Anchor
An anchor is a device, normally made of metal, used to connect a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin "ancora", which itself comes from the Greek ἄγκυρα ("ankura").
Anchor Dam
The concrete thin-arch dam was completed in 1960 by the United States Bureau of Reclamation as a water storage project. The -high dam structure impounds the water of the South Fork of Owl Creek, with the spillway as designed as a central overflow "notch".
