What an effect how deep Carp go ?
A limiting factor on the depth at which you might find carp would be the depth of the thermocline. During the summer months, the deep reservoirs typical of the Ozark region stratify by temperature, with a pillow of warm, well-oxygenated water floating on top of a body of much colder water underneath. The two bodies of water don’t mix much. Organic decay eventually depletes the oxygen in the lower layer of water, which makes it tough for fish such as flatheads and carp to survive for long in that layer. We generally see them congregated just below the line of temperature difference (the thermocline), where they can quickly move up into the warmer layer to feed or breathe. In the winter, when falling surface temperatures equalize the temperature between the two layers, mixing again becomes possible, oxygen reaches the depths, and fish can go where ever they like.
