About Cimarron River
The Cimarron River in Colorado, a freestone river flowing from the San Juan Mountains, offers a diverse fly fishing experience with easily accessible public water. Anglers can expect to encounter plentiful rainbow and cutthroat trout, with opportunities for larger specimens in the upper forks and tailwater sections near Silver Jack Reservoir. Key insect activity includes Midges, Blue Wing Olives (BWO), Pale Morning Duns (PMD), Caddis, Yellow Sally Stoneflies, and Terrestrials, providing consistent opportunities throughout the fishing season. The river features a mix of shallow riffles and deep pools, with access points reachable from Highway 50, though awareness of private property is advised. Waders are recommended for navigating the varied water types.
