This product provides runoff data with each contour line corresponding to an average amount of annual runoff (in millimeters). Runoff data were derived from discharge values from hydrometric stations with natural flows. Not all years are included for every region of the country due to data...

The "Starter Kits" of the Canadian Geospatial Data Infrastructure (CGDI) are curated bundles of geospatial data delivered as a service. These kits are the result of a user needs assessment commissioned by Natural Resources Canada (NRCan), with a primary focus on addressing the specific...

This study is focused on measuring lead in environmental matrices (surface water, sediment and tissues of recreational fish species) at locations known for high levels of recreational fishing activities (i.e. locations with high uses of lead in fishing sinkers and jigs) to determine the fate and...

This national map of flood susceptibility or flood prone areas is based on patterns of historic flood events as predicted by an ensemble machine learning model. The recommended use is national, provincial or regional scale and can be used as a guide for identifying areas for further...

Data represents surface water occurrence frequency (percentage), which describes the frequency for each grid appeared as water in the 30 years time period of 1991 to 2020. The data covers Canada’s entire landmass including all transboundary watersheds, and is at 30-meter spatial resolution. The...

The North America Surface Water Values point dataset contains the current water level and stream flow values as recorded by Canadian and USA hydrometric gauging station locations. Daily values are recorded as well as comparisons with historical measurements, including difference in values from...

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...

The National Hydro Network (NHN) focuses on providing a quality geometric description and a set of basic attributes describing Canada's inland surface waters. It provides geospatial digital data compliant with the NHN Standard such as lakes, reservoirs, watercourses (rivers and streams), canals,...

Long-term freshwater quality monitoring data for one site in the North Shore - Gaspé basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC)...

Long-term freshwater quality monitoring data for sites in the Maritime Coastal basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC) and...
