Consider "Hydrology Units HUC8 and FDA" to supercede/supplement HUC8 availability for tools with a trans-boundary spatial domain.
This dataset was made in the 2015 range by the Northwest Boreal LCC (one of the original IEM project collaborators/funders) and should provide HUC8-scale watershed options for the NCR spatial domain when supplemented with HUC8s outside of the Northwest Boreal region.
Brown in the screenshot above is Canadian FDAs, Yellow is US HUC8s, and green is the rectified transboundary dataset provided by UAlberta.
