The River Thames is one of the main rowing areas in England, with activity taking place on the Tideway and on the 45 separate lock reaches on the non tidal section. The river hosts two major rowing events The Boat Race and Henley Royal Regatta, and a large number of other regattas and long distance events take place on the river. Dorney Lake in Buckinghamshire was opened specifically as a rowing lake besides the Thames and has become the venue for a few events that formerly took place on the river. Other lakes adjacent to the Thames are the Redgrave Pinsent Rowing Lake and Royal Albert Dock. Rowing, or sculling, includes skiffing, dinghy racing and cutter racing in which the boats are also propelled by blades.
