Bank Stabilization

an example

This project was completed by Adopt-a-Stream in 2003 on Little Bear Creek.  The project's objectives were primarily to reduce sediment load into the stream by stabilizing the banks.  The short term solution was placement of in-stream large woody debris.  V-weirs were also placed to direct stream flow away from the banks. The long term solution included planting the five hundred feet of riparian with native vegetation.  In the short term, the woody debris will prevent erosion by redirecting and slowing flows in the peak seasons.  This woody debris will also provide habitat for aquatic life.  In the long term, the vegetation will provide a source of continual wood for the stream and stabilize the stream banks by binding soil in the root systems. 

In-channel LWD protects banks from erosion and provides fish habitat.
