Abstract: Present study has been carried out in Tekanpur Lake to study the physico-chemical water quality and primary productivity to assess its production potential. The study area was divided into 5 sampling sites to cover the whole lake area comprehensively. The parameters taken were pH, Conductivity (μmho/cm), Turbidity (NTU), Transparency (m), Total Hardness, TSS (mg/l), TDS (mg/l), Total Alkalinity , Free CO2(mg/l),DO (mg/l),BOD (mg/l), COD(mg/l), TN (mg/l), Nitrate-N (mg/l), Nitrite (mg/l), TKN (mg/l), TP(mg/l), Fluoride (mg/l),primary Productivity(mg C/m3(/d) & Chlorophyll-a microgram/l. Trophic Static Index of Tekanpur Lake was computed using regression equations and Carlson trophic status classification criteria was followed to know the status of the lake and The water quality criteria developed by CPCB have been used for classifying the lake water quality(class of water).The variations of each particular parameter across stations and that over seasons or years were calculated using the correlation and t-test.
Keywords: Primary productivity, Phytoplankton, Trophic Static Index, correlation, regression equations.
