| Abstract |
The Watershed Project is a long-term Prairie Farm Rehabilitation Administration (PFRA) undertaking that has entailed the creation and maintenance of a drainage area database (based on hydrometric gauging stations) for the Canadian Prairies. This database has evolved considerably since its inception in the early 1970s. Currently, it consists of hydrometric gauging stations and watershed boundaries, tabulated gross and effective drainage areas, and digital products generated for use in hydrological mapping and analysis. The spatial extent of the database covers all of Alberta, Saskatchewan and Manitoba, and portions of adjacent jurisdictions (British Columbia, the Northwest Territories, Nunavut, Ontario, and the United States) into which Prairie watersheds extend.
The majority of gauging stations in this database are federal stations established by Water Survey of Canada (Environment Canada). This database also includes a relatively small number of provincial, American and “fictitious” gauging stations. The locations of these gauging stations were determined from Dominion Land Survey descriptions or from published latitude/longitude coordinates.
The GIS database is the authoritative source for the gross and effective drainage areas in the Prairie Provinces. It is composed of more than a dozen derivative output products that are available over the internet at http://www.agr.gc.ca/pfra/gis/gwshed_e.htm. |
