Project: Mill-Shackleford Creek Fish Passage Restoration Project

Description: The partial barrier blocks access for juvenile coho salmon to over one mile of critical rearing habitat during summer months. The low water crossing and unimproved ford also negatively impact water quality and floodplain function. Funding will be used to remove a partial barrier for juvenile coho salmon caused by a seasonal low water crossing structure and to replace the unimproved ford and low water crossing structure with a 66-foot prefabricated, free span, weathered steel, heavy-load, vehicle bridge. Removal of the ford crossing and associated approach roads within the floodplain of Mill Creek is expected to significantly improve channel-floodplain interactions at a critical point where the dynamics of the channel transition from a more confined valley to a broader and more complex floodplain.

Reference Number: 3600BP1896020

Implemented By: California Trout Inc.

Objective: Specific objectives of this Project are to: 1) Completely remove a partial barrier limiting access for juvenile coho to 1.5 miles of critical rearing habitat in Mill-Shackleford Creek; 2) Provide unimpeded passage for Coho salmon at all life stages at all flows; 3) Decommission an existing, heavily used, low water crossing structure and unimproved ford and approximately 1,050 linear feet of exiting timber road that currently maintains hydrologic connectivity with the stream; 4) Construct one 66-foot prefabricated heavy vehicle bridge and demolish one existing light load (railcar) bridge and 5) Restore approximately 0.3 acres of riparian area
