West Fork Walker River, Yerington, NV
This project was initiated by local landowners in cooperation with USFWS to address habitat concerns along the Walker River. The exceptional trout fishery through the upstream canyon deteriorates rapidly as the river enters the agricultural valley south of Yerington, NV. Most of the decline in habitat is due to past management and channel alterations that leave the West Fork of the Walker River over-widened, shallow, warm, and susceptible to lateral erosion.
Landowners on the Cottonwood Ranch recognized these issues and worked with USFWS to address the resource problems. StreamWise was asked to suggest methods to improve habitat features and reduce the lateral instability through the property. The following are photographs that depict rock structures used to deflect flows away from eroding banks, narrow the river width to improve velocity, create habitat scour holes below the rocks, and enhance trout fishing opportunities.
West Fork Walker River Irrigation Take-Out Project
This project was constructed just upstream of the Cottonwood Ranch at the mouth of the canyon and was designed to facilitate irrigation diversion without impeding fish passage. The W-Weir rock structure diversion is based on specifications by Dave Rosgen, of Wildland Hydrology. The rock placement has several advantages over the traditional concrete check dam.
The following photos depict the project features.
