The City of Lewisville operates two seasonal outdoor aquatic facilities, Sun Valley Aquatic Center and Old Town Aquatic Park. Both facilities were constructed in 2005 and have attracted visitors from around the metroplex.  Seasonal aquatic offerings include: swim lessons, swim team, partybrella rentals, and the Annual Doggie Dive-In. At this time, no lifeguard training is being offered.
