Bureau of Reclamation, Montana.
Canyon Ferry Dam and reservoir are located in Montana about 50 miles downstream from where the Gallatin, Madison, and Jefferson Rivers join to form the Missouri River. The reservoir has approximately 35,200 water surface acres, 9,360 land acres and 76 miles of shoreline, and offers excellent fishing opportunity for rainbow trout, perch, ling, and walleye. There are three marina concessions (Goose Bay Marina, Kim's Marina and Yacht Basin Marina) on the reservoir which provide a variety of public recreation facilities and services such as boat launching, camping, rental docks, small stores, etc. Reclamation also provides campgrounds, day use and picnic areas, concrete boat launches, and a seasonal visitor center. A wildlife management area at the end of the reservoir is managed by the Montana Department of Fish, Wildlife and Parks and is home to a colony of terns and pelicans. The upland areas around the reservoir provide habitat for Chestnut-collared Longspurs and Long-billed Curlews, as well as hundreds of Pronghorn antelope, mule deer and white tail deer.
