The thermocline may represent a temperature change of 1°C for every incremental depth of 1 metre of water. In inland water ecosystem: Permanent bodies of standing fresh water. The arrow is used to show the movement of wind over the surface of the water which initiates the turnover in the epilimnion and the hypolimnion. Between these two layers is a mid-temperature range layer known as the metalimnion and this is where the thermocline is located (notice the green line in figure 1). The retention potential may be very low for some reservoirs, depending mainly on factors such as dissolved oxygen concentration, light penetration, water velocity, stratification, height of water outlet, and epilimnion and hypolimnion depths. Progressive erosion of the metalimnion occurs by entrainment, with a corresponding lowering of the thermocline level (Mortimer, 1961).
