Hey Kevin, long time no see. When is your next trip to Rock? I will be down there on March 11-13 watching OW dives with the shop, but I can dive Friday on my own. My daughter is getting certified that weekend. I'm slinging doubles now....
I have dove;
Chatfield; King Fisher pond, 3' vis, 64* in early summer. Chatfield Res; about same vis & temp by dam.
Carter; dove it several times. Vis is anywhere from 15' to 1'.
Jefferson Res (10000' elevation); AWESOME DIVE. Vis down to 30 or so was about 25' or in that area, vis at 97' was about 12' or so, depends on the light. I use a 50w Hallogen can light (home made).
Glendo Res, Wyoming;
two spots. Bay areas, typically about 15' vis in summer (Labor day weekend).
Cliffs on West side across from Sandy Beach, vis to 30' down was about 15', vis at 97' was around 3', but is dependant on light.
Perch Lake in Santa Rosa, Best vis on a FW Dive to date. Vis was 50'+, but was in March or April, water was 55* at 50'+. Very cool cliff faces, all hydro thermal rock deposits from hot water vent (no longer active vent). Lake has a Beach Craft plane in it and a car of some kind with a dive platform above it for training.
