Canyon Ferry Lake, Montana

Canyon Ferry Lake is a man-made body of water that came about as a result of the Canyon Ferry Dam’s construction on the Missouri River, for the purpose of flood control. The dam was completed in 1954 and gave Montana its third-largest body of water, located 20 miles east of the capital Helena.

Canyon Ferry Lake is around halfway between Yellowstone National Park and Glacier National Park, and is thus surrounded by picturesque landscape and scenery including the Big Belt Mountains to the east, the Elkhorn Mountains to the south, and to the west the Spokane Hills.

The dam and its power plant are located at the upper end of the rock-walled canyon, about a mile away from a previous Canyon Ferry Dam and power plant that existed prior to this one.

It was built in 1896 and had its own reservoir known as Lake Sewell, although the dam and plant were demolished before the new Canyon Ferry Dam came into being. The remains were inundated and Lake Sewell was incorporated into the new reservoir.

Canyon Ferry has turned out to be one of Montana’s most popular recreation areas, in part due to its proximity to Helena, as well as Great Falls and Butte. It also has impressive views of mountain ranges like the Big Belt and covers 25 miles or more.

There are over 20 recreation sites around the reservoir which are managed by the Bureau of Reclamation. The area offers a variety of recreational opportunities including boating and water sports, three marinas, year-round fishing, camping, picnicking, wildlife viewing, and hunting, to name but a few.

Canyon Ferry Lake has also become one of the main venues for iceboat racing as well as world speed record attempts. As the lake is close to Helena, it can get quite busy during the warmer months and on the weekends.

You can access the reservoir from US Highway 12 east of Helena. Take Highway 12 south for around 10 miles before turning east onto Highway 287, which will take you to the dam after about another 8 miles.

Canyon Ferry Reservoir offers a wide range of year-round recreational opportunities, many of which are water-related and includes everything from swimming and fishing to sailing and all other kinds of boating such as motorboats, canoes, and kayaks alongside jet skiers, windsurfers and water skiers.

When the winter hits, so do the ice fishermen, ice boaters and ice skaters. There are three marinas on the reservoir, all with a variety of public recreation facilities and services.


The 76 miles of shoreline provides some great fishing opportunities. Many anglers come for the walleye, which do tend to be on the large side, although other fish species such as rainbow trout, brown trout, perch, ling, carp, bass, and pike are prevalent in the waters.

Some of the quiet spots near the land, as well as near the dam, are prime locations, as are boats out on the lake. The lake is annually stocked with rainbow trout, and the early spring is usually one of the most productive times to fish from the shore for rainbow trout.

Anglers often fish from a boat to access larger fish as the water warms up and the bass and carp start biting in the summer.

Canyon Ferry is an excellent choice for any visiting anglers and locals alike who want to try lake fishing. The area has some decent guides and outfitters and May through October, and any angler will report that Canyon Ferry is an excellent choice in terms of alternatives to the local rivers.


There are 10 different boat ramps around the lake in various regions, and all of the campsites have available boat access. There are a number of additional public boat launch areas close to the dam on the north end, as well as at the south end closer to Townsend.
