There have been 3 versions to date:

Watershed Level Sq Miles /Acres
This Hierarchy and Naming/Numbering System is the California System – and does not correspond directly to the Federal System used in the WBD.
But it is currently the “best (only) available data.”
Review Procedure (FGDC Guidelines):
Nov2003National WDB Status
For local planning and mapping purposes, California plans to extend the watershed hierarchy down two more levels, to include Levels 7 and 8.
This will require additional funding and commitment to complete.
