In the 1950s, Lewisville Lake served as a municipal water source for Dallas. Over the next half-century, it evolved into a popular summertime attraction, even hosting a number of large-scale bass-fishing tournaments. In 2011, Lewisville Lake added a new distinction: it became the office of Boomerang Boat Club. Dedicated to getting people on the water at a low cost, the company rents its fleet of pontoon/deck boats and ski boats for full- or half-day excursions.

Lewisville Lake's waters, fed by the Trinity River and sustained by the Lewisville Dam, provide a placid canvas for boating. Before disembarking from Westlake Park, boaters can shimmy into life jackets and load the deck with snacks, provided they are not packaged in glass, grilled on board, or pilfered from a child's sand castle. As passengers settle in, convivial dockhands provide a basic orientation and answer any questions. Upon request, they also outfit boats with tubes and ski vests.
