Silver Jack Dam (National ID # CO01693) is a dam in Gunnison County, Colorado.
The earthen dam was constructed between 1966 and 1971 by the United States Bureau of Reclamation, with a height of 173 feet, 1050 feet long at its crest, and a morning glory spillway.[1] It impounds the East Fork Cimarron River for irrigation storage, as the main part of the larger Bostwick Park Project on the western slope.[2] The dam is owned by the Bureau and operated by the local Bostwick Park Water Conservancy District.
The reservoir it creates, Silver Jack Reservoir, has a normal water surface of 293 acres, and a maximum capacity of 12,820 acre-feet.[3] Recreation includes fishing, camping, boating, hunting, and hiking.[4]
