CommentsWe have a cottage on the lake since 1964 and have been seeing the fresh water jelly fish off and on for about 10 years. I did not think to take a picture or catch any this past weekend but will try to catch some next weekend if they are still floating around. They stay 1-2 feet below the surface and this past weekend we saw thousands of them from one end of the lake to the other end
