The Arkansas River, which is a tributary of the Mississippi, is markedly down this year from past years. It's not uncommon for an August drought but this summer has been much drier than previous years. Side note: the mouth of the Arkansas River as it flows into the Mississippi is about 10 miles from where I lived in Cleveland, Mississippi. For anyone who has ever visited either the Arkansas or Mississippi Delta regions, you haven't seen much. Flat, rich earth, and poor.
