Powerboats are restricted to Upper and Middle Waterton lakes in Waterton National Park. Boat launching ramps are available at the marina in the town site and at the Linnet Lake picnic site on Middle Waterton Lake. The marina also has fuel and mooring sites available.
Water-skiing is popular on Middle Waterton Lake, especially when conditions are calm. The water is very cold, so dry suits or full wetsuits are strongly recommended for all water skiers. Be aware that floating logs are common and can pose a serious hazard to boaters, and particularly water skiers.
