Abstract :Lake Nazik is located in 1816 m above sea level and in 38 0 51’ N 42 0 14’ E coordinates. In this study, to identify the value of monthly chlorophyll-a, ENVISAT/MERIS satellite images were used. On the other hand, MODIS/Aqua satellite images were also used to identify the value of monthly surface water temperature. Carrying capacity of lake was identified as 24100.21 tons/year, and an annual average chlorophyll-a value was found out as 7.12 mg/m 3 . Using data on ENVISAT/MERIS satellite images, it has been observed that the chlorophyll-a concentration in Lake Nazik reached its highest value of 30.071 mg/m 3 in September, while dropping to its lowest value of 3.727 mg/m 3 in January. Using data on MODIS/Aqua satellite images, it has been observed that the maximum value of water surface temperaturewas 22.89 C 0 in August, while the minimum value was2.33 C 0 in December. Furthermore, it was found out that theannual average value for water surface temperature during the study was 14.9 C 0 .
