Looking north on July 31, 1906, the floor of the extended channel is cleared to begin construction of the Butterfly Dam as excavation of the rock downstream of the terminal wall proceeds in the background. As rock removal proceeds, the east wall of the extended channel at right and the west wall at left will be constructed to fill the gap between the original and extended channel. (MWRD photo 3288N)
