Cimarron River (Canadian River watershed)

The Cimarron River, flowing entirely in New Mexico, was originally known as the "Le Flecha". It runs for 60 miles (97 km) from Eagle Nest Lake to below the city of Springer, New Mexico and is a tributary of the Canadian River, the southwesternmost major tributary flowing into the Mississippi River via the Arkansas River sub-basin. Near Philmont Scout Ranch, the first dozen miles of the Cimarron River (above Cimarron, New Mexico) are known for fine trout fishing.
