Abstract :

 

The present study assessed the seasonal variations of the selected water quality parameters of Sompura lake from January 2010 to December 2010. The range of the selected water quality parameters were observed to have a seasonal significant difference for temperature (27.5–34.5ºC), pH (7.2–8.6), Turbidity (15–63 FAU), Total dissolved solids (400–1100 mg/L), Electrical conductivity(625–1718.75 μmhos/cm ), Dissolved oxygen (5.2–9.1mg/L), Biological oxygen demand (2.28–7.34 mg/L), Chemical oxygen demand (5.68–9.82 mg/L), Chloride (58.72–112.6 mg/L), Alkalinity(44.8–112.2 mg/L), Hardness (84–154.4 mg/L), Phosphate(1.23–2.43 mg/L), Nitrate(5.12–8.9 mg/L) and Sulphate (19.8–32.5 mg/L). The results obtained from physico–chemical analysis were compared with WHO standards. In the present study all the parameters were found to be within the permissible limits, while phosphate was found to be beyond the limit. But availability of dissolved oxygen clearly evidenced that Sompura lake is suitable for fisheries. Correlation analysis was made using SPSS software.
