San Luis obispo creek city culvert fish passage enhancement project

San Luis Obispo Creek runs through a tunnel under downtown San Luis Obispo, and inside there are several partial barriers over which adult and juvenile steelhead trout have difficulty migrating. CCSE has completed a feasibility study of modifying the barriers inside the tunnel to improve fish passage and is currently weighing possible alternatives with partner organizations such as the City of San Luis Obispo.

Alternatives evaluated include:

1) Constructing a high-flow by-pass;

2) Constructing a step-pool channel;

3) Constructing a low-flow channel; 

4) Doing nothing.
