the downstream part which was brought up during the wet
season of 1934. The thrust block, that is the concrete portion of the dam, is now completely built up to level 530 with the rockfill only slightly below this level.
It was
announced last year that the estimated expenditure for 1934 was $2,020,000 and that that for 1935 would be $2,400,000, and that it was hoped to bring the dam up to level 530. Actually the dam is at 530 now, a good three months in advance of the estimated time, while the actual expenditure to date is less by about $100,000 than the estimate for building the dan to this level. The total expenditure for 1934 and 1935 will be about $150,000 more than the figures given last year, but the progress will be correspondingly advanced. Up to the present about 100,000 cubic yards of concrete and 225,000 cubic yards of rockfill have been placed in the dan more than half the total, and it is expected now that if the present rate of progress can be maintained the thrust block will be finished entirely in July or August, 1936, and the rockfill, Overflow and Valve Shaft, etc. by the Spring of 1937.
Towards
the end of 1934 a start was made on the construction of the
Pineapple Pass dan. This work has also gone well during the year. The core trench, 73 feet deep, has been concreted up to ground level and the embankment itself is up to level 565
