Thermal and chemical stratification is a common phenomenon in lakes and ponds during the summer months. Most lakes, 20 or more feet deep, have a warm epilimnion separated from the colder deep water stratum, the hypolimnion, by a thermocline or zone in which the water rapidly becomes colder with increased depth.
