I went fishing Saturday. The creek that we started fishing in had spots every 8-10 feet that had bubbles coming to the surface. Columns of them. Not small aerator sized bubbles. Nickel/quarter sized bubbles. I could see them on my DI and SI too, coming up from the bottom of the lake. Acres and acres of this going on.
Is that a sign that the turnover is happening? If not, anyone got any ideas what that was?
I witnessed the same thing in some shallow creeks here Sunday.
It could be methane gas from decomposing matter in the muck and silt on the bottom.
I did see a lot of suspended algae for lack of a better word in the creeks that had tons of bubbles
Saw that in the creeks of the lake I fished last week, just not those sizes of bubbles. I don't think it's a sign of turnover, around here anyway, as the surface temps are still in the mid 70's (and in many cases the temps are the same down to nearly 15-20ft deep).
Water temps here have dropped around 9 degrees in the last week. It was our first good cool snap
Earthquake !!!
I don't think it has anything to do with a "turnover" of the water. First of all, flowages (creeks being a flowage) don't usually stratify with a thermocline. Moving water keeps it pretty well mixed, top to bottom. Consequently, the water never really turns over, the way it does in large lakes and some deep reservoirs. At least that is what I've always been taught.
I can't speak for FurFlyin. My creek is part of a TVA hydro lake I had not thought about water flow not allowing a lake to stratify. The lake level was being lowered to winter pool level. Around 3 feet of water had been drained from the lake. The act of lowering the water level may have caused the algae to become dislodged and floatingQuote:
