My shoreline is eroding. Should I install a seawall?
Erosion is a potentially serious problem to lake shorelines and occurs as a result of wind, wave or ice action, or from overland rainwater runoff. While some erosion to shorelines is natural, human alteration of the environment can accelerate and exacerbate the problem. Erosion not only results in loss of shoreline, but negatively influences the lake’s overall water quality by contributing nutrients, sediment and pollutants into the water.

Seawalls are generally only recommended along very steep shorelines or those repeatedly battered by wave action and only when no other options are feasible. Seawalls provide neither positive aesthetics nor fish and wildlife habitat. Additionally, they generally reflect waves away from the shoreline and back into the lake. While this prevents shoreline erosion, it can actually create turbid conditions in the shallow water along the shoreline as the reflected waves re-suspend sediment into the water column. A more environmentally friendly alternative to a seawall is a buffer strip, which will hold soil along the shoreline effectively and may help filter upland nutrients and pollutants.
