Physico-Chemical Characteristics and Phytoplankton of Morna Lake, Shirala (M.S.) India

ABSTRACT

Morna Lake is largest Lake of Shirala Tahsil in Sangli District, Maharashtra. It is constructed over Morna River in the basin of Krishna. Present study was undertaken to investigate the physic – chemical characteristics and phytoplankton composition of the Morna Lake. Physico – chemical analysis of lake water exhibited richness in nitrogen ( nitrite and ammonia) and orthrophosphates which favored the growth of phytoplankton. Dominance of Cyanophyceae in summer and rainy season and Bacillariophyceae in winter revealed distinct seasonal variation in the distribution of phytoplankton. The Lake was found to be moderately polluted and showed a trend of increasing eutrophication.
