    Corps will pay 75% of costs for habitat enhancement work in 2018

    (Santa Rosa, CA) - The U.S. Army Corps of Engineers (Corps) and the Sonoma County Water Agency (Water Agency) signed an agreement this week on a cost-sharing agreement for construction of a $6.3 million portion of the Dry Creek Habitat Enhancement Project. Under the terms of the agreement the Corps will pay for 75% of the costs ($4.76 million) and the Water Agency will pay 25% of the costs ($1.59 million) for the habitat work to be constructed in 2018.

    To date, nearly two miles of habitat enhancement work has been completed, with another half mile of work under contract for construction in 2017. The agreement with the Corps will add an additional third of a mile of construction in 2018. The Russian River Biological Opinion requires habitat enhancement of six miles of Dry Creek to improve summer rearing conditions for endangered coho salmon and threatened steelhead while allowing the Water Agency to maintain existing flows in Dry Creek for water supply purposes.

    “We are very pleased with this cost-sharing agreement and we look forward to continuing our productive and cooperative partnership with the Army Corps of Engineers,” said Water Agency Chairwoman Shirlee Zane.  “Our board fully supports the effort to protect the threatened and endangered species and preserve and enhance our Russian River watershed.”

    Habitat work will be funded by the Corps under its Continuing Authorities Program Section 1135. The 2018 habitat construction is scheduled to take place about a mile upstream of the Westside Road Bridge.

    “We are proud to be part of this regional and interagency effort with a focus on bringing threatened and endangered fish back into the Russian River Watershed,” said Lt. Col. John Morrow, San Francisco District commander. “Signing this Project Partnership Agreement brings us one step closer toward achieving the goals of the Russian River Biological Opinion.”

    The habitat enhancement project is part of the Russian River Biological Opinion that requires the Water Agency to enhance six miles of the 14-mile length of Dry Creek in order to slow the high water velocity in the creek, which was found to be detrimental to the survival of young Coho salmon and steelhead. Project elements include bank stabilization to reduce erosion, anchored log jams to provide refuge and slow the water, and constructed backwaters and side channels to give young fish places to escape summer and winter high flows, and native plants to reduce erosion and create shade.
