Soaking a swathe of Montana’s Missouri River Country, Fort Peck Lake (really a reservoir) is the state’s largest body of water. Its 1,520 miles (2,446km) of shoreline outnumbers the length of the Californian coast and is home to the Charles M. Russell National Wildlife Refuge, populated by herds of mule deer, red foxes, mountain bluebirds, coyotes and so much more. The lake was founded with a practical use in mind – to alleviate flooding, as well as post-Depression poverty by creating jobs – but has evolved into a hub of outdoor recreation.
