heres a puzzler....

[Embrey]

went out yesterday...lake at 39 degrees and seen up to 41 in spots . fast forward to this morning...41 at the first spot i fished. then went a couple miles around where i was yesterday...45. fished a little more, then i started seeing 48...then 50. at one point i seen 52. at this point i think my humminbird has went wacko. until i went back to where it was 45 and its still 45. end of the day, im back where i started and showing once again...41... so, pretty sure i just witnessed a turnover starting even though it supposedly had already happened. either that or i was too cold to see straight. makes sense though. yesterday i at least had a fish on and knew i was on top of them. today was horrible and never found anything to speak of at all. thoughts?

Turnover has already occured back in Oct.

What you are seeing is warm spots on the surface waters. The top layer can warmup but it will soon mix with the deeper water.

Water is heated by the warmer air and waves and the sunlight starting at the surface in deep water and along the shallows of the lake where there is dark bottom. But the wind and waves will distribute this warmth thoughout the lake this time of the year.

Actually once the surface ices over the warmest water will be at the very bottom of the lake in the deepest spots. Water is denser at 39 deg F than at 32 deg F. One of the reasons why the ice starts forming at the surface and not at the very bottom of the lake. Ice floats as it's lighter than water.

yeah...hmmm..im not buyin that... reason being,there was very little sun yesterday ,and 41 at the most when i left at dark. and lets say the sun DID warm it up just for fun. it didnt warm it 13 degrees from 6 last night to daylight this morning. and even if it did, there wouldnt be drastic changes as close together as they were. need more input

[idbefishing]

Perhaps, warm rain? were you in a creek?

[Embrey]

ha...no...big lake...and no rain whatsoever

Turnover happened long ago. We had the 5th coldest October on record. Almost every day was below normal, and significantly below normal. November was only normal for 16 days.

All lakes are in deep winter pattern already, almost iced over on some central Indiana lakes.

The only other explaination I can think of is that your temperature gauge is mess up and not accurate or precise.

Take a bucket of ice water and put the probe in the bucket and see if it reads 32 deg F. Then take some water in a metal bucket and heat it up to boiling or close to boiling. Will your temperature gauge read 100 deg C? or 212 Deg F? If it can read that high then stick it in the boiling water and see if it reads 212 deg F. If that's too hot you can beg borrow or steal a NSTS certified thermometer and use that to compare the readings that your temperature probe or gauge is giving you.

It's not what Scientists and Fishery Biologist would call Turnover.

You would have to have layers of water in the lake with a large temperature difference to have turnover happen.

From what you told us that's definatly not the case here.

You would know this if you had a temperature probe that you can lower down though the lake into the dephs from the surface to the lake bottom and back up. That would give you the lakes temperature profile.

The corp of engineers does this for Patoka Lake and they post it on their web site during the summer months. But they stop taking the measurement when it gets too cold. And that's long after the lake has turned over.

Sorry you don't believe me. But a lot of electronic gauges or equipment are effected by temperature changes. The depth finder or the other electronic equipment that interupts the gauges electrical signals can be effected by cold weather. Cold being 40 deg F as compared to 95 Deg F in the summer months.

yes i know its turned over already. i know this isnt an actual turnover , but something went on. my temp guage has read fine all year and did the PREVIOUS day as well. and all the temps repeated when i went back to the spots that were drastically different than other places. so the guage is working. actually its only a few months old. and i can lower my probe down,although only about 10 ft.all i know ,is the sun and the weather wednesday didnt raise the surface temp 13 degrees in spots.

Springs?

[Moveon]

Springs?

That's a possibility. But generally underground springs have cold water. But the underground springs may still be warmer than 32 deg F. They could well be in the 50 deg range. That warmer water would rise up though the 32 deg water and end up at the surface. It would be diluted by the cooler surface water though.

My main concern was that people didn't think it was the lake turning over in Dec.

What type of temperature gauge did you use. I am curious now.

[Embrey]

doubtful springs...many thousand acre lake. and using the guage on my depth finder...humminbird matrix77
