Description

Ninety percent design plans and permit package developed for stream habitat and fish passage improvement on Cochran Creek and Quail Slough.

Project Benefit

Design plans will lead to remediation of the tide gate migration hindrance at the confluence of Cochran Creek and Fay Slough which will open up 1.93 miles of accessible habitats for juvenile Coho Salmon rearing and adult Coho Salmon spawning. The new tide gate to be installed at the confluence of Quail Slough and Fay Slough will re-introduce a muted tidal cycle into Quail Slough and provide new brackish non-natal rearing habitats for Coho Salmon.

Description and scope of the plan implemented

In the tidally-influenced lower watersheds of Humboldt Bay, such as Cochran Creek, anthropogenic activities have reduced the quantity and quality of the tidal freshwater and estuarine rearing habitat available to salmonids. This planning/design project will produce fully-permitted, final design plans, that once implemented, will establish access for all life phases of coho salmon to utilize suitable rearing and spawning habitats in Cochran Creek and its tributary Quail Slough.
