I just completed my OW dives here. The water is warm for a northern lake (68 degrees in November). Visibility was poor (3-8 ft). Lots of curious catfish. A couple of training platforms are located at 25 feet, one marked by a buoy. Deeper ones exist but I don't know where they are. Site gets to around 130 feet. Didn't venture nearly that far down. Ominous power plant across the lake. Not your Florida Keys diving, but a good place to do some training dives, refresh your skills, or try out equipment in the winter without venturing to the tropics!
