DNR Activating Winter Aeration Systems
Posted: 12/21/2012
Winter Aeration systems have been started at the following lakes: Five Island Lake (Palo Alto County); Ingham Lake (Emmet County); Center Lake (Dickinson County); Silver Lake (Dickinson County); Clear Lake (Cerro Gordo County); Crystal Lake (Hancock County); and Rice Lake (Winnebago County).

Use extreme caution on lakes with aeration systems. These systems create open water to reduce the likelihood of a fish kill during harsh winter conditions, but it so creates an area of thin ice surrounding the aerator that should be avoided.
