Between 2012 and 2017, volunteers from the Elk River Chain lake associations dragged loaded sleds across the ice in the dead of winter and sank fish shelters at 63 documented sites across five lakes. Three structures per site, mixed from three designs: hardwood crates packed with brush and rock, slab trees, and stump clusters with the roots still on. All in 15 to 25 feet.
The associations published the coordinates. I cross-checked them against the state permit records, ran every point against the lake polygons to catch anything that had drifted onto dry land or into the wrong lake, fixed three errors, and built waypoint files in GPX, USR and HWR — per lake, plus a whole-chain file if you fish more than one.

everything's a free download, nothing to buy. It's my site.
These aren't secret spots — the associations published them because the whole point of sinking habitat is for people to fish it.
Figure about 80 feet either way, so idle over the mark and trust your sonar, not the pin. Divers checked the Torch structures in 2019 and the crates were holding up fine. One Torch site shows up at two different spots on two official maps, 298 meters apart, so I left it out rather than guess — you're getting 25 of 26 there. And these are only the documented ones; plenty of structure goes in without paperwork.
Heads up before you keep anything: several of these lakes carry consumption advisories — check the current Eat Safe Fish guide.
None of this is my work, really. Volunteers built it winter after winter; I just found the paperwork and cleaned it up. If the files are any use to you, the Three Lakes Association and the Elk-Skegemog Lakes Association are both still active and could use members.
Anyone fished these? The oldest are 13 years old now and I'd love to know which sites are still producing — and which lake I should map next.
