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.
