Location of GWFO instrumented field sites and the major river basins they are situated within across Canada.

GWFO operates a national network of water observation sites that collect continuous and intermittent measurements of hydrometeorological conditions, water quantity and quality, ecological and biological indicators, contaminants, and other water-related variables. Some are long-term observatories with records spanning decades, while newer sites provide targeted observations in remote, data-sparse, and poorly understood regions, together delivering early warning of emerging water stresses and enabling detection of hydrological and water quality change. These sites and their data are available to scientific and operational users through established access and data-sharing policies, supporting improved understanding and decision-making in the face of climate change and other human pressures.
