The stream flow restoration priority maps show flow restoration needs and priorities for 18 basins in Oregon. They were developed by the Oregon Department of Fish and Wildlife and the Water Resources Department, in fulfillment of Oregon Plan Measure IV.A.8, Identify Instream Flow Priorities. Stream flow restoration priorities have been identified for four seasons: Summer (July - September), Fall (October - November), Winter (December - March) and Spring (April - June).Priorities have been developed based on the Water Resources Department nested watershed structure, called Water Availability Basins (WAB). The maps display each river basin, with rankings for stream flow restoration need, stream flow restoration optimism, and the State's priorities for its restoration activities. Also included are maps showing streams and rivers in the basin, and maps showing Water Availability Basins (WAB).
