Moving
Ahead with Migration Barrier Removal. Since 2001, Mendocino
County has completed 10 projects. The County has slated 1 project for
construction in 2010: Ryan Creek, with potential for the 5C Program to complete
a Caltrans & private driveway crossing upstream on the South Fork of Ryan
Creek during the same year. Caltrans plans to complete the North Fork Ryan
Creek barrier removal project within the next 3 years. All County projects
have restored access to ~ 17 miles of spawning and rearing habitat for coho
salmon & steelhead.

Completed in 2001, the Migration Barrier
Modification Project on Bear Creek restored access to steelhead trout habitat
on Bear Creek above Branscomb Road. Steel baffles were installed and cemented
into the culvert bottom. This project was completed in conjunction with 2
other barrier modifications on Branscomb Road at Windem Creek and Taylor Creek.
