Butte Creek/Sutter Bypass Weir 1 Improvement Design and Permitting Project

The Butte Creek/Sutter Bypass Weir 1 Improvement Design and Permitting Project aims to improve the passage of anadromous fish species, specifically spring-run Chinook salmon, by partially removing the existing weir and constructing a rock ramp. The project is located in the Sutter Bypass, California, and is funded by the Fish and Wildlife Service. The project involves designing and permitting the removal of the weir and construction of a rock ramp to maintain water surface elevations and provide reliable water diversion rates and flows for fish passage. The project also includes a feasibility study and report, as well as a technical advisory committee to oversee the project. • The project will improve adult and juvenile passage of anadromous fish species, specifically spring-run Chinook salmon. • The project will minimize negative side effects, such as flood risk, channel stability, and upstream habitat conditions. • The project will provide a feasible and cost-effective solution for improving fish passage. • The project will require maintenance and monitoring to ensure the long-term success of the project. • The project will be funded by the Fish and Wildlife Service, with an estimated funding amount of $850,000.
