Description:

Abstract:

The Environment Canada Sub-basin product is the most detailed watershed product. There are 44 basins which cover (in Canada) Northern British Columbia, Alberta, Saskatchewan, Manitoba, and (in the United States) North Dakota, Montana, and Minnesota.

Purpose:

To supply the thematic layer of Environment Canada sub-basins of the PFRA Watershed Project for hydroligic analyses and mapping in watershed management across the Canadian prairies.

Attribute_Definition:

This 3-character attribute is based on the first 3 characters of Environment Canada's gauging station number. The number is designed to be hierarchical. Stations whose name share the first 3 characters, are meant to share a common "reach" in the drainage system. Note: Some gauges were labelled in a mistaken "reach". As a result, there are some gauging stations whose first 3 name characters which will not match their sub_ec code. As well, Provincial gauging stations with a 6 digit code ie (059-012) have been assigned to their proper 3 character sub_ec "reach" code.
