Title

Lower Russian River Bank Stabilization Project

Description

The stream banks along the Russian River at the Odd Fellows Recreation Club have been substantially eroded, resulting in the loss of most of the mature bankside trees and a 2000' long and 100' wide section of bank (composed of mainly fine sand). The bank profile is now concave and has been colonized by weedy annuals that will not withstand erosion processes, particularly those associated with big flood events. The erosion is the result of in-channel flows as well as flow over the top of the bank and super-saturation of soils which occur during receding floods. The loss of mature trees has allowed accelerated erosion of the riverbank and created the concave shape (i.e., slumping debris at the toe resting at about the natural angle of repose for a fine granular material, and a steep, almost vertical bank). The California Department of Fish and Game is executing a Lake and Streambed Alteration Agreement Number 1600-2009-0101-03 pursuant to Section 1602 of the Fish and Game Code to the project applicant, Evan Engber/Bioengineering Institute.
