That murky water tells you it's time to change techniques.
Anglers are interested in lake turnover because they know it can foul up fishing.
But from what I've seen, the mechanics of the turnover process and exactly how it affects fish might be the least understood aspect of freshwater fishing. Okay, so there's a little more to it than that. Before you can understand the turnover phenomenon and what it does to fishing, you need to know about some of the unique physical properties of water. With these properties in mind, the mechanics of the turnover become a lot less murky. The temperature layers remain intact through the summer as long as the air temperature is warm enough to keep the surface water several degrees warmer than the water in the depths.
