Merced River and Floodplain Restoration
California's Merced River, below the Crocker Huffman Dam, was once a wandering gravel-bedded river with a large and frequently inundated floodplain supporting a variety of flora and fauna. Impacts such as dam construction, flow regulation, diversions, and gravel mining have impaired the river's ability to support viable populations of anadromous fish.
ESA is part of a team leading channel and floodplain restoration for over two miles of the river. We are providing full design services for channel and floodplain grading, hydraulic modeling, cost estimating, and preparation of restoration plans and specifications. Implementing an innovative approach for fisheries restoration, our team has used available funding and existing site constraints to maximize the physical habitat while ensuring that designs are geomorphically stable and fit within overall site energetics. Key to the project's success is creating floodplain rearing habitat for juvenile salmonids while ensuring achievable spawning depths and velocities.
