Diamond Creek (Hualapai: Gwada) is an intermittent stream that flows through the Hualapai tribal reservation generally north from Peach Springs, Arizona to the Colorado River.
Diamond Creek Road Diamond Creek Road is graded in the river canyon adjacent to, and in some cases, within the streambed of Diamond Creek. Diamond Creek Road provides the only vehicular access to the Colorado River between Lees Ferry, upriver and Pierce Ferry, downriver.Guide to the Colorado River in the Grand Canyon, Second Edition, Tom Martin and Duwain Whitis. This access makes Diamond Creek a popular location for whitewater rafting trips to take out from trips through the Grand Canyon. Rafting trips also launch from the same location and proceed downriver to Lake Mead. The Hualapai tribal government charges a fee for all vehicles and people traversing the road.Noncommercial River Trip Regulations, National Park Service; retrieved October 26, 2009.
Flash flooding During periods of heavy rain Diamond Creek is prone to flash flooding. Flash floods have historically damaged or destroyed the Diamond Creek Road forcing closure and, in one instance, washing vehicles into the Colorado River.Canyon by Michael P. Ghiglieri, University of Arizona Press, 1992, page 263
