What are the three common types of lakes based on stratification patterns?

The three common lake types based on stratification patterns are polymictic lakes, dimictic lakes, and monomictic lakes. 

The different zones in a lake include the littoral zone, pelagic zone, epilimnion zone, metalimnion zone, hypolimnion, and profundal. Each of these zones contains habitats that aquatic organisms use and relate to how the lake functions.

Water residence time, or WRT, is the average time required to refill a lake basin with new water if it were to be emptied. This amount is generally measured in years. Knowing the rate at which water can be replaced is critical to determining how quickly we can consume it.

The maximum operating level of a reservoir is the highest elevation that the water level should reach during normal operations, while the spillway elevation is the elevation at which water will begin to flow out of the reservoir and into the spillway and river below. The spillway elevation is always below the maximum operating level … Continued
