Is the Colorado River the only navigable river in Arizona?
The Arizona Navigable Stream Adjudication Commission has been charged with determining the navigability at the time of statehood of all of the other rivers, streams and washes in the state. In 2006, they completed their determinations and declared all were non-navigable. The decisions on the Upper and Lower Salt, Verde, San Pedro and Santa Cruz rivers have been challenged in various appeals courts and are still under review.
