Physico-chemical parameters in Rana Pratap Sagar dam (RPS) and Chambal river l.e. temperature, conductivity, depth of visibility, total dissolved solid, chlorides, total alkalinity, total hardness, nitrate, phosphate, silicate and primary productivity were observed. RPS dam and the Chambal river were well within the permissible limits for drinking water recommended by WHO and Indian Standard parameters for public water supply, fish culture as well as irrigation. Moderate fauna of total 30 forms of phytoplankton (40%, chlorophyceae), 18 forms of zooplankton (38.88%, rotifers) and 22 forms of benthos (27.27%, gasropods) were reported in RPS dam whereas in the Chambal river total 26 forms of phytoplankton (44%, chlorophyceae), 21 forms of zooplankton (33.33%, rotifers) and 23 forms of benthos (26.08%, gastropods) were identified. On the basis of productivity the RPS dam showed eutrophic characteristics as compared to the Chambal river which was showed mesotrophic nature.
