Seasonal Variations in Physico-Chemical Characteristics of Almatti Reservoir of Bijapur District, Karnataka State

B.B. Kaliwal; S.B. Hulyal
Almatti reservoir is one of the major perennial water resource located at about 63 km away from Bijapur is mainly used for drinking and irrigation. Monthly and seasonal variations of physico-chemical characteristics were studied from February, 2003 to January 2005 to study the various ecological parameters such as rainfall, humidity, air and water temperature, pH, electrical conductivity, dissolved oxygen, free carbon dioxide, total alkalinity, total hardness, calcium, magnesium, chloride, nitrate, phosphate, sulphate, bicarbonate, total dissolved solids. The study revealed that there exists seasonal fluctuations of the factor and from data it was also apparent that various correlations between the factors could be seen. However, it is obvious that the absence of significant difference between sampling stations for all these parameters in the Almatti reservoir indicated fairly homogeneous conditions and the water quality is also found to be homogeneous. Study also indicated that the water is quite suitable for irrigation and pisciculture.
