This Canadian Lake Hides an Underwater Ghost Town

Lake Minnewanka in Alberta was once home to a bustling resort, but today its eerie landscape can only be seen by scuba divers

On the surface, Lake Minnewanka in Alberta, looks like most other large bodies of water in Canada. Ringed by stands of evergreen trees and nestled near the eastern edge of what is today known as Banff National Park, the 13-mile-long lake has been a focal point within the park for years, drawing kayakers, hikers and bicyclists to its chilly, crystalline waters. But many visitors don't realize that the lake, as it appears today, is a modern addition to the natural landscape, and that the area, before it was flooded, was home to a bustling lakeside resort town that today can only be visited with scuba gear.

Known as Minnewanka Landing, the summer village located at the base of the Canadian Rockies had lured city dwellers from nearby Calgary for years, most notably beginning in 1886 with the completion of the Beach House, a hotel constructed out of logs. Over the years the town grew to include four avenues, three streets, dozens of cottages, numerous hotels and restaurants, and multiple sailing outfits that would take guests on boat excursions around the (much smaller) original lake.

It wouldn’t be until 1912 that the area’s landscape would start to evolve with the construction of a new dam—part of a Calgary Power Co. hydroelectric plant operation being set up downriver—resulting in the flooding of a good portion of Minnewanka Landing. But while the town continued to thrive over the next two decades (42 lots were built to make way for additional cabin sites), it would finally meet its fate in 1941 with the building of a new dam, which raised the reservoir’s waters by 98 feet, engulfing everything in its wake.

“It was during the Second World War and everyone was hungry for power,” Bill Perry, an archeologist with Parks Canada, tells “Calgary and the surrounding area were growing substantially during that point in time and required more power, so Lake Minnewanka was seen as an easy end.”

Today the reservoir hides a secret that many people will never get the chance to experience—unless they're scuba divers, that is. Thanks to Lake Minnewanka’s glacier-fed, ice-cold waters, many structures of the former resort town still remain intact, including house and hotel foundations, wharves, an oven, a chimney, a cellar, bridge pilings and sidewalks. (A full list of sites is available here.) Even the footings from the town’s original dam, built by the federal government in 1895, along with the footings from the dam built in 1912, remain visible.

Another notable site nearby is a native campsite that dates back thousands of years. In recent years, archaeologists have uncovered spear points, arrowheads, ancient weapons known as atlatls, stone tools, and other implements used by indigenous tribes who once lived there.

“What is particularly interesting about that for me is looking at the whole area as a cultural landscape,” Perry says. “The area's 13,000 years of continuous use absolutely fascinates me.”  

And Perry isn’t alone. He estimates that approximately 8,000 divers descend into the lake each year to explore its hidden past.

“Because of the cold, clear water, wood actually survives quite well down there,” he says. “That’s why it has become such a popular diving place for local scuba diving clubs. There's just so much left to see."
