Arkansas River of Colorado, Kansas, Oklahoma Territory, Indian Territory, and Arkansas; one of the main western branches of Mississippi River, which it joins on the east boundary of Arkansas. The river beads in Tennessee Bass in central Colorado at an altitude of 10,000 feet above the sea; it flows first south in a mountain valley, and then east through a succession of canyons, passing out of the mountains just west of Canyon. Its course is east across the plains through eastern Colorado and Kansas, changing to southeast shortly before entering Oklahoma Territory, and so continuing through that Territory, Indian Territory, and Arkansas. Although its total length is 1,497 miles, with a drainage area of 185,671 square miles, it carries little water between Little Rock, Arkansas, and the western boundary of Kansas, except during times of flood, owing to the fact that the larger part of its drainage basin is within the arid region. Indeed in southern Kansas the stream bed is frequently dry in the late summer.
