Grindstone Lake

[DanL]

Lonnie - In my opinion, not worth it.  Dove it two years ago - No access allowed from the south end, very bad access from the public launch - very shallow for a long way, boats, a VERY tannic stream entry.  We tried a house to ask for access and were turned back by some very un-nice dogs.
Finally got reasonable access from the west bank, but the bottom undulates - you go to 15 ft and over a bank up to 10ft, then to maybe 20 ft then back up to 8ft.  It's like a roller coaster. Look at the map - some deep holes w/steep sides, but a whole lot of washboard up-and -down bottom profile.
Also look at the DNR viz: 7.8ft!  The water was like diving in dark tea.  Light doesn't penetrate it either.  We tried diving for about 45min and gave up.  Went to Tobey's and consoled ourselves with the great cinnamon rolls and coffee.
If there are horse bones in there, you would never see em - everything must be stained a uniform brown in brown water.
