Les données de monitoring de la qualité de l'eau pour trois sites dans le bassin des rivières Nelson et de la basse Saskatchewan pour les 15 dernières années ou plus pour les éléments nutritifs, les métaux, les ions majeurs et d'autre variables physico-chimiques sont incluses dans cet ensemble de données. Le monitoring est mené par Environnement et Changement climatique Canada (ECCC) afin d'évaluer l'état de la qualité de l'eau et les tendances à long terme, de détecter les problèmes émergents, d'établir les recommandations pour la qualité de l'eau et de suivre l'efficacité des mesures correctrices et des décisions réglementaires. L'information recueillie sert à l'initiative sur le bassin du Lac Winnipeg et supporte les activités de la Régie des eaux des provinces des prairies (REPP).

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 includes data from active sites, as well as historical sites that have a period of record suitable for trend analysis. Sampling frequencies vary according to monitoring objectives. The number of sites in the network varies slightly from year-to-year, as sites are adjusted according to a risk-based adaptive management framework. The Great Lakes are sampled on a rotation basis and not all sites are sampled every year. Data are collected to meet federal commitments related to transboundary watersheds (rivers and lakes crossing international, inter-provincial and territorial borders) or under authorities such as the Department of the Environment Act, the Canada Water Act, the Canadian Environmental Protection Act, 1999, the Federal Sustainable Development Strategy, or to meet Canada's commitments under the 1969 Master Agreement on Apportionment.
