Water Quantity Monitoring

A hydrometric technologist monitors water levels on a river.Information about water quantity is required by a wide audience, including research scientists, policy-makers, design engineers and the general public. Water level, flow and sediment data are used by decision makers to resolve issues related to sustainable use, infrastructure planning and water apportionment. Hydrological models use the data to improve the forecasting of floods and water supplies, and to predict the impacts of changes on flow regimes to human and aquatic health and economic activity.

Environment Canada is the federal agency responsible for the collection, interpretation, and dissemination of standardized water quantity data and information in Canada. EC has maintained the National Hydrometric Program through cost-shared agreements with the provinces and territories since the mid-1970s. Established in 1908, EC's Water Survey of Canada is the designated branch responsible for water resource monitoring in support of interjurisdictional agreements and treaties.
