Tourism is a large portion of the economy of the reservation. The tribe runs its own tourism office, as well as a café, lodge, and general store. Individual members of the tribe also have small businesses, leading tour groups and packing supplies in and out of the canyon. In 2008, a dam burst upstream, causing a torrent to sweep through the canyon, resulting in significant damage to the natural resources as well as man-made structures. The tourism industry was devastated. The tribe received a one million dollar grant from the San Manuel Band of Mission Indians to assist in the economic recovery of the reservation.
