List of whitewater rivers
The River Dart excepted, there is no natural whitewater in the (mainly flat) south and east of England. Here whitewater paddlers often go playboating at man made weirs. Hurley weir on the River Thames west of London is probably the most popular. There are several artificial whitewater courses, where water is pumped or diverted though a concrete channel containing obstacles to create rapids. There is a 28 m/s artificial whitewater course on the Trent at Holme Pierrepont in Nottingham (at the National Watersports Centre), a 5 m/s course on the Tees in Teesside, and smaller courses on the Nene at Northampton, and at Cardington.
