Different size regulations apply for other pool-based events, such as diving, synchronized swimming, and water polo.
[1] Some style guides caution against the hyperbole of describing any relatively large pool as "Olympic-size[d]".
[3] If the pool is used for Olympic Games or World Championships, then the minimum depth is increased to 2 metres (6 ft 7 in).
Twenty-five world records were broken at this pool, although this is more heavily attributed to the polyurethane “supersuits” worn by many competitors (banned by FINA in 2010).
[5] The increased depth of the pool assists the lane lines in dissipating water churn, thereby creating less hydrodynamic drag.
