Historical Watershed Boundary Maps for Alberta Forest Inventory

Historical Watershed Boundary Maps consist of scanned color and black-and-white maps delineated for Alberta's Phase 3 Forest Inventory program. Approximately two-thirds of the series is currently available in PDF and TIFF formats, sorted by National Topographic System blocks within ZIP files. The Government of Alberta produced this series, which is not updated and contains a range of publication dates and scales.
