Yeah dove otter lake a few weeks back. There is some info avail. A small boat sunk not too far out. Viz not great, but doable. Very cold at thermo. Can jump off dock or shore entry near boat ramp. Overall though I had a good time diving there... Just got to be prepared for the cold!
Other than that there is Lake Fenton... believe entry near the community center.
Both locations require a diver flag on surface.
Going out to Spring Mill pond tomrrow night with the some members of the Great Lakes Wrecking Crew (scuba board). From what I understand it is not very deep, but a good spot during the week to dive. Will have more info once I get there and dive it.
Otherwise any state park / lake area allows diving. Genesee county is not very friendly for divers and besides Lake Fenton there is not much else avail. here... butI am checking on some more sites within an hour of here to do some fairly local diving.
Did get offered someone pond not to dive in not too far from home but since it has not been dove before uncertian of the conditions there. Know it is not real deep as it is man made and on a private property... Other than that heard a rumor of a possible site in Millington.. Another Fairly large pond about the size of Gilboa Quarry.. My LDS is doing some checking on that for possibility of future dives for us locals.
Yeah sould love to dive with ya! Lemme know what else you may have found out.
