Plummeting water temps in summer

Featured Replies

Yes it's another water temp question, but things have been so screwy here that I have to ask.  I am familiar with swinging water temps in spring and fall but I've not fished through what is going on now.  If you saw my last post in the catch thread I was exclaiming about water surface temps being above 90 in the afternoon.  That's pretty high here.  I usually don't see anything above 87 or 88.  Well now we have had four days of on/off chilly rain and air temps have gone from highs of 88 to highs of 72.  I just checked water data online and the surface temps have dropped 4-6 degrees in the past four to five days.  I have to assume that the water is high and muddy from the influx also.  

 

I've never seen a drastic drop like this in our hottest time of year.  This is usually drought.  I'm going out tomorrow and my gut is telling me this is a good thing and shallow, loud moving baits may be the deal.  Am I way off?  Am I more likely looking at something more like a lake turnover?  I think the plague is now affecting the weather.  Any thoughts are appreciated.  

 

UPDATE:  One of the two lakes I fish most frequently has turned over on the shallower north end.  Fish kill.  That sucks.

Surface temps have been 81 last couple weeks. Only one day last week temp was 72. I thought depth finder was screwing up so I turned it on/off a couple times. Nope still 72. Next day back to 81. 
Lake turned over I guess

Surface temps are just that. On the surface. A foot or two down, the water temperature hasn’t changed much. I wouldn’t make any big changes just because of the surface temps. But, you never know what fish are going to do on a given day.

Big cool snaps during the summer months rarely produce good fishing in my experience. It always sucks because I get so hyped up to go out in the nice weather, then get beat down by the bad fishing almost every time.

 

It's highly unlikely your lake turned over from that minor of a temperature drop though.

200 miles to the west,  with very similar weather patterns have moved the shad shallow and the bass are feeding heavily . This was on a cloudy , drizzly day . A sunny day might make it tougher and position the shad deeper and  the bass deeper  in cover .
