WCPS-coupled forecast is the component in the Water Cycle Prediction System (WCPS) that provides the coupled atmosphere-ocean-sea ice forecasts at a 1km resolution (0.008 x 0.008 degree) over the Great Lakes, St. Lawrence River and the Gulf of St. Lawrence. It launches 4 times a day at 00, 06,...

Since 2009, the Watershed Hydrology and Ecosystems Research Division of Environment and Climate Change Canada (ECCC) has coordinated spring time multi point ice thickness and composition surveys at up to 15 lake sites in the Northern Hemisphere. Data collected includes on ice snow depth, total...

In 2016-2019 water samples were collected at Lake of the Woods as part of a research program to determine sources and fate of nutrients in nearshore areas. These included samples of lake water, groundwater, streams, and septic wastewater. The samples were analyzed for nutrients (total and...

One component of this initiative aims to improve current understanding of nutrient dynamics and cyanobacterial and harmful bloom (cHAB) occurrences on Lake of the Woods. Research will focus on investigating the sources of nutrients and additional mechanisms influencing cHAB development and...

Acid-Sensitive Lakes Nine hundred and thirty-three lakes located in Saskatchewan, Alberta and the Northwest Territories were sampled to establish current acidification status. Of the 933 lakes, 244 (or 26%) are considered acid sensitive, almost always because of naturally low calcium and...

Sediment quality data for 20 lakes across Canada. Parameters include total mercury, methylmercury, sulfate, inorganic and organic carbon, nitrogen, and total recoverable metals. Bottom sediment samples were collected from one to three locations on each lake, following nationally standardized...

Annual freshwater quality monitoring data for 20 lakes across Canada. Parameters include total mercury, methylmercury, pH, alkalinity, specific conductance, colour, chlorophyll, nutrients, ions, dissolved inorganic and organic carbon, and total metals. In most years surface samples were collected...

Annual fish monitoring data for 20 lakes across Canada. Collection season was standardized to provide temporal comparability within each lake. In most lakes, fishing occurred in the fall. Predator fish were limited to trout, pike or walleye, to facilitate spatial comparisons. Ten to twenty top...

Environmental quality data from water, fish and sediments in 20 lakes across Canada. Measurements include mercury, methylmercury, physical-chemical parameters such as pH and alkalinity, stable isotopes, fish biological data, nutrients, ions, and metals. The data collection includes sites with a...
