Competition pool[edit]

The main competition pool of the Natatorium is 50-meters with eight racing lanes. Two moveable bulkheads allow for long or short course events as well as hosting water polo and synchronized swimming. The seating capacity of the Natatorium is 4,700, making it the largest indoor pool in the United States. There is also room for additional seating of 1,500 on deck. The depth of the pool is 9 feet (2.7 m) at the ends and 10 feet (3.0 m) at center of pool. Water temperature is kept at 79 °F (26 °C). The main pool contains six underwater windows for television and coaching analysis. There are approximately 1,000,000 US gallons (3,800,000 l; 830,000 imp gal) of water in the main pool. There have been 101 American records and 15 world records set in the pool to date.[1]

Diving well[edit]

The diving well of the Natatorium has hosted many local and national diving events, including the 2008 Olympic trials. The diving well has a depth of over 17 feet (5.2 m) and holds more than 450,000 US gallons (1,700,000 l; 370,000 imp gal) of water. It has four 1-meter and four 3-meter boards as well as five diving platforms of 1, 3, 5, 7.5 and 10 meters in height. The pool is kept at approximately 86 °F (30 °C). There are also two underwater windows for television coverage and coaching analysis.[2]


The Natatorium was completed in 1982. Counsilman-Hunsaker served as design consultant for the project. The architects were Browning, Day, Pollack & Mullins, Inc. and Edward Larabee Barnes, Architects. This premier competition pool has been recognized as one of the fastest pools in the world with world and American records set by athletes from many countries.

The facility hosted the 2008 Olympic Diving Trials. It was the fifth time since 1984 that the city of Indianapolis had hosted the swimming and/or diving trials, and the city of Indianapolis has recently announced that the Natatorium will again host Olympic Trials for diving in 2016. The Natatorium was used as the trials site every four years from 1984 to 2000. In addition, the Natatorium building houses the IUPUI Recreation Program in the basement of the facility, including the state of the art Polaris weight room which was built in 1996.

Popularly known as IUPUI, this facility has been host to numerous other swim events including the 1982 National Sports Festival, the 1987 Pan American Games, the 2001 World Police and Fire Games, NCAA Championships, USA Swimming National Championships, and the Big Ten Championships. Additionally, in July 2009, IUPUI hosted one of USA Swimming's most elite competitions, the 2009 ConocoPhillips National Championships.[3]

As part of the agreement for being selected to host the 2016 USA Diving Olympic Trials, the Natatorium underwent roughly $18 million in renovation and repairs before 2016. The project will include a new roof and improved climate control. According to local television station WTHR, "the venue cost $21 million to build in 1982, and would cost nearly $75 million to replace."[4]
