This project includes the planning and design of a fish ladder under Highway 15 along Trabuco Creek. A physical model was designed and built at the request of U.S.FWS and NOAA Fisheries, at both 20:1 and 6:1 scale. A complete sediment transport analysis was also conducted. The next step is beginning the permitting process.
Removal of the existing fish barrier will open up access to 15 miles of steelhead spawning and rearing habitat. The project also included riparian habitat enhancement adjacent to the fish barrier to benefit other species. The Department of Fish and Wildlife has identified removal of the fish passage barriers as a high priority, and along with the Wildlife Conservation Board approved funding to help remove the barrier.
