The weekends before and after the July 4 I was diving both ends of Lake Superior and found the temps to be unseasonably warm and the vis. bad, about 1/2 what it usually is. Even people on the beach were saying the lake seemed warm this year. One fellow offered that they'd had an incredible amount of rain, which was backed up by very high inland lakes. This rain brought warmth and junk into the water which goes in Lake Huron, then into the zebra muscle feeding frenzy filter. So, if you have warm temps and good vis. in Kingston, I'd say the lower lakes are the place to be although the wrecks in Superior are wonderful and vis is still a respectable 15-20ish ft. The sun makes a big difference too.

It's those >damn Zebra mussels. I just got back from a weekend in Kingston, and we were getting that sort of awesome visibility. For the first time ever, I actually saw the whole Munson from one vantage point. I don't think the warmth ran quite that deep; there was a decent thermocline around 45', but deco was in nice warm water. In a way it doesn't make sense: a few weeks ago when we were doing the Morrell and the Dundenberg (Lake Huron, just off the Michigan "thumb"), upstream of a lot of the civilization in the Great Lakes watershed, out of sight of land, the viz sucked, but right at the downstream end of the bottom lake, only about a klick offshore, we get great viz. Those zebra mussels must sure suck a lot of shit out of the water, because they're the only reason I can think of for Kingston having the better viz. Now if the little buggers could just leave the wrecks alone, we'd have something going. -- Anthony DeBoer http://www.onramp.ca/~adb/ adb@he*.re*.or* (here) adb@ge*.co* (work) #include "std.disclaimer" -- Send mail for the `techdiver' mailing list to `techdiver@terra.net'.
