When its about 87 degrees or less, there is no water flowing out of the lake, and the lake is pounded with tournaments and normal fisherman, where do you go? This lake is the toughest around my area and the hardest hit. I’m not really sure where to fish on the lake because it is new to me, but those are the conditions most of the time. Do you go on points, up in coves, in the creeks or what?
I would work the shallows in the morning and then work your way out to the deeper water (points). If you know the travel routes of the fish, thats the best place to target. Ledges, humps, points are all good spots to run a C-rig, jig, spinnerbait, deep crankbait around.
I was never really into jigs either until I started using them only in the perfect conditions. I got comfortable with them and now if I see some fallen timber or tight cover, I do what I’m doing all around the cover and then grab my jig rod and toss it in.
I would be fishing in the 6-10 ft. range. Throw fast moving lures at dusk, dawn and nighttime and a slow presentation during the heat of the day. This would be my guess based on what you said the conditions are. Good Luck!!
If this lake is high pressure then your best bet for catching better quality fish is to go deep, or at least fish near deep water. You should still be able to catch fish on the shoreline cover but most likely they will not be the bigger fish. If you have a depthfinder pull out to the channels, points, humps, ledges and start looking for the baitfish. The bigger fish shouldnt be far behind them.
