Salt River

Where the Salt River comes from

Nearly 200 miles from the White Mountains of eastern Arizona, through the Salt River Canyon and four reservoirs, to the Gila below Phoenix.

Headwaters

The White Mountains

The Salt begins where the White and Black rivers meet, in the valley between the Mogollon Rim and the Natanes Plateau. Both are fed by springs and creeks in the White Mountains of eastern Arizona and by snowmelt from Mount Baldy, about 11,400 feet.1,2,3

Between two reservations

The Black River, and then the Salt, form the boundary between the Fort Apache Indian Reservation (White Mountain Apache) to the north and the San Carlos Apache Reservation to the south.1,2

Dams, then the desert

Below the Salt River Canyon the river fills Roosevelt, Apache, Canyon and Saguaro lakes. Near Fountain Hills the Verde joins it, and at Granite Reef Diversion Dam most of the water goes into the Valley's canals; through Tempe and Phoenix the bed is usually dry until the Salt meets the Gila.1,4

The river, top to bottom

  1. White MountainsThe North Fork of the White River and the Black River gather snowmelt from Mount Baldy.
  2. White and Black rivers meetThe Salt begins; Carrizo and Cibecue creeks come in from the Mogollon Rim.
  3. Salt River CanyonUS-60 crosses at the bottom; Canyon and Cherry creeks join below.
  4. Roosevelt LakeTonto Creek comes in from the Mogollon Rim, Pinal Creek from Globe.

Why it matters for floods

The Salt's big floods come in winter, when storms rain on snow in the White Mountains and along the Mogollon Rim and fill the reservoirs; when the dams have to release, water runs through Phoenix's normally dry riverbed, as in 1978 and 1980. Summer thunderstorms flash the side canyons below the dams.5,1 The live map watches the gauges along the way.
