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...

This study set out to provide an up-to-date portrait of the per- and polyfluoroalkyl substances (PFAS) contamination status in a freshwater food web from the St. Lawrence River (QC, Canada). Water, sediments, aquatic vegetation, invertebrates, and some fish species were targeted for analysis. All...

Water level and discharge data are available from Water Survey of Canada’s Hydrometric Network. The Water Survey of Canada (WSC) is the national authority responsible for the collection, interpretation and dissemination of standardized water resource data and information in Canada. In...

Monitoring activities have collected bulk suspended sediment samples using continuous flow centrifuges and Phillips Tube samplers in the Lower Athabasca River and tributaries respectively. Further, in the absence of pre-development monitoring for this region, high fidelity dated lake sediment...

Long-term freshwater quality data from federal and federal-provincial sampling sites throughout Canada's aquatic ecosystems are included in this dataset. Measurements regularly include physical-chemical parameters such as temperature, pH, alkalinity, major ions, nutrients and metals. Collection...

Water quality and ecosystem health data are collected in the nearshore zone of the Great Lakes to address the problem of nuisance benthic algae. Monitoring data include physical and chemical water quality data as well as biological data, primarily from Cladophora and dreissenid mussels on the...

Water temperature data were collected by Environment and Climate Change Canada at selected locations in Lake Winnipeg.Thermograph moorings were deployed in the north basin at station 505 and 506, in the south basin at station 500, in the Lake Winnipeg Narrows at station 502, northwest of Berens...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada’s performance on key environmental sustainability issues. The data collection contains datasets that track water quality within Canada. The Water quality in Canadian rivers indicators...

This site provides public access to real-time hydrometric data collected at over 1800 locations and access to historical data collected at over 7600 stations (active and discontinued) in Canada. Hydrometric data are collected and compiled by Water Survey of Canada’s eight regional offices and...

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...

This dataset is part of the International Atomic Energy Agency (IAEA) Global Network of Isotopes in Precipitation (GNIP) project and contains the total monthly precipitation quantity in millimeters collected on the roof of the National Hydrology Research Centre in Saskatoon, SK and its stable...

Water quality and ecosystem health data used to conduct a cumulative effects assessment of Lake Ontario, Niagara River and St. Lawrence 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...

The Government of Canada is committed to the long-term sustainability of Canada's lakes and waterways to ensure that there is clean water for all Canadians, both for this, and future, generations. To this end, on August 2nd, 2012, Prime Minister Stephen Harper announced the launch of Phase II of...
