19 The estimation of primary productivity was carried out two ways: by analyzing chosen factors influencing the production - 10 factors:  fertility of drainage basin,  lake situation in the basin of the river,  water exchange in a lake,  fertility of a main influent drainage basin,  phosphorus content,  nitrogen content,  calcium content  potassium content,  grade of stability of the lake,  active bottom area of the lake  hypolimnetioc oxygen content changes depending on the grade of stability by evaluation some of primary production indicators – 3 factors:by evaluation some of primary production indicators – 3 factors:  changes in calcium contents from spring pick to summer minimum lake,  changes in potasium content  water transparency in the lakes differing by range of epilimnion Patalas K The method of classification of primary productivity of a lake by point system, applied to the lakes of Węgorzewo district.
