Abstract
The heaviest algal bloom that can be expected in an aquatic system was formed in a waterchestnut ecosystem in Lake Kasumigaura during the summer in 1978 when the water temperature was greater than 30°C, caused by the nutrient discharges from the River Koise and the River Sanno. The heavy bloom not only threatens the steady-state equilibrium of the eutrophic system of the Lake but also must accelerate the Lake transformation into a low moor by forming ooze on the lake bottom with the precipitation of a large amount of dead blue-green algae.
