2007 Columbia River Legislative Report - Columbia River Basin Water Supply Inventory

Columbia River Legislative Report

In 2006, the Legislature enacted the Columbia River Basin Water Management Program (Program), codified in RCW 90.90. The program directs Ecology to “aggressively pursue the development of water supplies to benefit both instream and out-of-stream uses” (RCW 90.90.005). The foundation of this water supply development is an inventory of storage and conservation projects that Ecology must develop, update and report to the Legislature each year.

2007 Report

The 2007 Report builds on the work done in completing the first report by increasing the number of identified projects by ten percent, determining which projects are best suited to meet instream needs and which ones are best suited for out-of-stream needs and providing a “sneak peek” at the efforts Ecology is undertaking to update the water supply and demand forecast due in 2011.

2006 Report

On November 15, 2006, approximately 4 months after the effective date of the Legislation, Ecology produced the first Columbia River Water Supply Inventory. To create the report, Ecology reviewed every published account of storage and conservation opportunities, contracted with the Conservation Commission and local conservation districts to provide data on other conservation opportunities recorded in their own internal databases or farm surveys; and employed a series of workshops, web outreach, and letters to stakeholders to solicit project recommendations.
