according to KarlPearson’s formula. This study has provided the first data set for water quality of lake. The value of various physico-chemical parameter were temperature (90C to 310C), pH (7.1 to 8.3), electrical conductivity (127.0 µmhos cm-1 to 454.2 µmhos cm-1 , dissolved oxygen (4.5 mgL-1 to 12.5 mgL-1), free CO2 (3.08 mgL-1 to 12.32 mgL-1), alkalinity (70 mgL-1 to 161.6 mgL-1), acidity (2.4 mgL-1 to 68.0 mgL-1), Hardness (56.8 mgL-1 to 148.6 mgL-1), total dissolved solid (127.4 to 782.2 mgL-1), total suspended solids (24.0 mgL-1 to 371.2 mgL-1), salinity (82.0 mgL-1 to 421.4 mgL-1), nitrate(1.0 mgL-1 to 5.78 mgL-1), phosphate (0.004 mgL-1 to 0.022 mgL-1), biological oxygen demand (2.04 mgL-1 to 8.98 mgL-1 ), chemical oxygen demand (4.4 mgL-1 to 9.08 mgL-1) and sulphate (3.9 mgL-1 -21.0 mgL-1).Dissolved O2 showed positive correlation with Ca hardness and negative correlation with temperature, TDS, TS, acidity, nitrate and sulphate. TDS showed a positive correlation with TS and sulphate. All the physico-chemical factors studied except BOD studied were found within the permissible limit for drinking water as recommended by Bureau of Indian Standard (BIS). The lake was found to be slightly eutrophic during monsoon months. Main reason was nutrients and other organic matter from the agriculture fields in the catchment area are brought to the lake due to influx of rain water." />

Water quality of Siliserh lake was studied for period of one year on the basis of monthly sampling. Correlation between various physiochemical parameters were also calculated according to KarlPearson’s formula. This study has provided the first data set for water quality of lake. The value of various physico-chemical parameter were temperature (90C to 310C), pH (7.1 to 8.3), electrical conductivity (127.0 µmhos cm-1 to 454.2 µmhos cm-1 , dissolved oxygen (4.5 mgL-1 to 12.5 mgL-1), free CO2 (3.08 mgL-1 to 12.32 mgL-1), alkalinity (70 mgL-1 to 161.6 mgL-1), acidity (2.4 mgL-1 to 68.0 mgL-1), Hardness (56.8 mgL-1 to 148.6 mgL-1), total dissolved solid (127.4 to 782.2 mgL-1), total suspended solids (24.0 mgL-1 to 371.2 mgL-1), salinity (82.0 mgL-1 to 421.4 mgL-1), nitrate(1.0 mgL-1 to 5.78 mgL-1), phosphate (0.004 mgL-1 to 0.022 mgL-1), biological oxygen demand (2.04 mgL-1 to 8.98 mgL-1 ), chemical oxygen demand (4.4 mgL-1 to 9.08 mgL-1) and sulphate (3.9 mgL-1 -21.0 mgL-1).Dissolved O2 showed positive correlation with Ca hardness and negative correlation with temperature, TDS, TS, acidity, nitrate and sulphate.
