Density Stratification of Lakes. Water masses will layer in order of increasing density with depth. Any denser water at the surface will sink to a depth of equal density or to the lake bottom. Sinking denser water (convection currents) and wind waves create turbulent mixing of water masses.

Density Stratification of Lakes
Causes & Profiles
Seasonal Circulation Patterns
Large amounts of energy are needed to “breakdown” a well established thermocline. It is a barrier to eddy transport of solutes (like nutrients) from the hypolimnion and slows the sinking of particles from the epilimnion.
The TDS profile would show an increase with depth. This is a desert pond, as water evaporates a the denser saltier brine sinks to the bottom, taking heat with it.

E.g. Mountain Lake, VA, a temperate (30º- 60º N or S) dimictic lake
Conductivity is the inverse of current resistance; more ions (salts) then greater values.
