The U.S. National Whitewater Center is a non-profit outdoor recreation and athletic training facility for whitewater rafting, kayaking, canoeing, rock climbing, mountain biking and hiking which opened to the public on November 4th, 2006. The Center is located in Charlotte on approximately 400 acres (1.6 km2) of land adjacent to the Catawba River. The USNWC is an official Olympic Training Site for whitewater slalom racing.
The creators of the Center were inspired by the Penrith Whitewater Stadium built for the 2000 Olympics. The Center's primary feature is the world's largest and most complex recirculating artificial whitewater river. The facility cost $38 million to build and costs $6.8 million per year to operate.
The Center's recirculating river is filled with 12 million gallons of well water, which is cleaned every 24 hours by a filtration and ultraviolet system. The whitewater portion of the river has a total of 3,750 feet (1,140 m) of channel divided between two channels: the Olympic-standard slalom competition channel and the longer wilderness channel, which splits around an island at the top. The rapids are Class II to IV and can be navigated via canoe, kayak or a guided raft. The different channels are linked by an Upper and Lower Pool which are connected via a moving-belt boat-lift conveyor.
Each channel is watered by three of the seven 680-horsepower pumps. Six pumps will water both channels simultaneously. The electricity cost of each pump is about $45 per hour. When only one channel is used, an inflated barrier rises up from the bottom to prevent water from entering the unused channel. Since both channels have the same drop, 6.4 metres (21 ft), the extra length of the long channel gives it a gentler slope.
