Winter Draw Down Damage

Sediment Ice Heave photos


DNR claims it reduces shoreline erosion yet Steve Hjort has pictures and we all saw for ourselves during the winter tour (2003) with the DNR that the frozen exposed lake bottom pushes and heaves the same as ice on the shorelines.

Actually it has a greater erosion quality than ice because ice would be at a higher elevation than frozen lakebed, a frozen lakebed pushes directly into the root systems whereas ice - if lake levels are high enough - tend to slide or push over the tops of the vegetation.
