, B., and A. Holmes (2000a) Conservation Strategy for Landbirds in the Columbia Plateau of Eastern Oregon and Washington. Documents the history of habitat loss and existing conditions of habitats for landbirds in the Columbia Plateau of Oregon and Washington with restoration and conservation strategies targeting the long-term maintenance of healthy populations of native landbirds.
Altman, B., and A. Holmes (2000b) Conservation Strategy for Landbirds in the Northern Rocky Mountains of Eastern Oregon and Washington. Documents the history of habitat loss and existing conditions of habitats for landbirds in the Blue Mountains of Oregon and Washington with restoration and conservation strategies targeting the long-term maintenance of healthy populations of native landbirds.

Confederated Tribes of the Umatilla Indian Reservation; Oregon Department of Fisheries and wildlife; U.S. Department of Interior; National Marine Fisheries Service; U.S. Bureau of Reclamation; U.S. Forest Service. Proposes rehabilitation objectives that include increasing CRP, improving flow timing and quantity, hatchery production, passage improvements, trap and haul programs, screening of diversions, and habitat restoration.

Columbia River Inter-Tribal Fish Commission (1996b). Wy-Kan-Ush-Mi Wa-Kish-Wit: Spirit of the Salmon. Vol. II: Subbasin Plans. Specific subbasin breakdown for fish population status/goals, problems impacting fish, ongoing actions, and recommended actions including law enforcement, instream flow and passage, watershed management for water quality, riparian restoration, range management, forest management, mining impact reduction, and artificial production.
Confederated Tribes of the Umatilla Indian Reservation and Oregon Department of Fish and Wildlife (1990). Umatilla River Subbasin Salmon and Steelhead Production Plan, Pendleton. This plan provides the basis for production strategies, documents current and potential production, summarizes agency and tribal management efforts, goals, and objectives, and identifies problems, opportunities, and strategies. These include subbasin geology, climate, vegetation, water resources, land use, habitat protection needs, constraints, opportunities, and implementation.
Confederated Tribes of the Umatilla Indian Reservation (1984). Report contains prioritized site specific initiatives for rehabilitations of anadromous salmon and steelhead populations in the Umatilla subbasin. Includes fish reestablishment and habitat improvement recommendations developed through consensus among staffs of Confederated Tribes of the Umatilla Indian Reservation, Oregon Department of Fish and Wildlife, and the Umatilla National Forest.
Confederated Tribes of the Umatilla Indian Reservation (1999). Flow Needs for Salmonids and Other Aquatic Organisms in the Umatilla River. Addresses the quantity and quality of stream flow necessary for salmonid survival during all life history phases in the mainstem Umatilla River. Sets goals for flows to meet the established fish restoration goals. These goals include rearing, migration, and channel-maintenance, temperature, stream flow, water quality, and adaptive management.
Harris, R.M. and C.F. Clifton (1999), Upper Umatilla River Sediment Analysis American Water Resources Association, http://www.awra.org/proceedings/Montana99/Harris.index.htm. This report summaries beneficial uses of the Umatilla River and discusses water quality issues include developing TMDLs for sediment and temperature. The report analyzes 34 years of streamflow records and 11 years of suspended sediment records, to quantify the annual and seasonal sediment loads and the relationships between suspended sediment and discharge. They found: 1) high spatial and temporal variability in annual sediment loads between stations, and at the same station year to year, and 2) a lack of correlation between streamflow and sediment indication complex streamflow and sediment supply relationships. Recommendations include future analysis to evaluate the reliability of automatic fixed point sampling by collecting concurrent depth integrated samples; future analysis to determine the frequency of sampling needed to characterize the sediment parameters; and, adding bedload sampling to determine bedload contribution to total load.

U.S. Forest Service (1990). Forest Land and Resource Management Plan: Umatilla National Forest. This plan covers use and protection of forest resources, legislative requirements, and local, regional, and national issues and concerns about forest management. It is intended to guide management activities within the context of the availability and suitability of lands for resource management. It includes economic and social environment, society, recreation, research needs, response to concerns, management direction, and implementation.
