The goal of this workshop is to populate the new subset of Subbasins (US8-CAN4units) that constitute the boundary region along the Alaska-British Columbia border with seamless Watersheds (US 10-digit, WSC 6-digit codes) and Subwatersheds (US 12-digit, WSC 7- digit codes), standardized and interoperable with both Canadian and U.S. Federal, State and Provincial drainage area interpretations. All recommended delineations are based on standard topographic, hydrographic base layers and local data holdings. The structure of the workshop is interactive; IJC Task Force members prepare an ArcMap edit session and table in order to capture comments and suggested edits for each of these aggregations. Particular focus is placed on confluences and ridgeline placement.

Harmonization of the 10-digit, and all 12-digit within a shared 10-digit is the focus of the workshop. Proposed delineations will be posted for participant review one month prior to the workshop.
