NotesCaption on verso: SOAP LAKE SIPHON: An interesting feature of the Columbia Basin irrigation system in Washington State is the Soap Lake siphon. The interior view shown in the above picture was taken near the the end of the 2.44 mile-long concrete bore. Boasting an inside diameter of 25 feet, the siphon carries the entire flow of the West Canal from the east side of the Grand Coulee around the northern end of Soap Lake to the west side of the Grand Coulee. --Bureau of Reclamation Photo.
