 Seventeen miles of railroad track were privately built to carry materials from quarries at nearby Cranberry and Silver Lakes to the dam site; this spur railroad and a highway network had to be built to move supplies into place.A camp for the workers and their families had to be constructed, along with facilities such as schools for their children.To prepare for the dam construction, each individual lot of land was condemned and appraised, and the owner paid a "fair value" for the land.
