Old bridge removed to create salmon habitat

Obstacle has prevented fish from migrating up Secret Ravine Creek

The City of Roseville is removing a long-standing physical barrier in Secret Ravine Creek that will open up 10 more miles of salmon habitat.

The project involves removing an abandoned 1930s bridge and utility crossing on the creek corridor located near Eureka and Taylor roads that prevent salmon from migrating upstream to spawn.

Workers will also modify the creek bed to improve fish passage under all flow conditions, widen the channel and plant native flora.

Secret Ravine is a perennial stream that supports spawning, juvenile rearing and emigration of fall run Chinook salmon and steelhead. The creek is part of the Dry Creek Watershed and the Dry Creek Conservancy District is assisting on the project.

Construction work will end Oct. 15 and subsequent restoration efforts are expected to last through the month. Salmon runs begin in October, when salmon swim back up the river where they were born to spawn. Salmon die after laying their eggs.

Delyn Ellison-Lloyd, senior engineer for the city, said it will take some time before salmon return to the area of Secret Ravine Creek that has been blocked.

The project will cost about $400,000 and is paid for by a Proposition 84 grant from the Department of Water Resources. This grant program provides funding to public agencies for projects that assist in meeting long-term water needs, such as the delivery of safe drinking water and the protection of water quality and the environment.
