Tidal barrage. Swirling water entering through sluice gates on a tidal barrage. Built on the Rance river, France, the barrage opens sluice gates when the tide is rising (as here) to fill the estuary which acts as a reservoir. When the tide falls the sluice gates are closed and the water is released only through the 24 turbine generators. This dam is located at a point where the tidal range can reach up to 13.5 metres. It is 750 metres long and creates an artificial lake 22 square kilometres in area. The generators can produce a total of 240 million watts of power.
