sumption of water to the quantity which could be supplied by pumping, thus obviating recourse to further restrictive measures. By the 7th June, sufficient rain had fallen to admit of the gravitation reservoirs being again drawn upon to the necessary extent and constant supply by house-services in the Rural Main Districts was therefore restored on that date and was maintained throughout the remainder of the year.
The total quantity of water stored in the impounding reservoirs on the 1st January amounted to 1,173.10 million gallons. It reached a minimum on the 2nd June when it amounted to 440.17 million gallons, the contents of the gravitation reservoirs, which were in a very muddy condition, being then only 12.29 million gallons.
The reservoirs were at or over their permanent overflow levels for the following periods:
Reservoir Capacity to permanent overflow level. (Million gallons.) Period Taitam,The rainfall for the year amounted to 101.60 inches (Observatory record) or 18.44 inches above the average; June, August and September being specially wet months. The rainfall for the period, May to September inclusive, which is regarded as the "wet season" was 26.79 inches above the average.
The maximum quantity of water impounded in all the reservoirs amounted to 2,151.86 million gallons on the 21st September or 538.54 million gallons more than the maximum during 1917.
The total quantity of water remaining in the reservoirs at the end of the year amounted to 1,783.95 million gallons.
The defects in one of the new pumping engines, recorded in last year's Report, which rendered it unfit for service, had not been remedied by the close of the year, but the necessary repairs were in progress. The other new engine was serviceable during the early months of the year and had been repaired and put in thorough working order by the 17th December on which date it was re-started. The latter ran from the 1st January to the 15th June and from the
