A dence growth of planktonic algae often involving just one or few species and usually imparting a distinct colour to the water body is referred to as “Algal Blooms”. This universal phenomenon is also termed as “Flowering of the water”. Bloom formation is atributed to the algal genera belonging to the classes Bacillariophyceae, Chlorophyceae, Cyanophyceae, Dinophyceae, and Euglenophyceae. In the present study the author came across three water bodies having blooms caused by the species of Euglena. These water bodies were studied for different physico chemical parameters like color ,pH, temperature ,Dissolved oxygen ,Biochemical oxygen demand, free Co2 ,carbonates ,bicarbonates, total alkalinity,hardness,total suspended solids, sulphates ,ortho phosphates. Phytoplankton analyses were also conducted to study the dominance of Euglena in water bodies. Very high concentrations of organic matter, bi carbonates, phosphates and chloride were the chief features of the ponds waters having Euglena blooms.
