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 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.
The course is in the shape of a massive 'U', 320 metres in length, between 0.8 and 1.2 metres deep and between eight and 12 metres wide. The overall drop from top to bottom is 5.5 metres. During events a conveyor belt is used to take boats, and their occupants, from the finishing pool back to the start.
As the course has been built in a relatively flat area (flood plain), it has been built up and landscaped to create the sloping course necessary for the required rapids. Five of the six available 300-kilowatt pumps lift the water from the bottom to the start of the course, at the rate of 14 m³/s.
The channel is constructed from concrete with sloping sides. By setting river pebbles into the concrete an effect to make the course look like a natural river has been created. Large immovable rocks shape the course, as well as movable obstacles which may be used for varying the difficulty of the course and for fine-tuning of the rapids.
The total cost of construction was $AU6 million, of which $1.5 million was paid by Penrith City Council, $1.5 million by the International Canoe Federation (including $300,000 by Australian Canoeing) and $3 million by the Government of New South Wales.
