We have had a lot of days where it got cold for a week and then the air temperatures jumped back into the 70's. But the lake surface waters can warm back up if it gets warm again. Now a lake that has a lot of different bays and depths can have turn over in different areas over a period of time.Īlso this time of the year the lake water is cooling off or going into a cooling trend. Oil being lighter and will float on top of the hot water because it less dense. And yes hot water is less dense than cold water. ![]() Hot water is more buoyant that cold water. Water temperature effects the density or you could say the buoyancy of the water. It all depends on the water temperature though out the water column in a lake. Just wait for a week after and watch for groups of shad. If you have to do, fish slowly and fish a lot of water. So therefore, forgettabout fishing during turnover. About 1-2 weeks after the turnover and after the lake settles, the fish will generally move into a fall feeding frenzy chasing shad. Turnover is generally a stressful time for fish and their metabolisms generally shut down during turnover, and coupled with the scattering, makes fish very hard to catch. Therefore, fish can survive at any depth in the lake during this time and are, thus, very scattered. After turnover, all levels in the water colum have virtually the same temperature and oxygen levels. For example, during the summer, from 0-15 feet, the tempuratures and oxygen levels are pretty constant, and from 15 feet deeper, the temperature and oxygen levels are much much lower. After turnover, themoclines are non-existant, they are a summer phenomenoa. Turnover causes the oxygen and temperature levels throughout the water colum to be equal throughout. ![]()
