The Acid Sensitive Lakes Study in the Atlantic Canada was initiated in 1983 by Environment and Climate Change Canada, to evaluate the impact of acid atmospheric pollutant on aquatic ecosystem. Originally, the study focused on the aquatic and terrestrial effects of acid precipitation, but now it...

The Turkey Lakes Watershed (TLW) is 1 of 5 hydrologically "calibrated" basins in eastern Canada that were originally devoted to process-oriented research into "acid rain" effects. They were selected to cover a wide range of climatic and hydrological conditions, deposition magnitudes, and terrain...

The surface water quality (WQ) program, as part of the Joint Canada/Alberta Implementation Plan, is designed to improve the ability to detect change and predict effects in relation to point and non‐point sources. A mass‐balance approach has been used for assessing the quantity, movement, and...

Hamilton Harbour is located at the west end of Lake Ontario. It was designated as one of 43 Areas of Concern in 1987 under the GLWQA where 11 beneficial uses of the harbour were deemed impaired. One of the primary recommendations of the Hamilton Harbour Remedial Action Plan was to decrease...

This dataset contains annual algal bloom indices (duration, extent, intensity, severity) summary statistics (maximum, mean) over the June through October monitoring period for Lake Winnipeg. These data are derived from satellite remote sensing algorithms using European Space Agency's (ESA's)...

This dataset contains annual algal bloom indices (duration, extent, intensity, severity) summary statistics (maximum, mean) over the June through October monitoring period for Lake Erie. These data are derived from satellite remote sensing algorithms using European Space Agency's (ESA's) MEdium...

The Pulp & Paper Effluent Regulations (PPER) were published in 1992 pursuant to the Fisheries Act to control effluent discharges and reduce the impacts of effluents on fish and fish habitat that had been observed at pulp and paper mills across Canada at that time. The Regulations set out...

Hamilton Harbour was designated as one of 43 Areas of Concern in accordance with Great Lakes Water Quality Agreement (GLWQA). Ten out of eleven Beneficial Use Impairments were identified by the Remedial Action Plan (RAP). The RAP is an ongoing collaborative effort implemented by federal,...
