Mill Creek Notch Ward Dam Fish Ladder to Improve Passage

The irrigation dam and fish ladder are owned and operated by the Los Molinos Mutual Water Company (LMMWC) in Los Molinos, California. For this project, the first step will be construction of coffer dams, then the concrete weirs will be notched at their apex, the concrete will be rounded, finished and sealed, stainless steel channel brackets will be bolted on and flashboards will be installed. During high flows, the flashboards will be removed so the fish ladder will pass sediment and gravel downstream. The flashboard in/out option will also enable more efficient clean out of any sediment trapped in the fish ladder pools. The work is expected to be completed during low flows in the summer/fall of 2018. Due to environmental conditions, the work period may possibly extend into the summer/fall of 2019. This award is made under the authority of the Central Valley Project Improvement Act, Title 34, Public Law 102-575.
