Warm water plus cold air created cool fog. I believe one of my local lakes is beginning to turnover. It was crystal clear last weekend, but now it's becoming a bit cloudy but no smell. The water temperature still seems somewhat warm, in the low to mid-50s at the surface. Fishing was challenging for me today; I only managed to catch one. It is hard for me to tell when my lake has started the turnover. Does anyone else know for sure when their lake has?
