An Ecological Study on Some Phisico Chemical Parameters of Dah Puraina Lake of Saran

Abstract

During the first and second year of study the lowest air temperature was recorded in the month of January at all the sites . The air temperature showed positive and significant correlation with water temperature at all the sites. Chakraborty et ah (1980), Kant and Anand (1998) and Rawat et al. (2010) also obtained strong positive and significant correlation between air and water temperatures. Generally, the water temperature is influenced by air temperature and intensity of solar radiation. In the present study the lowest and highest water temperatures were recorded respectively in the winter and summer months. The highest water temperature (250C) recorded during the summer months might be due to higher air temperature and greater penetration of sunlight. The water temperature was low during winter and high during summer might be due to seasonal impacts at all the centers {Singh et al., 1999b).
