From 1908 to 1920, American settlers, many of whom were descendants of French Canadians who had earlier immigrated to the United States, came to St. Brieux.

[7][8] St-Brieux Catholic Church features stained glass windows by Rault Frères (Brittany) Franc.

The campground is well treed in a forest of aspen and has electrical hookups, modern washrooms, coin operated showers, and a sewer dump.

Fish commonly found in St. Brieux Lake include walleye, northern pike, and perch.

There are municipal and Roman Catholic cemeteries, a replica of the first church in St. Brieux, and an historic monument to the original settlers.
