Formation of Wong-nei-Chung should be seriously considered for a large Reservoir in the area retained.
The Valley drains a large area and it would be better for the service if the City of Victoria could be supplied from that end, on account of the great length and comparative narrowness of the City.
With such a rough description of the subject which is to be considered, I forward:
1. Plan of Victoria showing Means & Levels
2. Plan of Pokfoolum
3. Section on trial line along hill side from do.
4. Plan of existing Reservoir
5. Section through present dam
6. Copy of Surveyor General's report Sep. 72
7. Tables of rainfall since 1867
8. Calculated overflow at Pokfolum Reservoir for year 1872
It will be seen from the present state of the investigation that estimates have not yet been prepared. A contoured plan of the Island by Col. Collinson R.E. is published in London, and is therefore not included in the information.
In fine, I would urge strongly on Government the propriety of obtaining for this office the assistance of a good surveyor to collect and compile information for the Surveyor General, who would thus be able to submit with confidence to the Government a complete scheme.
At present, such is the pressure of work that no one in the Department can be spared for this duty.
A scheme prepared as I have indicated might be afterwards corrected or altered by the best Authorities in England, and with the faults eliminated in this way, the Colony would possess a plan the execution of which could not fail to end in success.
I repeat that it is only by the wise combination...
