Welcome to the home of FLOW Swimmers (Flathead Lake Open Water Swimmers), where THE LAKE is open year-round (when it's not frozen over)! Situated on the lake's southern shore, we are not just about embracing the exhilarating challenge of open water swimming; it's a celebration of the unique spirit and community that Flathead Lake inspires. Each stroke in these pristine waters isn't just a swim; it's a connection to nature, a testament to the purity of our environment, and a journey into the heart of what makes open water swimming an unparalleled experience..
"Clean, swimmable open water is my passion, and a portion of ALL of our proceeds go toward clean water initiatives on Flathead Lake." — Mark Johnston
