| Description |
The Washington Department of Ecology (Ecology) is charged both with administering state water rights laws and the federal Clean Water Act Section 401 water quality certification. The Department of Fish and Wildlife (WDFW) is mandated to protect habitat, including streamflows. 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. |
