Temperature: Lake Crescent @ 100 feet in July

[alm]

I'm contemplating attending a Deep Class there; can someone look at their
logbook and tell me what to expect for a temperature at depth?

This publication

suggests it was around 46 F (7.7 C) at 30 meters in 1994.

Last summer, I did a couple of solo dives in Lake Crescent during July and August, just to wash my gear off on the way home from trips out to go diving at Salt Creek. The viz was great, although, not much to see in the water. Typical lake dive...

I noted around 38 degrees F at 110-120 feet, and a fairly obvious thermocline at around 70 feet or so. I was over splashing around at East Beach, if it matters...

Definitely a lot colder than the ocean
