CHAIRMAN’S ADDRESS. KLY. 
increasing to the figures I have assumed, which will probably 
be proved to be not an incorrect estimate, should be sufficient 
to arouse public interest on the state of the water supply, 
and the absolute necessity of making immediate provision 
for the future. It must now be obvious that Sydney cannot 
any longer place any dependence upon the daily flow of the 
streams supplemented by storage, unless the storage is 
regularly and systematically provided for as the demand for 
water increases. Hven Melbourne, with its splendid stream 
flow from the mountain slopes, has been rudely awakened 
to the necessity for greater storage. 
Cataract Dam was commenced five years ago, and has 
only just been completed. I have shown from the records 
of past rainfall, that in five or six years we shall be in urgent 
need of more storage than we at present possess, in order 
to maintain the rate of consumption which I have assumed 
will be reached by that time, otherwise the citizens may 
expect to be called upon to submit to restrictions again. 
If we are prudent, therefore, we should lose not a moment 
in deciding where such storage should be made, and 
commencing the works in connection therewith. 
Sites Available for Reservoirs on the Existing Catch- 
ment Area.—It is well known that on the Cordeaux, Upper 
Nepean, Avon,and Bourke rivers, within the catchment area 
supplying the present water system, there are several good 
sites for reservoirs, three of which were actually surveyed 
by the Royal Commission of 1902, and estimated to impound 
27,000 million gallons, so that ali that would be necessary 
would be to select one of them, and set about building the 
dam. When completed, say in five years’ time, it would 
be ready to supplement the storage at Cataract, the water 
from it being made available in the same manner as at 
Cataract, by allowing it to run from the dam into the river 
channel, ultimately to find its way into the existing 
conduit which supplies Prospect reservoir.
