Features of the Dive Site

Second Divot, named because it looks like a slight cut out of the shoreline, and the second one, as traveling from the south. Relatively clear in high water. The rocky slope on the west side make this dive site easy to navigate north or south along the shoreline.


Small mouth bass and walleye may be seen in the deeper areas. Look for underwater trees which may shelter juvenile species. Long line trolling fishing gear is likely to be found here, usually wrapped up in trees. TRUST YOUR COMPASS when navigating after stopping at a bush or tree, as the similar looking areas can make you feel you are going south when you are going north.

Diver Cautions

Boat: Be sure to bring a HIGHLY VISIBLE YELLOW OR ORANGE dive buoy with tethered diver down flag. The red dive buoys are not visible to other boats against the red rock reflections on this side of the lake. Boaters are curious, and may not respect the 100 foot rule because they cannot see your flag at the speeds they are traveling. Wind and storms can come up quickly in the afternoons. Be prepared with more than one anchor (forked hook preferred) to be the most prepared. Be sure to anchor your boat properly, and keep a boat captain or first mate to watch topside in order of prevent drift out of the no wake zone. The bottom is full of loose light rocks, which will not hold your boat in the wind. Waves are also strong due to the traffic outside of the no wake zone.

Water: Long line fishing will be found here, usually with connected bottom-bouncers and walleye rigs. Bring a cutting tool and remain calm if you are caught. Also, fishing gear that you pick up may hooks still attached, which can puncture fingers, dry suits and dry gloves. High traffic area outside no wake zone, WATCH YOUR ASCENT and only ascend under a buoy.

What to Bring

Park pass, buoy, line, reel. Cutting tool. Anchor (two recommended). Life jackets for all on board. Topside spotter/someone who is able to move your boat in case of drift, Diver Down flag and an Alpha flag for your vessel. See general regulations for more information. If you like collecting fishing gear, bring a lure bottle and cutting tool.
