DRY CREEK (WARM SPRINGS) RESTORATION, SEC. 1135
Ecosystem Restoration Detailed Project Report with Integrated Environmental Assessment (PDF)
PROJECT LOCATION AND DESCRIPTION
The study area is located in northern California along the Russian River at Lake Sonoma and Warm Springs Dam, near the cities of Geyserville and Cloverdale, about 75 miles northeast of San Francisco, California. The Russian River drains an area of 1,485 square miles. Approximately two-thirds of this area is in Sonoma County, with the remainder in Mendocino County. The existing Corps project, Warm Springs Dam, is an earthen dam 319 ft high and 3,000 ft long, completed in 1983. After the Dam was built there was an increasing awareness of adverse impacts to the anadromous fish populations. A Biological Opinion (BO), issued by the National Marine Fisheries Service on Dry Creek at Warm Springs Dam, mandates that the Corps perform various Reasonable and Prudent Measures to save threatened salmonid species. This CAP Section 1135 study will look at restoration options consistent with the BO findings and will investigate stabilizing eroding stream banks, restoring riparian habit, enhancing pools’ shade, and enhancing shelter for young salmon and steelhead as they spend a critical first year or two in freshwater before migrating to the ocean.
