This site provides a quick way to identify the 8, 10, and 12-digit Hydrologic Unit Code (HUC) for any point in Indiana. The 11 and 14-digit HUCs in the older system are also provided, for reference between the two systems.
Instructions: Click on any point. The map will zoom in, so that the point is unambiguous. Click a second time and the HUC numbers will be displayed, both in the new system (HUC 8, 10, 12) and the old system (HUC 11 and 14).
