CONT

Excavations for the cut-off trench began on June 1, and were completed by the end of the month. Suitable material excavated from the trench was placed in the embankment. Following excavation of the trench, the cut-off wall footing was cut into bedrock to a depth of three feet. Placement of the cut-off wall followed excavation of the footing and was completed by the end of july. The cut-off wall extends across the bottom of the trench and up both abutments and provides a water-tight seal between the dam and foundation.
