The results of 2005-2006 monitoring demonstrate that the reservoir is an eutrophic, dimictic water body characterized by weak summer stratification (max.
All lakes are dimictic and a strong thermal stratification develops in summer, while the depth of the epilimnion stays rather constant at about 2-4 m.
varies in the monomictic, dimictic, and polymictic lakes.
Lakes where this happens are called dimictic. In some lakes, called meromictic, the deepest water remains stagnant and never rises to the top;
Events after the spring melt are different in dimictic lakes, where free circulation or mixing of the water occurs twice a year, in spring and in autumn, and the water column is thermally stratified in the period between the two mixes.
The lake is dimictic, with a thermocline at 3-4 m, and lacks surface inlets or outlets.
