This is what was sent to me....
Natural Springs is very diver friendly. There are 3 boats, 4 cars, 3 platforms, 2 swim through tubes and a deep (30ft) trench around most of the wall. Definitely cold on the bottom. The best part of diving there, is all the life in the water. Very large bass and walleye. also their are several rock ledges full of juvinals. the bottom in the shallow part is usually grass covered. We have put guide lines in to help with navigation and it is easy to find your way around. First thing you see is yourself in the Big screen TV. and then a computer and finally the beach with umbrellas and chairs. Hope this is some help
Jen, the info above is quite accurate. The trench goes to 31 feet max. Most dive time will be spent at 16 to 18 feet. Me, I liked the guidelines as well.
