Solid rock in the stream bed lies beneath a layer of sand, gravel, and boulders,
so deep as to render closure between the dam structure and the underlying
bedrock impracticable. Test holes were carried to a depth of 100 feet below the
stream ...

The presence of adequate foundation rock for dams of the masonry and concrete
types occurs principally in the mountain areas where the stream beds are steep
and afford little impounding capacity. Such sites are generally too expensive to ...
