Durham Irrigation Dam Removal & Roughened Channel Installation
The factors limiting fish passage and habitat degradation at the Durham Irrigation Dam restoration site were the result of an obsolete irrigation diversion dam. This site is located at river mile five on Toppenish Creek. During periods of heightened instream flows, the confines of the dam abutments created a hydraulic pressure gradient, limiting successful fish passage.
LaSalle High School Fish Habitat Improvement & Floodplain Enhancement
Yakama Reservation Watersheds Project staff completed a bank stabilization and floodplain restoration project in and adjacent to Ahtanum Creek. Anthropogenic and natural factors have led to the rapid erosion of three stream meanders, a discontinuity between the floodplain and the stream, and a domination of non-native invasive vegetation within the project site. Endangered Species Act listed species: Mid-Columbia River steelhead trout and bull trout, Chinook, and coho; utilize Ahtanum Creek for multiple life history stages.
Yakima Klickitat Fisheries Project (YKFP)
To restore sustainable and harvestable populations of salmon, steelhead, and other at-risk species, the YKFP is evaluating all stocks historically present in the Yakima and Klickitat Subbasins and, using principles of adaptive management, is applying a combination of habitat protection and restoration, as well as hatchery supplementation or reintroduction strategies to address limiting factors.
Status and Trends Annual Report
The Status and Trends Annual Report (STAR) Project summarizes fish population status and trends, habitat restoration action implementation, Yakama Nation production and reintroduction programs, and Federal mainstem hydrosystem improvements as they affect Yakama Nation treaty-trust aquatic species and their habitats.
Natural Production Restoration Project
Dramatic declines in the abundance of anadromous Pacific salmonids have occurred over the last century in the Columbia River basin. Population declines followed harvest, hydrosystem and watershed development, habitat loss and degradation, and reduced survival in freshwater, estuary, and marine environments. These declines are accompanied by greatly reduced levels of natural production due to an array of anthropogenic factors.
Yakama Nation Brownfields Project
The Yakama Nation's Fisheries Resource Management Program (FRMP) is tasked with managing and carrying out the deliverables for the Tribal Response grant.
Upper Klickitat River In-Channel and Floodplain Enhancement Project
Enhance instream habitat and water quality to benefit Middle Columbia steelhead and spring Chinook at three priority sites totaling 0.29 cumulative river miles. Work will involve reshaping and replanting 0.62 miles (cumulative) of bank and 2.1 acres of floodplain.
Klickitat Watershed Enhancement Project (KWEP)
The Klickitat Watershed Enhancement Project (KWEP) focuses on restoration, enhancement and protection of aquatic habitats in the Klickitat River and its tributaries to support native anadromous fish production.

Yakima Basin Sockeye Reintroduction
Four nursery lakes in the Yakima River Basin, which historically produced an estimated annual return of at least 200,000 sockeye, were removed from production in the early 1900s when irrigation storage dams were constructed without passage. The Yakama Nation is working with the U.S.
