Contents 1 Recent history 2 Geography and climate 2.1 Climate 3 Demographics 4 Access 5 Services 6 References 7 External links Recent history Tourists and some residents were evacuated from Supai and surrounding area on August 17 and 18, 2008, due to flooding of Havasu Creek complicated by the failure of the earthen Redlands Dam after a night of heavy rainfall. Evacuees were taken to Peach Springs, Arizona. More heavy rains were expected and a flash flood warning was put into effect, necessitating the evacuation, according to the National Park Service. The floods were significant enough to attract coverage from international media. Damage to the trails, bridges, and campground was severe enough for Havasupai to close visitor access to the village, campground, and falls until the spring of 2009. Further flooding in 2010 resulted in damage to repairs made previously and closures effective until May 2011.
