Ecosystem Restoration Detailed Project Report with Integrated Environmental Assessment (PDF)
PROJECT LOCATION AND DESCRIPTION
The project is located along Dry Creek, below USACE Warm Springs Dam (WSD) and near the City of Healdsburg in Sonoma County, CA. An existing Corps project, Warm Springs Dam, was 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, mandated that the Corps perform various Reasonable and Prudent Measures to save threatened salmonid species. The project restored 6.7 acres of stream and riparian habitat along 0.5 miles of stream by improving habitat complexity and hydrologic connectivity with the floodplain through the construction of side channels, large wood structures, riffles, and alcoves pool features. Riparian habitat was improved through invasive species reduction and riparian revegetation with native species. These features have already proven successful in enhancing shelter for young salmon and steelhead as they spend a critical first year or two in freshwater before migrating to the ocean. Project construction was completed in the fall of 2018 and the project is currently in the monitoring and adaptive management phase. USACE intends to begin the process to turn the project over to the non-Federal Sponsor in Summer 2023.
