On 7-17-07 me and a buddy went diving in Summit Lake in Hatcher's pass. The water was quite cold, 45-40F within the first ten feet, and a thermocline dropping to somewhere in the 30's below that. I wore my 9mm two-piece wetsuit, and was warm enough above the thermocline, but got pretty cold below that, particularly on the hands (no gloves) and around my mask. Above the thermocline, vis was pretty good for a lake-around 20 feet or so, but below that it dropped to about 5 feet because of some weird, briney, algeaish goo in the water. Also, below the thermocline there was clouds of little black waterbugs that looked like little dots swimming around. Above the thermocline in warmer water there were tons of litte shrimp critters about an inch long swimming and digging in the softer substrate. Most of the lake bottom was rock, with soft dusty mud that had settled in places.
Good dive.
