The town of Gila Bend is situated near an ancient Hohokam village. Father Eusebio Francisco Kino was the first European to visit in 1699 on his first journey of exploration to the Colorado River. The Hohokam site along fertile banks of the Gila River had been abandoned and other tribes, lived in the vicinity. 132 Pima people lived in a rancheria called Oyadaibuc or as Kino named it San Felipe y Santiago del Oyadaibuc, near the modern town, and other Pima lived in three rancherias up river to the north mixed with the Cocomaricopa or Opa. During one of his three visits to Gila Bend, Kino counted 960 Opas living in their own rancherias down river to the west of Oyadaibuc as far as a few miles beyond Agua Caliente.: The Opa and Pima used the flood waters of the river to irrigate their crops. Oyadaibuc was also visited by Juan Bautista de Anza, commander of the Presidio at Tubac and founder of the city of San Francisco, and by Father Francisco Tomas Garces in 1774. As late as the 1820s Maricopa were living at Gila Bend. After the 1820s, the Maricopa, under relentless pressure from the Yuma and other tribes, and population loss from epidemics, had been compelled to leave the Gila Bend and join the Pima in the Middle Gila region. By the time of the California Gold Rush the Maricopa villages, were all located east of the Sierra Estrella, on the Gila River, below the Pima Villages.:
