The Lake Washington Club is a non-profit membership organization located on the southeastern shore of Lake Washington near the communities of Madison Lake and Mankato in southern Minnesota.

The Club offers social members attractive grounds, a sand beach, a covered pavilion for picnics, and a boat launch. Members may also purchase slip spaces on the dock for lifts or on the shore for pontoons with sea legs.

Annual social dues provide for operations and maintenance of the grounds and annual slip fees cover installation and removal of docks and lifts for slip owners.

Please read the history of the Club and membership information. Social memberships are readily available as well as limited slip ownerships. Please contact if you have additional questions. We look forward to hearing from you! Interested in joining? Contact Kevin Hermanson 507-327-1412
