Arkansas River: Basin Breakdown

Men working at Amity Dam, Arkansas River, 1909With its headwaters in the Rocky Mountains near Leadville, the Arkansas River stretches nearly 1,500 miles to the Mississippi River. Once serving in part as the border between Mexico and the United States, the river has played a significant role in the history of Colorado, from the discovery of gold to the development of irrigation. The Arkansas has witnessed floods and droughts, numerous legal battles have been waged internally and across state lines, and a major transmountain diversion now supplements native flows.
