Website change notification: To simplify finding documents from the Interior Region 7 – Upper Colorado Basin, items currently housed in the Environmental Document web pages will be moved to a more inclusive Document Library.
The current pages will remain active as the transition to the new organization and navigation take place. Eventually the old navigation button and pages will be decommissioned, therefore if you have these pages bookmarked, please be sure to update them to reflect the new Document Library address.
