Columbia River reports & documents

Here you will find all our associated documents for the Office of Columbia River. We work diligently to document and report the work we do to develop water supplies that provide both instream and out-of-stream benefits as mandated by the Legislature.

Water supply forecasts, integrated management plans, and an atlas on fish streamflow needs are among the reports prepared by the Office of Columbia River.

Water supply and demand analysis, environmental reviews, focus sheets

In support of our work to find water solutions in the Columbia River Basin, we undertake scientific studies, and prepare project reports and analysis. These reports include project environmental reviews, feasibility studies, economic analysis, focus sheets, legislative updates, and at-a-glance products.
