Abstract Plankton was studied seasonally and quantitatively in Long Pond, St. John's, Newfoundland. This pond receives both rural and urban runoff and is characterized by a high flushing rate. A comparison is made with Clarkes Pond, Hogans Pond and Bauline Long Pond. Long Pond phytoplankton was characterized by nannoplankton (particularly flagellated forms). The most important zooplankters were Bosmina coregoni and Daphnia catawba . Aspects of plankton ecology are discussed in relation to eutrophication and water renewal.
