Was on the water at Clarks Hill this morning and guess what? It was cold. At the ramp the temp. was 25 and ice all over it. Wind blowing 15+ makes wind chill around zero. Eyes on the rod were iced as was the reel. Even when the sun came out it was not until about 10 that everything stopped freezing! If you threw a jig and put it down it froze. And the water? Was as dirty as Livingston in Texas (Hersey) in the spring and was 44 degrees.

Fun morning. We will see how the tourney goes tomorrow.

Use your elecronics and locate the thermocline and fish it!!! It's only cold on the surface, the bass will seek the warmest water available where there is prey. Dress warm and Good luck

Sorry Tom . Now I am confused. Thermocline ? Doesn't the water stratify only in the summer? Isn't cold water more dense causing it to sink. Please elaborate. Thanks.

After the turnover there is no thermocline. Water is like air, warm rises. The warmest water is near the surface where the sun can warm it. I especially like dirty water as t warms fastest. However, right now, stained is better, as the sun has not been out enough to warm the dirty water. Hershey brown, COLD water is the worst possible condition. I will be fishing stained tomorrow rather than dirty, we will see.

Thermoclines are traditionally linked to summer stratification in northern natural lakes that freeze over. The ice melts and spring turnover follows, the surface water warms creating the upper epilimnion layer, then the deeper water cools down rapidly creating the thermocline or metalimnion layer or summer stratification.
Winter period in a deep highland reservoir is very deferent than a northern natural lake. The warm summer water slowly cools down and sinks through the warmer upper layers, cooling down the water column. The heavier cool water presses down a layer of warmer water that is trapped between two colder layers, the winter thermocline or life zone for bass during the cold water period. Some bass will venture up to sunny banks during the cold water period to feed on cold water prey fish, however will move down to the warmest layer with sufficient DO, dissolved oxygen, and prey fish the majority of the time. The exception to this is in shallow lakes, rivers and power generation lakes where the water has current or too shallow to layer.
This is why it is very important to have good electronics during the winter period to locate the "life zone" where the deep bass are holding. The deep highland or hill land reservoirs commonly have bass schools holding in water 40 to 60 foot depths that go un fished during the cold water periods. Dirty or muddy surface water is just that, dirty surface water and for me something to be avoided during cold water periods, unless it is the warmest water available.
