The uppermost lock and dam on the Upper Mississippi River is the Upper St. Anthony Falls Lock and Dam in Minneapolis. Above the dam, the river's elevation is 799 feet (244 m). Below the dam, the river's elevation is 750 feet (230 m). This 49-foot (15 m) drop is the largest of all the Mississippi River locks and dams.
It flows west to east starting in Colorado and dumping into the Mississippi River. Its length of 1,469 miles (2,364 km) allows it to flow through Colorado, Kansas, Oklahoma, and Arkansas. It is the sixth-longest river in the US, the second-longest tributary to the Mississippi River System, and the 45th longest river in the world. [11]
Stream gradient may change along the stream course. An average gradient can be defined, known as the relief ratio, which gives the average drop in elevation per unit length of river. [4] The calculation is the difference in elevation between the river's source and the river terminus (confluence or mouth) divided by the total length of the river ...

For example, due to 18 cutoffs created between 1766 and 1885, the length of the Mississippi River from Cairo, Illinois, to New Orleans, Louisiana, was reduced by 351 kilometres (218 miles). [10] These points make it difficult, if not impossible, to get an accurate measurement of the length of a river.
There is a feasibility study to dredge this portion of the river to 50 feet to allow New Panamax ship depths. [8] Downbound barge rates In late 2022, low water levels in the Lower Mississippi River caused two backups that held up over 100 tow boats with 2,000 barge units, causing barge rates to soar [9] [10] Mississippi River levels at Memphis ...
