This dataset comprises a map of inland water bodies in Canada and neighboring regions, as described by Ghayourmanesh et al. (2024). The data are mapped using the Lambert Conformal Conic (LCC) geographic projection with a spatial resolution of 250 meters. The LCC projection is frequently used as a...

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 Canadian Hydrospatial Network (CHN) is an analysis-ready geospatial network of features that help enable the modelling of surface water flow in Canada. The six main layers and feature types are: flowlines, waterbodies, catchments, catchment aggregates, work units, and hydro nodes. Where...

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.

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,...

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...
