Canyon Ferry Lake is a large reservoir located about 20 miles east of Helena, Montana. Created by the Canyon Ferry Dam on the Missouri River, it covers approximately 35,200 surface acres with 76 miles of shoreline. The lake's substantial size and proximity to Helena make it a popular destination for various water activities, including paddling.

Access to the lake is excellent, with over two dozen designated access sites surrounding its shores. Three marina concessions - Goose Bay Marina, Kim's Marina, and Yacht Basin Marina - provide boat launching facilities, camping areas, and small stores. Additionally, the Bureau of Reclamation maintains campgrounds, day use areas, and concrete boat launches around the lake.

Paddlers will find diverse scenery, with views of the Big Belt Mountains to the east, Elkhorn Mountains to the south, and Spokane Hills to the west. The lake's substantial size can lead to challenging conditions, particularly due to frequent high winds. Kayakers and canoeists should exercise caution and be prepared for potentially rough water, especially in open areas of the lake.

Wildlife viewing opportunities abound, with the chance to spot pronghorn antelope, mule deer, and white-tailed deer along the shores. A wildlife management area at the southern end of the reservoir is home to a colony of terns and pelicans. Birdwatchers may also encounter Chestnut-collared Longspurs and Long-billed Curlews in the upland areas.

Fishing is a popular activity, with rainbow trout, perch, walleye, and ling being common catches. Anglers should be aware that a fishing license and Aquatic Invasive Species Prevention Pass are required.

While the lake is open year-round, the most favorable conditions for paddling typically occur from late spring through early fall. Water temperatures can be brisk even during summer months, so appropriate gear is recommended. Paddlers should also be aware of motorized boat traffic, which can be heavy, especially on weekends and holidays.
