Cimarron River (Canadian River)
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 Dam 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. The river begins 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 region is also home to the well known Philmont Scout Ranch.
Irrigation
The Cimarron River is primarily used to convey runoff water from the Moreno Valley, to local farmers and ranchers downstream who have water rights form Eagle Nest Lake. There are several diversion points along the river in which water is moved into canals and ditches. Some irrigation water travels more than 50 miles downstream to locations where it is to be used.
Fishing
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 cfs. Fishing season is busiest during the summer months.
