Lake Turn Over...

[k-valve]

Lake Turn Over. It's one of those things you recognize when you see it, but it's hard to define...at least for me. After diving this weekend in the current low-vis of Lake Travis (after being spoiled with awesome vis all summer) it dawned on me that the lake was probably beginning to "turn over". When that light went off in my little brain I decided to find a decent description of what causes, and happens when, a lake turns over. For the geeks among us (me included) check out these two web pages. They do a good job describing the process in terms that even I can understand.

Interesting stuff...... I Like it .

I can usually tell when the lake turns just by how the local water tastes


Somedays... I can close my eyes and take a drink and almost have to equalize my ears

Florida Lakes never produce an isotherm so we never get a Fall or spring turn over. Unfortunately, this means that we accumulate a TON of sediment at the bottom of all of our lakes. I have heard that Lake Okeechobee has accumulated muck up to 200 feet in places.

I dove Crappie Point at Tenkiller Lake last Sat. and there was no thermocline, at least not one down to 80'. The surface temp was 70 degrees. At 15' to 80' temp was 66 degrees. Gene said he thought the lake was getting ready to turn over.
