Lake Winnipeg usually experiences ice cover during December to May (South Basin)/ June (North Basin). This dataset are water quality data collected in the South Basin of Lake Winnipeg during the winter of 2024, for the Freshwater Lake Winnipeg project. The bottom part (10cm) of ice-core samples...

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...

What? Lake fish health is being monitored in five lakes throughout Cape Breton Highlands National Park (Freshwater Lake, Warren Lake, Broad Cove Mountain Lake, Branch Pond, and Benjie’s Lake). Data collected is used to determine species presence, CPUE (catch per unit effort), and body condition....

The effects of climate warming, eutrophication, air pollutant inputs and forestry activity that occurred before La Mauricie National Park was created influenced and continue to influence today water quality in the park. These stress factors threaten the natural evolution of aquatic ecosystems....

This dataset shows the locations of westslope cutthroat trout of non-stocked pure strain populations with average DNA purity ≥ 0.99%. This species is listed as threatened under the Species at Risk Act.

This measure monitors the trophic state (primary productivity) of six selected lakes, and four selected streams, in order to collect baseline data on processes fundamental to ecological structure and to detect any changes due to ecological stressors.

Historical water quality data measured on a continuous basis at over 23 locations across Canada is included in this dataset. Most locations include hourly temperature, dissolved oxygen, pH, specific conductance and turbidity. Data are collected by Environment and Climate Change Canada (ECCC) and...

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...

National Water Monitoring Program for Pesticides (NWMPP) water quality data are presented for a network of freshwater sites across Canada. A two-year pilot program is being conducted in partnership between Health Canada (HC), Environment and Climate Change Canada (ECCC), and Agriculture and...

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...
