Willamette Basin Flood Control Project

Willamette River Basin; Willamette River, Lane, Linn & Marion Counties, Oregon

Project Profile

The Willamette Basin Flood Control Project blocks access to historical habitat and degrades downstream habitat for ESA-listed fish. NOAA Fisheries' 2008 biological opinion covers a 15-year period and requires the three action agencies to carry out a variety of measures to reduce project effects on listed fish. Plans include upstream and downstream fish passage, improved minimum and maximum downstream flows, reduced ramping, habitat restoration, and extensive research and monitoring.
