The Cimarron River, flowing entirely in New Mexico, United States, was also known as La Flecha^[2] or Semarone. Its headwaters are Moreno, Sixmile, and Cieneguilla creeks in the Sangre de Cristo Mountains, which feed into Eagle Nest Dam. From the dam, it runs for 60 miles (97 km) to below the city of Springer, New Mexico, in the Taylor Springs area, where it flows into the Canadian River,^[1][3] the southwesternmost major tributary flowing into the Mississippi River via the Arkansas River sub-basin.^[3][4]

This river flows within a mountainous canyon that is part of Cimarron Canyon State Park in the lower Sangre de Cristo Mountains and runs down into eastern plains of New Mexico.^[5] This headwaters region is also home to the Philmont Scout Ranch.^[6]
