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:
“the tide lays down its wet throat
and alters the land to island—even as I watch
I say there is no shore
apart from stories of it,
no smoke, no hut, no beacon ...”
—Lynn Emanuel (b. 1949)
“—First a shiver, and then a thrill,
Then something decidedly like a spill,—
And the parson was sitting up on a rock,
At half-past nine by the meet’n’-house clock,—
Just the hour of the Earthquake shock!
MWhat do you think the parson found,
When he got up and stared around?
The poor old chaise in a heap or mound,
As if it had been to the mill and ground!”
—Oliver Wendell Holmes, Sr. (1809–1894)
