Abstract

Limnological studies of Keenjhar Lake were carried out during January 2003 to December 2005. The present study deals with physico - chemical parameters such as, temperature, pH, alkalinity, chlorides, conductivity, total dissolve solids, turbidity, dissolve oxygen, calcium and magnesium. The maximum and minimum range of physico - chemical properties were as, temperature 18 - 33 ⁰C from station 2 in January and August respectively, pH 7.3 - 8.9 in September and June respectively, alkalinity 160 - 240 mg L-1 in July and January respectively, minimum chlorides 30 mg L-1 in September and maximum 85 mg L-1 in December, conductivity 320 S cm-1 in September and 496 S cm-1 in December, total dissolve solids were 240 mg L-1 in September and 391 mg L-1 in October, turbidity was 30 NTU in December and 78 NTU in May, dissolve oxygen was 7.0 mg L-1 in January and 9.0 mg L-1 in July, calcium 50 mg L-1 in July and September and 78 mg L-1 in October, magnesium 21 mg L-1 in August and September, 35 mg L-1 June, and it is concluded that the variation in parameters were due to rain and flow of  River Indus.
