Abstract
In order to assess the impact of combined effluents from distillery and sugar mill units of Nawabganj township (Gonda), on hydrobiology of Parvati Lake, the present investigation was made during August 1989 to July 1990 at four sampling sites. The result revealed that the waste water from these industries with high values of BOD, COD, TS, TN, Temperature, conductance and nil or low values of Do and free CO, caused a marked ill effect on water quality, planktons, macrophytes and fish fauna of the lake at its down stream zones.
