We swam in this lake. It was early September and the water was like liquid ice. Like a fool I ran in, yelling and laughing, tripped on the rocks, fell face down in 3 feet of water and would of wailed like a dramatic baby except that all the breath was knocked out of me by my body compressing itself inward from the shock of the cold water. The water was fresh and clear, unlike Lake Michigan riddled with algae slime and mussels. We got used to the water, well, kind of, and even tricked a tourist into coming in for a swim.
