62 on the surface. 59 at 30' in Cornwall near the rcaf boat launch. Vis was awaful today.
 
Just got back from a Trimix class on the river. Water Temps were -

6/6 islander - 57
6/7 Vickery - 55
6/7 Keystorm - 56
6/8 Vickery - 55
6/8 Maggie L - 55
6/9 Jodrey - 54
6/10 Jodrey - 54
6/10 America - 56
6/11 JB King drift - 56


Vis was all pretty good ranging from 25 - 35 feet most of the time.


Temps listed at depth and 2 degrees reduced for the average correction needed on my Petrel - then confirmed with a Nitek DUO. Difference between surface and depth was only 2 degrees expect on the Jodrey where the little cove was warmer on the surface until about 15 feet.
 
Was raining but great drift dive between the boat dock and the beach in Morrisburg.

Vis was decent for the weather we were have 10-15 temp was 61 at 50'.
 
Keep those temperatures coming, I'll be there on the July long weekend, and haven't seen 60 plus temps since last summer.
 
Hitting around 64-66*F on my computer, thru the Morristown, Brockville region Wednesday 7/3. Weather this year has definitely slowed warming and vis is less than last year.
