What is the largest river flowing through Arkansas?

The Arkansas River is the largest river that flows entirely within the state of Arkansas, making it the most significant waterway in terms of both size and impact on the region. The Arkansas River originates in the Rocky Mountains of Colorado and flows southeast through several states, including Arkansas, before emptying into the Mississippi River. While the Mississippi River is larger overall and forms the state's eastern border, it does not flow through Arkansas in its entirety and thus is not classified as the largest river within the state itself.

The Arkansas River serves as a vital resource for the state, supporting agriculture, recreation, and ecosystems. It's also pivotal for navigation and local economies. Understanding the characteristics and significance of the Arkansas River helps to highlight its prominence compared to other rivers that might flow through Arkansas but are either smaller or do not cover as much area within the state.
