Estuary Management Project - EIR

A plan to change the way the Sonoma County Water Agency (Water Agency) manages the Russian River estuary from May 15 through October 15 is the subject of the Russian River Estuary Management Project Final Environmental Impact Report.

The proposed changes in estuary management are required by National Marine Fisheries Service Russian River Biological Opinion. The purpose of the project -- which includes a new way of opening the sandbar that sometimes closes the mouth of the Russian River, where it flows into the Pacific Ocean near Jenner – is to create a more productive environment for young steelhead.

Since the mid-1990s, the Water Agency has artificially breached the sandbar when it closes and water levels in the estuary threaten low-lying properties. When the sandbar is breached, salt water from the ocean mingles with river water, creating saline conditions. In the Biological Opinion, National Marine Fisheries Service (NMFS) biologists found that the fresh water lagoon that is created when the sandbar closes naturally would help threatened steelhead during summer months. In order to reduce the risk of flooding while maintaining this fresh water lagoon, the Water Agency worked with consultants to create a plan for sculpting the sandbar that will allow river water to flow over the top but keep ocean water from entering.
