Subject: Re: water temp. in Great Lakes
Rod,

In a message dated 95-09-29 08:36:51 EDT, you write:

I'll pretty much concur with Gary & Clifford, based on my experience in Lake
Superior.  Down deep, it stays pretty close to 37-38 degrees F, which I
believe is the temp at which water is most dense.  August is warmest, in
Superior the surface temp may reach 70 F, with one or two thermoclines at
varying depths depending on weather.  This summer it was about 50 F above 75
feet, and upper 60s F above 30 feet - we were sweating on the hangs!

>Where? Specifically, what is temp at 100, 200, 300 feet. Guestimate temp

 Temp at these depths is going to be _cold_  - very likely 37 degrees F, no
matter what time of year.  Maybe warmer at 100 feet in later summer.

Are you planning to do some Great (Lakes) diving?  What, and put your DIVER
status (per your measurement standard ;-) in jeopardy?
