Streambank & Lakeshore Protection

Riprap is large rocks placed in areas experiencing erosion that cannot be controlled with vegetation. Here riprap is placed on a streambank to prevent further erosion and water quality degradation from sediment. Photo courtesy of Hawk Creek Watershed Partnership.

Streambank and lakeshore protection involves using vegetation or materials such as riprap or gabions to stabilize stream, river or ditch banks or lake or reservoir shores, protecting them from erosion or sloughing. It also includes removing snags or debris from banks and channels to improve stream flow and minimize bank erosion caused by high-velocity water flowing around the obstructions.
Sediment loading is a major water quality concern in Minnesota, and streambank erosion is a significant source of sediment in some Minnesota landscapes. Streambank and lakeshore protection is especially important for restoring and protecting surface water quality in these landscapes.
