Arizona Water Science Center Highlights
The video describes observations made by AzWSC scientists on the recent high-flow event that occurred around August 17th, in Havasu Canyon on the Havasupai Indian Reservation, northern Arizona. The Havasupai Indian Tribe lives in the remote Havasu Canyon, a tributary canyon to Grand Canyon National Park, and is only accessible by foot, horseback, or helicopter. The high-flow event caused massive erosion below the village of Supai, resulting in the creation of new water falls and the cessation of Navajo Falls. AzWSC scientists made assessments of the high-flow event on August 28th and 29th, and made an indirect measurement of the peak flow that passed through the village of Supai. A preliminary calculation of the peak flow is 6,000 cubic feet per second. (August 29, 2008 — narrated by Greg Fisk and Steve Wiele)
