Lake County, South Dakota

Lake County boasts many lakes. The photograph below is of Lake Herman. Several decades ago an air pumping project was put together on Lake Herman to help it avoid the massive fish winterkill caused by cold conditions and multiple feet of ice build-up. Air is pumped into the lake during the winter months to help aerate the water and causes part of the ice covered lake to be open. Great for fish not so great for unsuspecting snowmobilers.
