Project: Cochran Creek (Humboldt Bay) Fish Passage and Habitat Rehabilitation Implementation Project

Description: Cochran Creek’s connection to Humboldt Bay has been degraded by anthropogenic activities over the past 165 years, reducing the quantity and quality of tidal freshwater and estuarine salmonid rearing habitat. Funding for this Project will be used to improve fish passage to sustain populations of coho, steelhead, and cutthroat trout, as well as to enhance and expand tidal, brackish, freshwater and riparian habitats on Cochran Creek and Quail Slough. The project contributes to the following Proposition 1 priorities 1) Protect and restore coastal wetland ecosystems; and 2) Protect and restore anadromous and other non-game native fish habitat.

Reference Number: 3600BQ2096015

Implemented By: California Trout

Objective: The project will: * Improve fish passage and water quality (salinity, temperature) by replacing the existing tide gate with a fish-friendly side-hinged gate, and constructing a new channel to increase fish passage, benefiting anandromous fish including Coho and Chinook salmon. * Restore instream and floodplain habitat * Enhance drainage to reduce fish stranding and improve agricultural landscape function.
