Thermocline already setting up

On lake Hawkins today. Pretty much all over the lake at 16-17'. I couldn't see it on the sonar but down scan showed it good. You could see where it was on the sonar by where all the fish were.
Has any other lakes started setting up yet?

Thought I noticed it on Athens, but the monsoon hit and I peeled out

I know that's right!!

I was fishing a tourney today. Thankfully I had a really good limit when it hit, so I sat it out in the truck for an hour, then resumed the fishing.

No thermocline on the lake I was fishing today.
