Nestled along the southeastern shore of Lesser Slave Lake, roughly 255 kilometres northwest of Edmonton, this northern Alberta community sits at the crossroads of Highway 2 and Highway 88. The surrounding area falls within the Municipal District of Lesser Slave River No. 124, and the town functions as a regional service centre for communities throughout the area. The administrative offices of the Sawridge First Nation are also based within the town.
A History Shaped by Flood, Fire, and Resilience
The earliest recorded European presence in the area dates to 1799, when British explorer David Thompson passed through. In the years that followed, British fur traders established several trading posts in the region, including a Hudson’s Bay Company post near the mouth of the lake. A community took shape around these posts and was known for many years as Sawridge. The name was changed to Slave Lake in 1923. A severe flood in the 1930s devastated much of the original settlement, prompting residents to relocate and rebuild on higher ground at the town’s current site. Slave Lake was officially incorporated as a town in 1965. Flooding returned in July 1988, when Sawridge Creek again inundated parts of the town. The community faced an even more dramatic crisis in May 2011, when a major wildfire driven by strong winds tore through the area. Provincial officials reported that roughly 40 percent of the town was destroyed or damaged, including the town hall, the public library, a radio station, a shopping mall, and a large number of private homes. All residents were ordered to evacuate. Remarkably, no civilian deaths or injuries were recorded. Tragically, a firefighting helicopter crashed into Lesser Slave Lake near Canyon Creek on May 20, 2011, and its pilot lost his life. In July of that year, Prince William and Catherine, the Duke and Duchess of Cambridge, visited Slave Lake to show support for the rebuilding effort.
