Hypertrophic-eutrophic alteration in Kandy Lake, following an outbreak of a Microcystis bloom

Urban water bodies especially those located in the humid tropics are vulnerable to high anthropogenic pressures although their uses are tied up with hygienic and economic conditions of the riparian communities. An aesthetic water body located in the hill capital (Kandy) in Sri Lanka was subjected to long term monitoring of chlorophyll-a and Secchi depth and other environmental variables following an outbreak of Microcystic aeruginosa bloom in May 1999. The episode of hypertrophic-eutrophic alteration of in Kandy Lake is discussed here in relation to monsoon-bound rainfall events and other environmental variables.
