The Spring Meadow Lake Cardboard Cup Regatta is a family fun event sponsored by Montana Fish, Wildlife and Parks and Spring Meadow Resources. Building a boat requires some imagination, there are no size restrictions and the boat may be as big or small as the participants wish. However, the boat must be made of corrugated cardboard and pass a boat inspection before racing. No matter how fast, slow, big or small, sensible or outrageous, the first rule is to have fun. This event is as much fun to watch as it is to participate in. S0, come out to Spring Meadow Lake and join the fun!
