Notice

Note that the drainage basin polygons are a prerelease dataset that will continue to be updated as new polygons are added.

Users should be aware that drainage areas derived from these polygons may differ from the official hydrometric station drainage areas published by WSC. The official hydrometric station drainage areas will be updated after the polygons have undergone a final review.

For more information, please see the documentation.
