Rock-fill dams are embankments of loose rock with either a watertight upstream face of concrete slabs or timber or a watertight core.
Earth dams, also called earthen and earth-fill dams, are constructed as a simple homogeneous embankment of well-compacted earth, sometimes with a watertight concrete or clay core or upstream face, or sometimes with a hydraulic fill to produce a watertight core.
A type of temporary earth dam occasionally used in high latitudes is the frozen-core dam, in which a coolant is circulated through pipes inside the dam to maintain a watertight region of permafrost within it.

Grand Coulee Dam, one of the world’s largest concrete dams, is used for flood control, river navigation, irrigation, and power production that services the varied manufacturing in the area.
Power generated at the dam is used to pump water into Grand Coulee, a vertical-walled gorge, c.30 mi (48 km) long, carved by the Columbia River through the Columbia Plateau.
The coulee, dammed at each end, is used as a reservoir (Banks Lake); it supplies water to more than 500,000 acres (202,343 hectares) on the plateau and acts as a backup against pump and power failures.
