Gila River Indian Agency (Arizona)

History
The Gila River Agency existed for only two years -- 1864-1865 -- under that name. Its forerunner was the Pima, Papago, and Maricopa Agency and its successor was the Pima Agency. The earliest known records for the Pima Agency begin in 1888.

Records
No known records of the Gila River Agency have survived. Later records of the same locality and jurisdiction are part of the Pima Agency records.

The 1900 federal census included population schedules for the Gila River Reservation. The census includes the non-Indian employees of the Pima Agency, as well as many pages of Indian Population Schedules for the native population of the Reservation. They are recorded as District 79, Gila River Reservation in Maricopa County, Arizona and in District 79, Gila River Indian Reservation, in Pinal County, Arizona.
