The Havasupai have settled in the region for over a millennium. During the late 19th century, increasing encroachments by cattle farmers and mining operations sanctioned by the United States federal government led to the displacement of the Havasupai from the high plateau of the Grand Canyon. As a result, the Havasupai were gradually confined to the floor of the Havasu Canyon, where they traditionally farmed the land nourished by silt deposited by the
Colorado River. In 1880, the federal government formally established the Havasupai Reservation within the canyon. In 1910, there was a flood of Supai which affected the town. In the 1960s, Martin Goodfriend, a tourist, began to advocate for the Supai people, and a columnist of the
Arizona Republic, Don Dedera, wrote articles about Goodfriend's findings. Dedera stated that Goodfriend countered a view that Supai was a kind of "
Shangri-la". 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 (subsequent to the main flooding event) 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. In July 2018, flash flooding forced the helicopter evacuation of 200 visitors. All tourism was suspended from March 2020 until February 2023 due to the
COVID-19 pandemic. ==Geography and climate==
