Abstract :

This paper presents the study of Physico–chemical Parameters of lake Himayat sagar to ensure appropriate water quality monitoring and management for future planning of clean water resources. Lake water quality parameters like pH, turbidity, alkalinity, Total solids, conductivity, calcium, magnesium, sulfate, BOD, DO, etc., were investigated. The study was carried in three months demarcating pre and post monsoon for a period of one year (2011). Water from twelve sampling locations was examined physico–chemically and most of the parameters were observed to be within (BIS) IS: 2296–1982 Surface water quality standards limits. However, water colour was slightly greenish with 40 Hazen units of max.value, average pH ranged between 8 to 8.5 indicating alkalinity and DO value varied between 3.2 mg/l and 8.0 mg/l with corresponding BOD values of 3.8 mg/l and 2.0 mg/l indicating contamination by high organic load into the lake.
