A study of the water quality changes of NigeenLake was conducted for 6 months, which began in August 2010to Feburary 2011. Three sampling stations were selected representing the different areas in the lake. A total of 11 water quality parameters were measured. The physical and chemical variables were temperature, dissolved oxygen, conductivity, pH, total dissolved solid, turbidity, ammonia-nitrogen, nitrate-nitrogen and ortho- phosphate . Due to siltation, encroachment and pollution the lake has become shallower and the lake shore has turned into marsh at various places.The higher ranges for Sp. Conductance (192-560 µScm-1 @ 250c), Total-Alkalinity (106-435 mgI-¹), Calcium (29.6-44 mgI-¹), Nitrate-Nitrogen (275-931 µgI-¹), Ammonical-Nitrogen (38-360 µgI-¹), Total-Phosphorus (122-722 µgI-¹) which exceed the permissible limits is a cause of concern. Hence, the water quality is found to be poor due to increased anthropogenic pressures from the catchment area.
