Zmrhal/Rauth Coweeman Restoration

The project is upstream of a geologic pinch point that forms a mid channel bar with several side channel areas. The Coweeman River has eroded the existing narrow forested buffer exposing alluvial soils in agriculture land use and has about abandoned the side channel habitat. A project conducted during 2006 slowed streambank erosion downstream and continued abandonment of the side channel habitat. This project will complete restoration work upstream of the 2006 project site and improve channel stability and habitat diversity by: 1) restoring connectivity to 1000 feet of side channel habitat, 2) increasing channel stability and stream bank stability over 400 feet of the Coweeman River, and 3) increasing in stream and side channel habitat through the placement of large woody debris.
