Tide Mill

A tide mill is a water mill driven by tidal rise and fall. A dam with a sluice is created across a suitable tidal inlet, or a section of river estuary is made into a reservoir. As the tide comes in, it enters the mill pond through a one way gate, and this gate closes automatically when the tide begins to fall. When the tide is low enough, the stored water can be released to turn a water wheel.

Tide mills are usually situated in river estuaries, away from the effects of waves but close enough to the sea to have a reasonable tidal range. These mills have existed since the Middle Ages, and some may go back to the Roman period.

A modern version of a tide mill is the electricity generating tidal barrage.

Famous quotes containing the words tide and/or mill:

    As the tide crept, the land
    burned with a lizard-blue
    where the dark sea met the sand.
    Hilda Doolittle (1886–1961)

    A man who has nothing which he cares about more than he does about his personal safety is a miserable creature who has no chance of being free, unless made and kept so by the existing of better men than himself.
    —John Stuart Mill (1806–1873)
