Restoration of streams is a common activity in the Corps’ ecosystem restoration projects. Typical objectives relate to fish habitat, water quality, and floodflow attenuation. Techniques for stream restoration and management are described in tech notes such as:
Bioengineering techniques for streambank stabilization have been developed and applied in many situations, and can significantly improve a stream’s condition. Benefits accrue to fish and wildlife habitat, water quality, floodflow attenuation, aesthetics, and sometimes cultural resources.
