  • Thousands of redwood logs and root wads are needed to create habitat for the demonstration project. Loggers from Sonoma and Mendocino counties are delivering these logs and root wads to a staging site near Warms Spring Dam.
  • Construction of the Water Agency’s first phase of the demonstration project was completed at Quivira Vineyards and Winery property in November.
  • Construction of the Corps project (below Warm Springs Dam) began in September. The company that is designing the project will also be doing the construction.

Background

The Russian River Biological Opinion (issued in 2008 by National Marine Fisheries Service) requires the Sonoma County Water Agency (Water Agency) and the U.S. Army Corps of Engineers (USACE) to provide hiding places and refuge in Dry Creek for young coho salmon and steelhead trout. While the cold, clean water in Dry Creek is ideal for salmon and steelhead, the water moves too fast for young fish to thrive. The Biological Opinion requires that six miles of habitat be constructed in the 14-mile long creek. The first mile of enhancements, which includes logs, boulder and thousands of native plants, must be complete by 2014.

The Water Agency is working with a willing group of Dry Creek landowners on a one-mile habitat enhancement demonstration project. The purpose of the project is to demonstrate to regulators, landowners, and local decision makers the feasibility of Dry Creek habitat enhancements on a smaller scale and, in particular, to determine how they could be constructed, what they may ultimately look like, and how effective they are before implementing the full six miles of habitat enhancements on Dry Creek. The project is centered on Lambert Bridge, near the middle of Dry Creek.

On November 15, 2011, the Water Agency Board of Directors approved the demonstration project and the environmental document (described below) analyzing the project.

Initial Study and Mitigated Negative Declaration for the Habitat Enhancement Demonstration Project

The Sonoma County Water Agency (Water Agency) is the Lead Agency under the California Environmental Quality Act (CEQA) for the proposed Dry Creek Habitat Enhancement Demonstration Project (Dry Creek Demonstration Project). The Water Agency prepared an Initial Study and Mitigated Negative Declaration (Initial Study) for the project in accordance with CEQA. The Water Agency’s Board of Directors approved the Initial Study on November 15, 2011.
