Yakima River Basin Water Banking

Ecology is using water banking to make water available for new uses.  Mitigation being sold by the water banks offsets the impacts of new uses on the Yakima River system.  The mitigation also supports the new users’ ability to continue using water even if all water rights with priority dates after May 10, 1905 are completely shut off.

Although most of the banking activity is taking place in Upper Kittitas County due to the Groundwater Rule, new permitted uses in the Lower Yakima basin also must be mitigated.  Most of the Yakima water banks also serve the lower Yakima Basin.

Water Storage and Exchange Contract

How much of those trust water rights have been assigned to the USBR-Ecology Storage contract?

Yakima Basin Integrated Water Resource Management Plan

The Yakima Basin Integrated Water Management Plan, built on cooperation and collaboration among water users, lays the groundwork for stable water supplies decades into the future.  The alternative to moving the plan forward is contentious and costly legal battles over water that will leave many losers among water users in the basin.

  • Upper Kittitas Groundwater Study - July 17, 2014  The United States Geological Survey (USGS) released Scientific Investigations Report 2014-5119 titled Hydrogeologic Framework and Groundwater/Surface-Water Interactions of the Upper Yakima River Basin, Kittitas County, Central Washington by Andrew S. Gendaszek, D. Matthew Ely, Stephen R. Hinkle, Sue C. Kahle, and Wendy B. Welch.
  • Yakima River Basin Groundwater Study October 2011 - Final USGS report on Yakima Basin groundwater
  • Water Transfer Working Group - The Water Transfer Working Group (WTWG) is a voluntary team of agencies and water users that meet to provide technical review of proposed water right transfers in the Yakima basin.  The WTWG process guides applicants to those types of water right changes and transfers that can quickly and easily gain approval from the state.  Speed, certainty and convenience are important factors for drought year water right transfers.
  • Yakima River Basin Water Enhancement Project (YRBWEP)  Ecology, the US Bureau of Reclamation, other federal and state agencies, tribes, local governments, environmental organizations, and water users are working together to address water supply issues in the Yakima River Basin. The Office of Columbia River is initiating preparation of a programmatic Environmental Impact Statement for the Yakima River Basin Integrated Water Resource Management Plan. To meet the basin’s water needs, the Integrated Plan’s seven elements include: reservoir fish passage; structural and operational changes to existing facilities; surface water storage; groundwater storage; habitat/watershed protection and enhancement; enhanced water conservation; and encouraging water marketing.
  • Yakima River Basin Surface Water Adjudication - Draft schedule of rights, court documents list, monthly notice/court calendar Supreme Court No. 86211-7  - Supreme Court issued its decision in the Acquavella V case.- March 07, 2013
  • Manastash Project - Manastash Project, Phase I Manastash Creek is an important Yakima River tributary, which drains a 100-square mile watershed in Kittitas County lying west of Ellensburg, Washington.  Approximately 30 miles of potential high-quality salmonid habitat remains in the upper portions of the watershed, which lie primarily within the Wenatchee National Forest.
  • Bureau of Reclamation-  Yakima River Basin Water Storage Feasibility Study Upper Columbia Area Office 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.
