AAFC Watershed Project - 2013 The Agriculture and Agri-Food Canada’s (AAFC) Watersheds Project level series supplies a number of watershed and watershed related datasets for the Prairie Provinces. The levels are greater or smaller assemblages of hydrometric areas, or the components defining them. The Project is organized by hydrometric gauging stations which are sourced from Environment Canada, the United States, and Canadian provinces. Additional stations were generated to address structural issues, like river confluences or lake inlets. Collectively, they are referred to as the gauging stations, or simply, the stations. The drainage area that each station monitors, between itself and one or more of its upstream neighbours, is called an ‘incremental gross drainage area’. The incremental gross drainage areas are collected into larger or smaller groupings based on size or defined interest to generate the various ‘levels ’of the series. They include: Basins of varying size: 1. Major drainage systems (3): Arctic Ocean, Hudson Bay and Gulf of Mexico; 2. Major basins (23): associated with river or lake reaches; 3. Project sub-basins (47): created specifically for the project; 4. Sub-basins (51): based on specific Environment Canada hydrometric gauging station locations; 5. Sub-sub-basins (311): based on specific Environment Canada hydrometric gauging station locations); Incremental drainage areas: 6. Incremental gross drainage areas: one per gauging station. The incremental gross drainage areas are further subdivided into portions that either contribute or do not contribute to drainage to an average runoff event. The portions that do contribute are called ‘effective drainage’ areas, while those that don’t are called ‘non-contributing’. These generate the following levels: 7. Incremental effective drainage areas; and 8. Incremental non-contributing areas. Total drainage areas: 9. Total gross drainage areas; 10. Total effective drainage areas; and 11. Total non-contributing areas; And when combined for the entire project, yields the: 12. Effective drainage area. The series also includes the components: 13. The gauging stations; 14. The collection of boundaries (lines) of the gross incremental drainage areas as well as the boundaries that separate contributing from non-contributing areas for an average runoff event; and 15. A network of downstream-directed lines that connect the gauging stations. All linework is derived from large scale topographic data. One additional non-spatial dataset, a table of tallied values by gauging station, is provided: 16. The Project Gauging Station Table. The Project area, designed for the Prairie Provinces, covers all of Alberta, Saskatchewan and Manitoba, and those portions of British Columbia, Northwest Territories, Nunavut, Ontario, and the United States that are required to complete the trans-border sections of the watersheds. Since 1975 the AAFC Watersheds Project has systematically collected and refined watershed boundaries for the Prairies. The result is the authoritative source for gross and effective drainage areas in the Prairie Provinces. The initial 1:50,000 analog delineations were moved to their digital form in 1994. Since then, the delineations have increased in accuracy and extent, and the series levels have increased to 16 in number. 2020-12-09 Agriculture and Agri-Food Canada Agri-Geomatics-Agrog@agr.gc.ca Nature and EnvironmentWatershedsHydrologyWaterDrainageInland watersWestern provinces Data Product Specification (English)PDF https://www.agr.gc.ca/atlas/supportdocument_documentdesupport/aafcWatersheds2013/en/ISO_19131_AAFC_Watersheds_Project_2013_Data_Product_Specification.pdf Data Product Specification (French)PDF https://www.agr.gc.ca/atlas/supportdocument_documentdesupport/aafcWatersheds2013/fr/Projet_des_bassins_hydrographiques_d_AAC_2013_Specifications_de_contenu_informationnel_ISO_19131.pdf Pre-packaged FGDB filesFGDB/GDB https://www.agr.gc.ca/atlas/data_donnees/hyd/aafcWatersheds2013/fgdb/ Pre-packaged GML filesGML https://www.agr.gc.ca/atlas/data_donnees/hyd/aafcWatersheds2013/gml/ AAFC Watershed Project - 2013 (AGOL) (English)ESRI REST https://www.arcgis.com/home/item.html?id=9c2e6ea87692432c8e66c4332704a17f AAFC Watershed Project - 2013 (AGOL) (French)ESRI REST https://www.arcgis.com/home/item.html?id=0898ad2a7629433ebe4e2feaed4f6a1d AAFC Watershed Project - 2013 (English)ESRI REST https://www5.agr.gc.ca/atlas/rest/services/mapservices/aafc_watershed_2013/MapServer AAFC Watershed Project - 2013 (English)WMS https://www5.agr.gc.ca/atlas/services/mapservices/aafc_watershed_2013/MapServer/WMSServer?request=GetCapabilities&service=WMS AAFC Watershed Project - 2013 (French)ESRI REST https://www5.agr.gc.ca/atlas/rest/services/servicesdecarte/aac_bassin_hydrographique_2013/MapServer AAFC Watershed Project - 2013 (French)WMS https://www5.agr.gc.ca/atlas/services/servicesdecarte/aac_bassin_hydrographique_2013/MapServer/WMSServer?request=GetCapabilities&service=WMS

AAFC Watershed Project - 2013

The Agriculture and Agri-Food Canada’s (AAFC) Watersheds Project level series supplies a number of watershed and watershed related datasets for the Prairie Provinces. The levels are greater or smaller assemblages of hydrometric areas, or the components defining them.

The Project is organized by hydrometric gauging stations which are sourced from Environment Canada, the United States, and Canadian provinces. Additional stations were generated to address structural issues, like river confluences or lake inlets. Collectively, they are referred to as the gauging stations, or simply, the stations.

The drainage area that each station monitors, between itself and one or more of its upstream neighbours, is called an ‘incremental gross drainage area’.

The incremental gross drainage areas are collected into larger or smaller groupings based on size or defined interest to generate the various ‘levels ’of the series. They include:

Basins of varying size:

  1. Major drainage systems (3): Arctic Ocean, Hudson Bay and Gulf of Mexico;

  2. Major basins (23): associated with river or lake reaches;

  3. Project sub-basins (47): created specifically for the project;

  4. Sub-basins (51): based on specific Environment Canada hydrometric gauging station locations;

  5. Sub-sub-basins (311): based on specific Environment Canada hydrometric gauging station locations);

Incremental drainage areas:

  1. Incremental gross drainage areas: one per gauging station.

The incremental gross drainage areas are further subdivided into portions that either contribute or do not contribute to drainage to an average runoff event. The portions that do contribute are called ‘effective drainage’ areas, while those that don’t are called ‘non-contributing’. These generate the following levels:

  1. Incremental effective drainage areas; and

  2. Incremental non-contributing areas.

Total drainage areas:

  1. Total gross drainage areas;

  2. Total effective drainage areas; and

  3. Total non-contributing areas;

And when combined for the entire project, yields the:

  1. Effective drainage area.

The series also includes the components:

  1. The gauging stations;

  2. The collection of boundaries (lines) of the gross incremental drainage areas as well as the boundaries that separate contributing from non-contributing areas for an average runoff event; and

  3. A network of downstream-directed lines that connect the gauging stations.

All linework is derived from large scale topographic data.

One additional non-spatial dataset, a table of tallied values by gauging station, is provided:
