The excavation for the foundations of the 2 Dams proceeded slowly. The depositing of the concrete for the foundations of the second Dam was delayed by reason of a soft pocket in the rock at the South end of the Dam. This necessitated the foundations of the dam being carried down to 575 A.O.D. and constant pumping was required to cope with the spring water met with. The depositing of the concrete to the Dam in question began in April and by the end of the year 1,500 c. yds. of fine cement concrete and 3,750 c. yds. of displacer cement concrete have been deposited. 160 c. yds. of cement concrete inner face blocks, and 190 c. yds. granite rubble back facing have been laid by the end of the year, when this Dam has reached a level of 625 A.O.D.

Concrete to the Draw-off Dam (the 1st Dam) commenced in October, and by the end of the year 520 c. yds. of fine cement concrete and 220 c. yds. of displacer concrete have been deposited.
