COYOTE VALLEY DAM, Hanson-Windsor Ponds 

CONTINUING AUTHORITY, SEC. 1135

 

PROJECT LOCATION AND DESCRIPTION

This project study area is located on the east fork of the Russian River near the city of Ukiah, California. The Russian River drains an area of 1,485 square miles; approximately two-thirds of the drainage area is in Sonoma County, and the remainder is in Mendocino County. The existing Corps project, Coyote Valley Dam (also known as Lake Mendocino Dam), which was completed in 1957, consists of a 160-feet-high earth-filled dam and a reservoir with a storage capacity of 122,400 acre-feet. The authorized project includes sediment, flood control, and domestic and agricultural water supply pools with a total storage capacity of 199,000 acre-feet. Because local interests considered it unnecessary at the time, an additional water-supply portion of the authorized project (77,000 acre-feet) was deferred following Congressional authorization of the project in 1950.  As a result of the 2008 National Marine Fisheries Service’s (NMFS) Biological Opinion (BO) concluded that the existing Coyote Valley Dam is likely to jeopardize the survival and recovery of the Endangered Species Act (ESA) listed Central California Coast (CCC) steelhead and California Coastal (CC), the Endangered Habitats Conservancy (EHC), supports a project to provide improvements to the ESA listed species habitat as well as floodplain and riparian habitat that is critically limited in the Russian River watershed below the dam.  Together with the EHC, the US Army Corps of Engineers (USACE), San Francisco District (SPN) has determined that these is strong potential for implementation of a policy compliant restoration project in accordance with Section 1135 of the Continuing Authorities Program (CAP) to restore 356-acre of a former floodplain gravel quarry along the banks of the Russian River immediately west of the City of Windsor, Sonoma County, California.
