The Arkansas River Basin originates in the Rocky Mountains and empties into the Lower Mississippi River, covering a total length of 1,469 miles. It is the second longest tributary of the Mississippi River and is highly valued for its recreational uses including swimming, boating, fishing and hunting. Navigation on the lower portion of the river is maintained by a series of 18 locks and dams, which also enhance recreation, produce hydroelectric power and provide flood control.
The Red River Basin forms most of the Texas-Oklahoma border before emptying into the Mississippi River in Louisiana. Much of the management of the river, according to the Red River Compact, is based on the appropriation of water to agriculture, municipalities, industry, hydroelectric power and recreational uses while balancing ecosystem health needs.

The Arkansas and Red River Basin also faces additional challenges in water stress associated with potential transfers of water resources outside of the basin. A substantial portion of the basin is west of the 100th meridian that marks a shift in precipitation, with wetter conditions to the east of the 100th meridian. The very poor result for lock delays, combined with the very poor infrastructure condition and maintenance, are especially troubling considering that these locks and dams are newer than many other sections of the system having been completed in the early 1970s.
