Shin Mun Dam Site.

My partner, Mr. Gourley, re orted 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 possi-

bilities for increasing the water supply of Kowloon and Hons dong

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 a tructure 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 4# he endorsed Mr. Henderson's view that

the Shin 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 2,300 mill. gall. ross, or about 1,850 mill. gall. above

the level at which the water could be discharged by gravity

into the conduit

By raising the top water level to 625 U.D., i.e.

another 25 ft. it was pointed out that the storage capacity would be increased by about 1,000 mill. gall.

Acting on the advice which was then given a Contract

was let on the 30.4.31. for the exploratory work in order
