Chlorophyll a and nutrient concentrations have been measured weekly and year-round at five municipal water supply intakes in Lake Erie since 1976. The establishment of zebra mussels (Dreissena polymorpha) in Lake Erie in the late 1980's-early 1990's

Analyses of phytoplankton samples collected weekly and year-round at municipal water supply intakes in Lake Erie have shown a response to long-term changes in phosphorus loading and the more recent invasion of zebra mussels. Total phytoplankton densi

Changes in abundance, taxonomic composition and the seasonal succession of phytoplankton have been evaluated at seven stations in the vicinity of Nanticoke, east of Long Point Bay, Lake Erie from 1969 to 1983. No phytoplankton samples were collected

Changes in abundance and seasonal composition of phytoplankton of the Nanticoke area of Lake Erie have been evaluated at eight to thirteen stations from 1969 to 1978. Water clarity, chlorophyll, phosphorus and temperature values were also assessed. T

As part of the on-going study of water quality in the Nanticoke area of Lake Erie phytoplankton samples were collected at several stations from 1975 to 1978. An evaluation of the abundance and changes in seasonal composition of standing stocks of phy

Changes in abundance and seasonal composition of standing stocks of phytoplankton were evaluated at nine stations in 1972, 1973 and 1974. These data were compared to previously reported data from 1969 to 1971 (Michalski, 1972). Water clarity, chlorop

Limnological, bacteriological and biological data for Roblin Lake, a potential source of water supply for the village of Ameliasburgh, were collected on 5 days during the summer of 1970. Classical indications of mesotrophy and/or early eutrophy were
