Comments"My limnology class and I have seen these in the lake every fall at least for the past decade. I could look up the first sighting date if it is important. This year they are especially common, with some nice ones at volleyball size. The lake has no boat access but flyfishers bring float tubes to the lake. Many dog walkers use the trail around it."
