On examination the erosion that had taken place was far worse than expected. The foundations were uppercut 9 inches to a depth of 2 feet and showed three distinct leaks. 8 feet from the wall the level was found to be 4 feet below the foundations and 30 feet from the wall, 5 feet below the foundations. Work was commenced immediately to repair the damage. Up to date approximately 80 c. yds. of concrete has been placed in repairing the foundations and building concrete aprons. There still remains one large apron to be constructed and some work on the sides of the reservoir wall. A 12 inch sluice valve was installed while this work was in progress. “The maximum level of the reservoir below the spillway this year to date has been 23 inches, today’s reading is lSi inches.
