Studies on Physico-chemical Parameters of Ambawade Reservoir, Raigad District, Maharashtra, India

The present study deals with physico-chemical parameters and their correlation coefficient of Ambawade reservoir, Raigad [M.S] India during February 2014 to January 2016. The range of various parameters of reservoirs atmospheric temperature from 25.3ºC to 36.4ºC, water temperature from 23.5 to 35.7ºC, pH from 5.80 to 8.40, DO from 4.56 to 8.32 mg L-1, transparency from 32.56 to 103.40 cm, Free CO2 from nil to 5.90 mg L-1, EC from 58.20 to 110.80 µS cm-1, TDS from 8.41 to 18.42 mg L-1, total hardness from 54.40 to 71.32 mg L-1, total alkalinity from 46.32 to 74.21 mg L-1, NO3 - -N from 0.378 to 1.024 mg L-1, PO4 -P from 0.041 to 0.310 mg L-1, SiO2 from 3.75 to 9.19 mg L-1, Mg2+ from 5.67 to 8.84 mg L-1, Na+ from 3.04 to 5.66 mg L-1 and K+ from 0.36 to 0.98 mg L-1. Correlation coefficient (r) showed high significant positive and negative relationship (p < 0.01 level) between the parameters. The results revealed that there was a fluctuation in physico-chemical parameters during the period under report.
