Which river is the longest river in Oklahoma?

The longest river in Oklahoma is the Arkansas River, which stretches approximately 1,469 miles in total length, passing through various states including Oklahoma. Within Oklahoma, the river plays a significant role in the state's geography and economy. It begins in the Rocky Mountains of Colorado and flows southeast into Oklahoma before continuing into Arkansas.

The Canadian River, while important and lengthy within Oklahoma, does not surpass the Arkansas River in total length. The Red River serves as a boundary between Oklahoma and Texas but is not the longest river within the state itself. The Grand River, which is a tributary of the Neosho River, is shorter compared to the aforementioned rivers.

Understanding the significance and geographical context of each river allows for a clearer distinction between their lengths and contributions to Oklahoman history and water systems.
