2012 Olympic venue
The lake was used as the 2012 Summer Olympic venue for rowing and canoe sprint, and as the 2012 Summer Paralympic venue for rowing. For the duration of the Olympics, the lake was officially referred to as Eton Dorney; confusingly, a separate venue in Stratford was called Eton Manor due to 19th century associations with the school.
To provide for Olympic spectators, the existing facilities were enhanced to include 20,000 additional seats; most of these seats were temporary. Construction began in October 2009, following investigations by Oxford Archaeology, of enhancements to Dorney Lake, including a new cut-through between the competition lake and the return lane, a new bridge and an upgraded access road, funded by the Olympic Delivery Authority (ODA). During the Olympic events, Dorney Lake was staffed by around 3,500 personnel including volunteers; it could accommodate up to 30,000 spectators per day. A temporary bridge linked the Dorney Lake site to Windsor Racecourse, where a pick-up and drop-off point for Olympic spectators was established. Other access options existed for walkers and cyclists.
