(CNN) — Heavy overnight rains flooded a stretch of the Colorado River through the Grand Canyon, forcing the evacuation of hundreds of tourists and residents, officials said Sunday.

The rains caused a breach at the earthen Redland Dam early Sunday, sending a rush of water into the Supai village, within the Havasupai Indian Reservation, said Gerry Blair, spokesman for the Coconino County sheriff’s department.

He said helicopters were evacuating more than 200 campers, paddlers and other tourists, and another 200 residents of the Supai area.
