. 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 gallions 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. In the sand there is a small play ground for children. At the zero depth area of the pool there are 2 large water play features which pour water from about 10 feet (3 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 foot (0 m) to 4 feet (1.2 m), getting deeper as you walk further in to 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 in to the pool, they can be let in on the lift. The deep end of the beach has 2 floating rafts in the middle for swimmers to swim out to. The deep end also has 4 piers on the sides of the deep end for swimmers to sit and relax on without sitting on the walkway. The deep end has an NCAA and USS

 certification. The lifeguards at Centennial Beach have received annual and national recognition for outstanding aquatics safety. The lifeguards are continually ranked among best of all Ellis insured facilities. New applicants to be lifeguards at Centennial Beach begin training in the chilly water in May. Training is extremely vigorous and time consuming. Veteran guards at the Beach are also required to attend pre-season training for the season which begins at the beginning of May. During pre-season training the head-guards and veteran guards teach the new guards CPR, lifeguarding skills, and first-aid. Training six days a week for the whole month of May and continues into June depending on individual applicant's readiness.

 on Fridays so that they can practice starts and turns since the beach is too shallow to dive in to and has dark water so it is more difficult to do turns.

History

Centennial Beach was purchased by the Permanent Memorial Committee in 1931. The Committee was appointed by Judge Win Knoch, General Chairman of the Naperville Centennial Celebration, and consisted of 33 residents who each paid $500, a total of $16,500, to purchase the 45 acres (182,108.7 m²) of 1 large and 1 small limestone quarry (later merged together to create 1 swimming pool) as well as other land in Downtown Naperville near the DuPage River

 from the Von Oven estate. The actual development of the pool began in 1932 as a memorial for Naperville’s 100th Anniversary.
During the early years of the beach Naperville residents swam for free and non-residents had to pay 10 cents for children and 35 cents for adults to swim at the pool for the day. On Sundays and holidays the price went up to 50 cents per person. In the beach’s first year it made $6,000.
According to a booklet produced by the Naperville Park District in 2006 to commemorate the 75th anniversary of the Beach, in the 1930s, income from the Beach was used to finance city projects.

The limestone bathhouses were completed in 1935. To commemorate the building of the bathhouse in 1935 the Beach held its first water show.
More water shows took place at the Beach in the 1940s and 1950s, which served as a culmination of Red Cross summer swimming, water ballet, and diving classes.
Centennial Beach held its first Aquathon event in 1955. This Aquathon included community members doing water skiing demonstrations, high-dive exhibitions and synchronized swimming

.
In 1956 a similar event (to the aquathon) took place at the Beach. The fire department supplied an exciting fountain from the middle raft. The proceeds for this event went to the new fire station.
In 1969 the District assumed responsibility for Centennial Beach.
In 1970 the “Save the Beach Committee” was formed, composed 34 community members, to keep the pool from shutting down.
In 1976 the diving area was re-done, along with a new circulation and chlorination system the next year.
In 1981, when the Beach celebrated its 50th anniversary the Aquathon was resurrected with similar activities and shows to celebrate the Beach’s earlier years.
The aquathon was done again at Centennial Beach on July 8, 2006 for the Beach’s 75th anniversary. The 2006 aquathon included activities like sandcastle and sand burying contests, greased watermelon and innertube races, bozo buckets and tug-of war, kayak demonstrations, scavenger hunts, pier tag tournaments, live music entertainment, cartoonist, face painters, balloon artists, a skate challenge, a water polo tournament, and a variety of unique and entertaining water-based performances for all ages. The aquathon of 2006 was all day, from 11am-8pm.

During a significant flood on July 18, 1996, 17 inches of rain caused water levels to rise to the top of the high dive (three meters), contaminating the chlorinated water with river water and storm water. After 2 weeks and 3 days the 17 inches (431.8 mm) of waters receded, and the Beach was emptied, cleaned and refilled.
From 2002-2004 more than 2 million dollars of renovations were put in to the beach. Renovations included new concrete decks around the facility, a new circulation system, new lighting and sound systems, new staircases leading to the bathhouses and water play features.

On April 22, 2006 Centennial Beach held its first “Bottom-Feeder Ball.” The bottom-feeder ball was a birthday party for the Beach’s 75th anniversary. The bottom-feeder ball was a dinner held at the bottom of the empty quarry. The funds from this event were used to purchase the beach’s slide for the shallow end. The bottom-feeder ball began at 3:30 and had a variety of different types of entertainment that did not end until dark. The bottom-feeder ball had numerous posters for guests to look at, t-shirts to embellish, and the Waubonsie Valley High School

Urban Legends

The most widely known urban legend about Centennial Beach is of The Gremlin. The Gremlin is said to haunt the Centennial Beach break room, lurking in the shadows until he is left alone to hunt his prey: employee lunches. The Gremlin prefers the lifeguard fridge but will settle for the cashhouser fridge on a slow day. When he is not hungry, the Gremlin enjoys rearranging the contents of the fridge to make his presence known.

It has also been said that the far corner of the deep end has no bottom and is actually a portal into Narnia. The current above this portal is especially strong, this is why it is imperative that swimmers pass the deep water test before swimming in the deep end. Rumor has it that at least two patrons have been sucked into the portal and never returned, but authorities at the Park District refuse to comment on the matter.
