Merced River - Hatchery Project
The Merced Hatchery Project is on the Merced River near Snelling, just below the Crocker-Huffman dam. Originally constructed in 1991, the project consisted of excavation and replacement of bed material in approximately 400 feet of channel to improve salmon spawning conditions. The project has since evolved into a gravel replenishment site, with about 200 feet of the channel being periodically filled with suitable spawning material.
Excavation and replacement of bed material in approximately 400 feet of channel to improve salmon spawning conditions. Permanent cross-sections have been set up at the project site to enable monitoring of the status of the placed gravel. When large flows occur, some of the gravel may travel downstream. When the surveys at the monitoring sections show a significant enough drop in bed elevation, gravel replenishment is scheduled.
