Technical Details

All first-time visitors to Dorney Lake without fail experience 'the wow factor' and many people ask about the 'ins and outs' of construction, how the Lake is kept in pristine condition and all sorts of peripheral questions. Here are some details:

  • For many years pre-construction fertiliser use was restricted on the then fields to ensure high-quality water
  • The main Lake is 2,200 metres long
  • The requirement set by the Fédération des Sociétés d'Aviron (FISA), the international rowing authority, for world-class rowing courses is a minimum of 2,000 metres
  • The Lake has eight lanes, each 13.5 metres wide
  • It is a minimum of 3.5 metres deep
  • This depth standard provides the body of water necessary for racing boats to perform at optimum effectiveness
  • The parallel Return/Warm-Up Channel is up to 5 lanes wide and is 2.5 metres deep
  • The astounding amounts of 4 million tonnes of gravel, 1,970,000 cubic metres of topsoil and subsoil and 585,000 cubic metres of basal clay were extracted during construction of the main Lake and Warm-Up Channel
  • The project took over 10 years until completion in 2006
  • To minimise disruption to the local community material extracted was removed on a special conveyor belt to a point two miles away for collection by lorry there.
  • The Lake is fed from underground aquifers (streams) percolating through a natural gravel filter.
