Nick,
We haven't gotten back up there this fall, might have something to do with the $3+ a gallon gas that we recently found ourselves with? I'll let you know if we do plan another run up there.
HAve you been hassled by the local lake patrol for freediving without a boat? I don't exactly remember getting a welcome mat for those guys last time I was out there. If you can get away with shore diving that's great, but I know they can get pretty picky aobut things like flags- which is almost a $200 fine from what some friends told me after "personal experience".
What kind of depth are you finding if you stay within 150' of shore? I know the lake drops quick, but not that quick.
That IS the Beaver lake I was talking about. You need to swim past that entry point through a shallow bay (less than 3' deep) and then over a shallow sand bar to get to the good part of the lake. Working your way around the right side basin you'll find plenty of fish to spear.
Here are a couple of shots form tha lake.
