Sir,
Enclosure No. 1.

Hong Kong, 21st October, 1931.
The Hon. Director of Public Works,
Hong Kong.
Hong Kong Water.
Shing Mun Dam Site.
My partner, Mr. Gourley, reported in favour of the
Shing Mun Scheme as proposed by Mr. Henderson in 1924 after
a review of the further needs of the Colony and other
possibilities for increasing the water supply of Kowloon and
Hong Kong.
His conclusions are set out in paragraph 70 of his
report to the Crown Agents of the Colonies dated 1. 4. 31.
In paragraph 42 of this report he pointed out that
in view of the magnitude of the structure it would be
necessary to explore the foundation conditions before we
could make any final recommendation and advised that
exploratory work should be promptly put in hand, which work
would also be necessary before drawings could be prepared.
In paragraph 44 he endorsed Mr. Henderson's view
that the Shing Mun Valley should be developed to its utmost.
It had originally been proposed to store water to a
maximum depth of 175 feet which would form a storage
reservoir of 2,000 mill. gall. gross, or about 1,850 mill.
gall. above the level at which the water could be discharged
by gravity into the conduit.
SB
My raising the top water level to 625 0.D., i.e.
another 25 ft. it was pointed out that the storage capacity would be increased by about 1,000 mill. gall.
