This layer was converted to a shapefile from a Esri File Geodatabase from Open Canada Portal, https://open.canada.ca/data/en/dataset/c20d97e7-60d8-4df8-8611-4d499a796493 .

The "Hydrometric Gauging Stations of the AAFC Watersheds Project - 2013" dataset is a geospatial data layer containing point features representing the hydrometric gauging stations of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. The gauging stations are sourced from Environment Canada, the United States and Canadian provinces. Additional virtual stations have been generated to address hydrometric  structural issues, like river confluences or lake inlets. Attribute information includes station identification, location, and associated catchments/basins.

Originally, the Project was to generate a drainage area database intended to provide the basis for updating regional flood and runoff studies. The database was available to all potential users. Over the years many geospatial data layers have evolved. These gauging stations and their associated information were used in the Project to define drainage areas. They are available for hydrologic analyses, the generation of hydrologic datasets, and for creating maps for watershed management or other types of project.
