Stormwater ponds have been widely used to control increased volumes and rates of surface runoff resulting from urbanization. Stormwater ponds have also been designed to provide multiple other benefits; including protection of downstream waters, sediment and habitat (land/aquatic) quality,...

Water quality monitoring data collected in priority tributaries to provide nutrient concentration data to estimate nutrient loads to the waters of the Great Lakes. Data is collected to advance the science to understand and address the complex problem of recurrent toxic and nuisance algae in the...

Expanded Geographic Area (M9, M10, M11a, M12, BI1, RI1, SL1, SL2, QU1 [2013] and M9, M10, M11a, M12, BI1, BU1, BU2, RI1, SL1, SL2, QU1, MC2 [2011-March 2018]) Water quality chemistry data for 17 sites in the lower Athabasca River (LAR), the Peace and Slave rivers, and their tributaries, including...

Shallow groundwater and the interaction of these waters with surface water in the mineable area of the Athabasca oil sands region are being examined to assess the role and importance of groundwater in the regional river ecosystems. Groundwater quality chemistry data is available from 182 shallow...

The Turkey Lakes Watershed (TLW) Study was initiated in 1980 by Environment Canada, Natural Resources Canada and Fisheries and Oceans Canada to evaluate anthropogenic perturbation of Canadian Shield ecosystems. Originally, the Study focused on the aquatic and terrestrial effects of acid rain, but...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Water quality in Canadian rivers indicators provide a measure of the ability of river water across Canada to support...

This dataset, in part, is composed of aquatic benthic macroinvertebrate taxa lists generated as part of the Sequencing the River for Environmental Assessment and Monitoring (STREAM) project (see www.STREAM-DNA.com for more details). Benthic macroinvertebrate sampling was based upon existing...

Water quality and ecosystem health data collected using a risk-based monitoring approach to support the Great Lakes Water Quality Agreement are included in this dataset. By conducting regular, systematic measurements of the physical, chemical and biological conditions of the Great Lakes...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Water quality in Canadian rivers indicators provide a measure of the ability of river water across Canada to support...

We studied the community structure of crustacean zooplankton along the biogeographical zones of the St. Lawrence River (Québec, Canada), to evaluate how the riverscale hydrological network formed by water masses, and local-scale aquatic environment, influenced the distribution of zooplankton...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Reductions in phosphorus loads to Lake Winnipeg indicator shows the estimated extent to which projects funded by the Lake...

Stream sampling was conducted in the Whitemans Creek watershed in February 2012 to assess water quality during winter baseflow conditions. A total of 30 stream sites were sampled where streams in the watershed intersected roadways. In addition to conventional water quality parameters (e.g.,...

As part of a study to characterize the habitat of Canada’s only known population of Hine’s emerald dragonfly (HED), a species listed as endangered since 2011, groundwater was collected and analyzed from the eastern Minesing Wetlands near Barrie, Ontario. The water quality analyses included...

As part of the research activities of the St. Lawrence Action Plan (SLAP) and in collaboration with Parks Canada, a 5-year monitoring program was initiated to assess the effect of metal and element contamination to clams in the Tadoussac area. The sites of concern included marinas near...

The Fish Contaminants Monitoring Program (FCMP) was initiated in 1976. The objective is to collect a variety of biological samples in freshwater environments for the purpose of determining ecosystem contaminant levels. Environment and Climate Change Canada (ECCC) collects biological samples from...

This project examined the use of parasites of slimy sculpin (Cottus cognatus) as indicators of water quality in the Athabasca River. Specimens of C. cognatus were sampled from four tributaries to assess patterns of helminth parasite community structure in this fish and to study the composition...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. If unsafe bacterial levels are measured in water samples or if shoreline surveys identify pollution concerns, Environment and...

In 2022, the Watershed Hydrology and Ecosystems Research Division of Environment and Climate Change Canada (ECCC) uploaded a Lake Ice Database to the Government of Canada open data portal (https://data-donnees.ec.gc.ca/data/water/scientificknowledge/lake-ice-database/?lang=en). This companion...

Water quality and ecosystem health data used to conduct a cumulative effects assessment of Lake Huron and St. Marys River nearshore waters in support of the Great Lakes Water Quality Agreement are included in this dataset. Data related to nearshore stressors is integrated into an overall...

Weekly precipitation quantity has been measured at both at the primary meteorological site as well as at five other sites within the watershed. Daily precipitation quantity has been measured at the primary meteorological site until 2017. Weekly chemistry analysis of H+, major ions, nutrients and...
