In our previous Report it was proposed to construct a

buttress to lend additional support to the rock fill, but it

was afterwards decided that it would be preferable to fill

with concrete the space previously occupied by the sand, and

this work is approaching completion.

LEAKAGE

The exploratory work has shown that the reinforced

concrete core wall was in good condition, although it had

moved at the top, and therefore the main cause of the leakage

must be sought elsewhere.

Measurements of the discharge of the underdrains

indicate that the leakage practically ceases when the

reservoir is drawn down about 30 feet, and further

exploratory work will be undertaken to endeavour to locate

and stop it.

We are sending a copy of this letter to the Director

of Public Works, Hong Kong.

We are, Gentlemen,

Your obedient servants,

BINNIE, DEACON & GOURLEY.
