Picture caption: April 12, 1925 Diversion Dam and Second Borrow Pit.
In the lower right corner is a temporary dam to direct water and sand being washed out of the pit into the large pipe. From here it goes to the dam. This pit seems to have run on gravity, as there is no dredge pump visible. In front of the houses built for use during construction and removed after completion of the project you see the Conduit, behind that is a dragline working.
