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 “Sub-sub-basins of the AAFC Watersheds Project – 2013” dataset is a geospatial data layer containing polygon features representing the Standard Drainage Area Classification (SDAC) 2003 defined sub-sub-drainage areas of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project.

Canada has eleven major drainage areas which are divided into 164 sub-drainage areas; the 164 sub-drainage areas are then further divided into 978 sub-sub-drainage areas. All drainage areas, sub-drainage areas and sub-sub-drainage areas are named and have an identifying ‘number’. Sub-sub-drainage areas have ‘numbers’ that share a common ‘fourcharacter’ designation. For example, the 05AB sub-sub-basin contains amongst others, station 05AB006, while the 05AC sub-sub-basin contains station 05AC007 (and others).

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 sub-subbasins are provided for hydrologic analyses and for creating maps for watershed management or other types of project.
