Short Description

The Washington Department of Fish and Wildlife (WDFW) recommends instream flows to be conditions of water rights or Clean Water Act Section 401 certification (issued by Ecology) and hydroelectric power project licenses or exemptions (issued by the Federal Energy Regulatory Commission FERC). When a major water project is planned, WDFW and Ecology request that the project proponent conduct an instream flow study in consultation with the agencies to provide adequate information on which to base an instream flow recommendation or requirement. This document provides information on instream flow study guidelines.
