The Cimarron River, flowing entirely in New Mexico, was also known as La Flecha or Semarone. Its headwaters are Moreno, Sixmile, and Cieneguilla creeks in the Sangre de Cristo Mountains Moreno Valley, which feed into Eagle Nest Dam. From the dam, it runs for 60 miles to below the city of Springer, New Mexico in the Taylor Springs area, where it flows into the Canadian River, the southwestern-most major tributary flowing into the Mississippi River via the Arkansas River sub-basin.
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.
The first dozen miles of the Cimarron River (from Eagle Nest Lake to Ute Park, New Mexico) are known for fine trout fishing. Stocked trout include rainbow and brown. The river is maintained by the New Mexico Department of Game and Fish at a trout density of approximately 3,000 fish per mile, although water flow can vary between 2 and 50 cubic feet per second.
