Saturday, while I was fishing, I took water temps in the shallows, it was 51 degrees. I spotted several Tilapia in the shallows, they appeared ok and submerged as I approached.
I don't know what the deep water temps are, the jon boat is "high & dry" due to the drought...5-6 ft. low. I didn't want to make too much noise dragging the boat to water, I was Duck/Deer hunting too

Ponds are great ! I saw what appeared to be 2 Hooded Merganser's that were worthy of mounting...just couldn't get them within range...adding water to my property has produced 10 fold in return

if not more...
