Knowledge of the location of Earth’s surface water in time and space is critical to inform policy decisions on environment, wildlife, and human security. Dynamic surface water maps generally represent water occurrence, also referred to as inundation frequency, depicting the percentage of valid...

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...

A station is a site on a river or lake where water quantity (water level and flow) are collected and recorded.

The daily mean is the average of all unit values for a given day.

The Coastal Ice-Ocean Predicton System (CIOPS) provides a 48 hour ocean and ice forecast over different domains (East, West, Salish Sea) four times a day at 1/36° resolution. A pseudo-analysis component is forced at the ocean boundaries by the Regional Ice-Ocean Prediction System (RIOPS)...

The annual maximum and minimum instantaneous data are the maximum and minimum instantaneous values for a given year.

The annual maximum and minimum daily data are the maximum and minimum daily mean values for a given year.

The monthly mean is the average of daily mean values for a given month.

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The phosphorus loading to lake Erie indicator reports on the total phosphorus loads flowing directly into Lake Erie or from...

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...

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...

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...

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...

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...
