Doc Thompson's Tip of the Week

Flows out of Eagle Nest Lake are around 13 cfs with fairly clear water conditions. Current conditions can make for some fun dry fly fishing. Fish are a little skittish with clear water. We've been getting some rains recently so might see some slightly off color water conditions.

Description: About Cimarron River

The Cimarron River is located in Northern New Mexico and flows east from Eagle Nest, NM, through the Cimarron Canyon State Park and continues eastward to Cimarron, NM. There is 8-10 miles of public access in the Cimarron Canyon State Park. Three miles of private water can be accessed through Orvis Endorsed Guide, Doc Thompson. The Cimarron River is technically a small tailwater that fishes and looks more like a mountain freestone stream. The water features include riffles, pockets, bend pools, undercut banks, beaver ponds, drop-offs, runs and everything in between. These water characteristics, along with a dense aquatic insect population, make the Cimarron one of the best wild brown trout fisheries in the Southwest. New Mexico Game and Fish does stock rainbows throughout the Cimarron. The best time to fish the Cimarron is from May through mid October. Key hatches include Golden Stoneflies, PMDs, Tricos, Caddis, BWOs, Midges and Terrestrials. The Cimarron Canyon State Park has three maintained campgrounds with tent and RV sites. The small communities of Eagle Nest and Cimarron are the closest towns with basic amenities of restaurants, places to stay, gas stations, groceries and fishing licenses. The larger towns of Taos, Red River and Angel Fire offer more amenities but with a little longer drive.
