Fort Peck Reservoir, Montana's largest body of water, is home to over 50 different species of fish. Stretching approximately 134 miles in length and boasting a maximum depth of 220 feet when full, it features over 1,520 miles of shoreline, surpassing even the California coast in length. Constructed from 1933 to 1937 by building a 3.8-mile-long dam across the Missouri River, the reservoir offers prime fishing opportunities for various sought-after species such as walleye, northern pike, paddlefish, sauger, lake trout, smallmouth bass, and chinook salmon.

Access to the reservoir is facilitated by a paved road for larger vehicles leading to Fort Peck Marina, located near the west side of the dam. Other access roads, albeit gravel or dirt, lead to Hell Creek Bay, situated 26 miles north of Jordan, and Rock Creek Bay, approximately 10 miles west of Highway 24. All marinas are equipped with concrete boat ramps. Surrounding this expansive water body is the Charles M. Russell (CMR) National Wildlife Refuge, managed by the US Fish and Wildlife Service, offering over one million acres of public land for fishing, hiking, hunting, camping, bird-watching, and other outdoor recreational activities. However, it's advisable to check the weather conditions before accessing the reservoir's dirt roads, as they can become impassable when wet.

To reach Fort Peck Reservoir, one can access it from various directions. From the west, travelers can turn off US Highway 191 northwest of Lewistown at the Fred Robinson Bridge. From the south, access is available from Montana Highway 200 at Jordan, then heading north via the county road. The eastern edge of the reservoir can be reached from Montana Highway 24, passing through the town of Fort Peck and over the dam. However, the north side of the reservoir is less accessible from main roads, with US Highway 2 between Glasgow and Malta being the closest paved road. Numerous county roads branching south from Highway 2 provide access toward the reservoir
