Recent Rain Tests Hallwood Restoration Project

The storm that swept through Nevada County between the 23rd and 25th of October dropped between seven and twelve inches of much needed precipitation. This rainfall has led to, among other things, increased flows in the Yuba River. 

We sat down with one of our SYRCL scientists to learn more about how this rain event interacted with the Hallwood Side Channel and Floodplain Restoration Project, a restoration effort that SYRCL has been working on and committed to for the past five years.

Hammon Bar: A Restoration Success Story

Seven years ago, SYRCL began the first project in the Lower Yuba River to restore salmon habitat.

In 2011 and 2012 SYRCL planted nearly 6,500 willow and cottonwood cuttings across 5 acres to improve the floodplain habitat that fish use during high flow periods as refuge from swift moving water in the main river channel. 

One goal of this project was to increase riparian vegetation which would provide improved fish habitat through the increase in shading, cover, food availability, and creating geomorphic and hydraulic complexity on the floodplain.
