AI-generated Key Takeaways
-
The USGS Watershed Boundary Dataset (WBD) provides a comprehensive, nationally consistent representation of hydrologic units at multiple scales (HUC02-HUC12).
-
The WBD delineates surface water drainage areas, defining the areal extent of water flow to a specific point.
-
Datasets are available for regions, subregions, basins, subbasins, watersheds, and subwatersheds, allowing for analysis at various levels of detail.
-
The WBD is valuable for hydrological modeling, water resource management, and environmental analysis.
-
Coastal and lake front areas may have unique drainage patterns that deviate from the standard point-based definition.
