About Round Lake
We have been on Round Lake since 1999.
We have been on Round Lake since 1999.
Round Lake is one of the Sister Lakes in Van Buren County, Southwest Michigan, located near Dowagiac, Michigan. It is a clean, quiet inland lake with calm conditions that are ideal for wakeboarding, wakesurfing, waterskiing, and wakefoiling. Morning sessions on Round Lake are especially good. The community here has a long history of watersports and families have been coming to Sister Lakes for generations.
Bill Boston grew up on these lakes. He opened The Boarder Line on Round Lake in 1999 after seeing that nobody in the area was offering real watersports instruction or selling gear that serious riders could trust. Over the past 25 years the shop has grown into a full Nautique and Barletta dealership with a structured lesson and camp program, indoor heated storage, and a pro shop stocked with gear the staff actually rides.
Whether you are looking for wakeboard lessons near Round Lake, wakesurf coaching on Sister Lakes, a Nautique dealer in Southwest Michigan, wakeboard camp for your kids, or a trusted place to store your boat through a Michigan winter, this is where you come.
