Historical Watershed Boundary Maps

Abstract

The Historical Watershed Boundary Maps consists of the watersheds printed colour maps within Alberta that were delineated as part of the Phase 3 Forest Inventory program. The maps have been scanned in black and white as well as colour and sorted by the National Topographic System (NTS) 1:50 000 and 1:250 000 blocks. The series is now available as a fee free download in Adobe PDF and Tif formats under the Open Government Licence – Alberta.

The Historical Watershed Boundary Maps were originally created to assist in management of Alberta's forests. Through the use of the maps and the accompanying data, forest resource planners in the government and the private sector were able to make sound resource management decisions using drainage basins as a base.

These maps are not available as geo-referenced rectified images or GIS-ready data.
