Crew members from the L.A. City Bureau of Power and Light (DWP predecessor) live in tents as they reconstruct Power House 2, which was destroyed when the St. Francis Dam broke just above it on March 12, 1928.
This 8x10-inch print is a bit later than this photograph, in that there are more tents, and the turbines at center-bottom have stopped spewing water.
The Power House 2 community is completely gone; it was at center-top.
