Runoff and sedimentation

In the Lake Superior basin, water runs off the clay soils very quickly, especially during flashy rain events and fast snow melts. The rapid runoff changes the shape and character of streams by causing erosion of soils and streambanks and leads to heavy sedimentation.

Sediment is one of the biggest challenges in our watersheds. Too much suspended sediment in a stream can impair fish breathing and vision. Sediment on the streambed reduces habitat space for macro-invertebrates and can cover fish eggs. Sediment can also pile up along the river’s channel, leading to changes in hydrology, and can cause the Chequamegon Bay to turn red.
