The Penrith Whitewater Stadium is located near Sydney, Australia. It is an artificial whitewater sporting facility which hosted the canoe/kayak slalom events at the 2000 Summer Olympics in Sydney. The facility is part of the Penrith Lakes Scheme, which is converting open-pit sand and gravel mines into lakes for recreation. It is close to Cranebrook, New South Wales and is adjacent to the Sydney International Regatta Centre. These lakes are not filled via the Nepean River, but are filled via rain water and ground water. The operation of the facility aerates the water and improves water quality in the flat water rowing and canoeing course.
