Abstract

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 “Major Basins of the AAFC Watersheds Project - 2013” dataset is a geospatial data layer containing polygon features representing the 23 major basins of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project.

The Project is subdivided by ‘incremental gross drainage areas’ associated to individual hydrometric gauging stations. The maximum area that could contribute runoff to each gauging station, less that of its upstream neighbour(s) is called an ‘incremental gross drainage area’. Conceptually, the major basins are collections of the “incremental gross drainage areas” associated with particular major river or lake reach (for example, reaches of the Saskatchewan or Athabasca River). In practice, each major basin consists of the collection of incremental gross drainage areas, whose gauging stations’ numbers have collections of the same three first characters. For example, the Assiniboine River major basin contains the incremental gross drainage areas whose gauging station numbers start with 05J, 05M, or 05N.

Purpose

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. The prairie major basins are provided for hydrologic analyses, the generation of hydrologic datasets, and for creating maps for watershed management or other types of project.
