End of the line. Approximately a quarter mile from the parking area, another dam ends the water in the Salt River channel. Water is instead diverted into 4 canals that serve much of the Phoenix Metro Area. The Granite Reef parking area is rather small, and as a result trailers are not permitted to park in the parking area. As with other Lower Salt RAPs, Tonto passes are required, pit toilets are available, as are some BBQ grills and picknick areas.
