dew-pond|ˈdjuːpɒnd|
[dew n.]
A shallow pond, usually of artificial construction, occurring on downs where there is no adequate water-supply from springs or surface-drainage.
These ponds were originally thought to be fed by the condensation of water from the atmosphere, but it is now generally thought that dew plays little or no part in supplying the water.

The straw..is covered by a layer of well-chosen, finely puddled clay, and the upper surface of the clay is then closely strewn with stones. 1919Chambers's Jrnl.
