Dry Creek Habitat Enhancement Feasibility & Alternatives Analysis, & Detailed Design
Dry Creek has been managed intensively for forestry, agriculture and gravel mining since the 1850s, resulting in 25 feet of channel incision. Since the mid-1980s, Dry Creek has also been highly regulated for flood control and water supply. The terms of the effective biological opinion for flood control and water supply operations in the Russian River system include substantial habitat enhancement in Dry Creek, with a target for enhancement of 6 miles of habitat in a 14-mile study reach. The habitat enhancement is focused towards ESA-listed coho salmon and steelhead trout. Since 2007, our work has included:
- Feasibility and alternatives analysis study along a 14-mile reach.
- Survey, habitat unit inventory, hydrologic analysis and hydraulic modeling, feasibility and alternatives analysis, project identification and prioritization.
- Designed and constructed the Dry Creek Demonstration Project, which included habitat enhancements over a 1.1-mile reach (constructed 2012-2014).
- Initiated design of an additional mile of projects which began construction in 2016 and are expected to be completed in 2018.
- Begun design of a third mile of enhancement work be constructed starting in 2018.
- Development of illustrative handbooks used to communicate designs with the community.
- Extensive collaboration with stakeholders, resource agencies, and community and the US Army Corps of Engineers.
