Centennial Beach is a public aquatic park located at 500 W. Jackson Avenue in Naperville, Illinois. The Beach is within an abandoned, double quarry alongside the DuPage River. The facility covers almost 6 acres (24,000 m²) of land with a full two acres (8,000 m²) or 6.2 million gallons of open water from lake Michigan, all tested, re-circulated and chlorinated on site. Among its features is a sand beach next to the shallow end of the pool which offers a zero-depth entry. At the zero depth area of the pool there are 2 large water play features which pour water from about 10 feet (3.0 m) up, and water spouts that shoot up water for children to play in and cool off. The shallow end of the pool goes from 0 feet (0 m) to 4 feet (1.2 m), getting deeper as you walk further into the pool. In the 4 feet (1.2 m) area there are 3 lanes for lap swimmer’s, where Centennial Beach’s swim team, The Mudrats, practice each week day morning before open swim hours. The shallow end also has a slide that was added in 2008. The shallow end also has an area called the “channel.” This area is right next to the deep end and the diving boards. In the channel there is a pool lift for people who cannot use the ladders to get into the pool, they can be let in on the lift.
