This is a List of tributaries of the Gila River, the final river drainage of the Colorado River, and covers the entire width of southern Arizona. The headwaters of the Gila River begin in the Gila National Forest of New Mexico. The northern branch tributary to the Gila River in the Gila National Forest, is the San Francisco River. The map highlights the Gila River extending eastward across southern Arizona to the southwestern corner of Arizona and its input into the Colorado River, from its origins about 400 miles east in the southwestern corner of the state of New Mexico. The highlighted river north and adjacent is the Salt River which has the Verde River connected just prior to its drainage into the Gila River. The Verde and Salt rivers effectively drain the western and central portion of the Mogollon Rim, NW to SE across the state, and the White Mountain region of the Mogollon Rim, in east-central, and east Arizona. The Verde River drainage into the Salt River, at its very northwestern drainages, east of Kingman, Arizona, even drains the South Rim, of the Grand Canyon. Thus, the ''Gila River watershed'', may cover more than sixty (60) percent of the state. ==The 3-north-south drainages + Salt-Verde Watershed== From west–to–east the Hassayampa River's final destination is the dry desert, and groundwater. The second drainage, the Agua Fria River enters the Gila in western Phoenix, but not as a flowing river. The Agua Fria puts most of its winter drainage, or snowmelt/rain floodwaters into Lake Pleasant Regional Park. The largest of the ''three'' north/south rivers, the Verde River(plus the East Verde), goes through Horseshoe Reservoir and Bartlett Reservoir before joining the Salt River. (The Salt River enters the Gila, 40 miles downstream, through central Phoenix, and five miles before the Agua Fria River tributary. The Hassayampa River is 35 miles farther downstream, and just prior to the tributary of Centennial Wash.) The Verde River drainage extends north and northwest of the Agua Fria River, and Hassayampa River drainages, and continues to the South Rim of the Grand Canyon. The combined: ''Salt River–Verde River Drainage'' would be the major, (and central), component of the Mogollon Rim drainages of central Arizona. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of tributaries of the Gila River」の詳細全文を読む スポンサード リンク
