INTRODUCTON
Sagar lake is situated on 23° 50' North and 78° 45' East . It is about 517 meters above sea level and surrounded from three sides by ghats and houses except the southern side . The average rainfall is 46.4" . The peak winter months are December, January and February, and cool nights have an average minimum temperature of 7 °C. Peak summer temperature is 43 °C. It is a rain-fed lake with an area of 200 acres .
Increasing macrophytic vegetation and silting on all sides has resulted in gradual loss in water capacity and the bed is rising . The lake is maintained by the Fisheries Department for pisciculture and the main fishes cultivated are Catla catla (HAM) ., Labeo rohita (HAM .) Cirrhina mrigala (HAM .) .
Only taxonomic studies of the macrophytes of the lake have been done so far without limnological recording . This paper deals with the limnological aspect of the lake .
