Work crews pouring an eastern "wing wall" extension to Dam #1
Visual Materials
By May of 1913, each of the three dams at the Basin was virtually complete. Here, work crews are pouring an eastern "wing wall" extension to Dam #1. By this time, with much of the original "Basin Railroad" flooded by the rising waters of the reservoir, a two-foot narrow-gauge tramway was being used to deliver mixed concrete to each work face.

Visual Materials
Photo shows the complex system of railroads and chuting employed to pour concrete the dams at Huntington Lake. Steam locomotives ran trains of three-yard dump cars from the mixing plant to each dam site. At the dam site the standard gauge trains dumped their concrete into one-yard dump cars that were pulled onto the dam on a narrow gauge track with a gasoline powered locomotive.
