Yakima River Basin Water Storage Feasibility Study

Home | Reports/Documents | News Releases | Photos | Email List | Contact Us


In May 2003 the Bureau of Reclamation initiated the Yakima River Basin Water Storage Feasibility Study to examine the feasibility and acceptability of storage augmentation in the Yakima River basin. The additional water storage is to benefit threatened and endangered species, irrigated agriculture, and municipal water supply.

The study was authorized by Congress in 2003. In accordance with the authorization, the initial emphasis of the study evaluated the feasibility of the Black Rock Dam alternative. Then evaluation of other storage alternatives will occur as well as an environmental impact evaluation of all alternatives. The environmental evaluation will be an environmental impact statement and will be a joint document that combines a planning report and an environmental impact statement that complies with both National Environmental Policy Act and State Environmental Policy Act requirements.

Study Process and Timeline

Basic data and information generally common to storage alternatives will be collected, compiled, and analyzed. This includes: the identification of water supply needs for agriculture, fisheries, and municipal purposes; a determination of the current shortage of water supply to meet these needs; and the availability of water for additional use from the Yakima and Columbia Rivers. more >>

Partners

The State of Washington Department of Ecology is Reclamation's cost-share partner for the study. In 2003, the State of Washington appropriated $4 million to expend under contract with Reclamation. Additional appropriations have been authorized by the legislature to complete the Storage Study.
