Lacamas Fish Barrier

Project Description

This “fish barrier” project required tight coordination with various agencies, ensuring the protection of existing fish in the associated creek. First, a temporary fish bypass system was constructed along with extensive site work; the roadway was detoured over a new temporary road surface; the old culverts were removed, and a new large precast concrete structure was built; the channel was restored according to fish passage requirements; the roadway restored to the new configuration along with side roadway barriers.
