Merced River Salmon Habitat Enhancement Project - Ratzlaff Reach
Phase II (Ratzlaff Reach) of the Merced River Salmon Habitat Enhancement Project (MRSHEP), but the first construction is located on the Merced River between river miles 40.0 and 40.5, approximately 6 miles southwest of the town of Snelling.
To create 300 foot wide floodway with a berm to isolate the river from the pond. Failure of berms in the Ratzlaff Reach had allowed the river to flow through an abandoned gravel pit. The river abandoned a channel that was already heavily constricted and overgrown with vegetation. The berms had limited the river width to fifty feet in some areas before it failed. Of the original 46 acres of the project pond (including the small channel remnant), the floodway and berm eliminated about 20 acres and isolated an area of about 26 acres.
