Chinook salmon have lost more than 90 percent of their
historical range in California due to the construction of dams
and other fish barriers. Migrating Chinook salmon have been well
documented in Marsh Creek and FOMCW has led salmon monitoring
tours for the public every fall for the last several years. The
salmon's journey up Marsh Creek is cut short however, because a
6-foot tall concrete structure located approximately four and a
half miles from the creek's mouth prevents salmon from reaching
several miles of suitable spawning habitat in lower Marsh Creek
and its tributaries. Known as the "drop structure," it is a
physical barrier to migrating fish, even when the creek has
plenty of water. This project will build a ladder over the drop
structure so fish can access an additional seven miles of Marsh
and Sand Creeks. If the ladder is built, Chinook salmon will be
able to swim right through the City of Brentwood. The project
will also indirectly benefit other species by raising awareness
of Marsh Creek. All a
