capacity of 2,118 million gallons, which are fed by 3,222

acres of direct and indirect catchment.

We have made our own estimate of the present main-

tainable yield of these sources and, altogether, it amounts

to 8.25 million gallons a day 8.25 M.G.D.

On the completion of the Aberdeen Works as set out

in Sessional Paper 4/1928 Page II, the total storage will be

increased to 2,408 million gallons and the catchment area to

4,672 acres with an estimated corresponding maintainable

yield of 10 ̊80 M.G.D.

On the completion of the remaining works

-only set out in the above-mentioned Sessional Paper, the

total catchment area will become 6,051 acres, and the total

maintainable yield of the Island Works will be 1285 M.G.D.

We are of opinion that with the completion of the

works mentioned in the preceding paragraph, the total resources

capable of economical development will have become exhausted,

and that further supplies must come from the Mainland.

The difficulty of forecasting the water requirements

is not lessened by the knowledge that in only four complete

years -1908, 1919, 1920 and 1921 since 1906 has a full and un-

restricted supply been given, due to the fact that the con-

struction of new works has never kept pace with increasing

consumption and at times has been seriously in arrears.
