The variation of several water quality indicators in Red Lake. The natural dam lake from the Hăşmaş Massif is supplied by four permanent streams and various torrential courses. Lake water quality parameters are influenced by natural factors of the region, and the touristic activity of the Red Lake Resort. Evaluation of the water body was done on water samples taken in four sampling campaigns/year. Samples were taken from the middle of the lake, at the water surface. The analysis covers two periods separated by an interval of 11 years: 1993-1999 and 2010-2015. Along with the temporal indicators evolution was analyzed also the standard deviation variation. Deficiencies in respect of employment in quality standards were observed at total phosphorus, total nitrogen, and dissolved oxygen. Regarding total phosphorus, which expresses the degree of eutrophication, the lake water was mesotrophic in the first period, and in the second became oligotrophic. In the future this lacustrine ecosystem requires greater protection to prevent more drastic degradation of water quality.
