Abstract :

The man- made Chitgar lake is located in the north-western of Tehran and was received its from Kan river in 2012. The water quality was investigated on 5 sampling sites during 2013-2014. Standard methods (APHA, 2005) were used for Analysis of water parameters. The results indicated that the mean monthly temperature of water were measured 18.4 °C with minimum 6.3 °C and maximum value 27.1 °C. The mean EC level was 373 ± 30 µs/cm. The mean monthly dissolved oxygen and total phosphorous were 7.8 ±1.2 and 0.035±0.010 mg/l, respectively. The mean of  chlorophyll-α was 1.59 ± 0.810 µg/l. In fish assessment eighteen species were identified in the lake, while 11 species were from Cyprinidae family and one species was native (Capoeta bohsei). The exotic fish species were dominant in the Chitgar lake.
