THE VALUE OF IRRIGATION. 
the top. The waters of the Murrumbidgee -will be thrown back to 
form a lake stretching in one direction 41 miles, in another 15 miles, 
and in a third 25 miles. ; 
The construction is well in sees : 
advance of settlement re- 
quirements. — Burrinjuck, 
the point at which the dam 
is constructed, is a long 
distance from the irrigation 
areas. From the dam itself 
the water flows down the 
Murrumbidgee for 220 
miles, where at a point 
named Berrembed, a weir 
has been constructed, which 
diverts the flow into the 
main canal. At the present 
time that canal is excavated 
nearly to the township of 
Griffith, 90 miles further on, 
and it will eventually ex- 
tend another 380 miles. 
Since the closing of the out- 
let tunnel through the dam 
in 1918, the flow of the 
Murrumbidgee has been 
regulated at the dam. Sufli- 
cient water has been passed 
through the sluices to pro- 
vide, with the unregulated 
discharge of the Tumut 
River and other affluent 
streams, a flow in the Mur- 
rumbidgee River sufficient 
to provide for irrigation 
requirements, and for the 
riparian interests. This is 
the principle which will be 
followed when the dam has 
been completed and _ the 
whole of the irrigation — 
areas are in full operation. - 
It is then estimated that 
the combined flow, partially 
regulated as above, will be 
sufficient to provide at 
Berrembed a continuous 
supply of 2,000 cubic feet 
per second, delivered into 
the main canal during the 
summer months, with a 
somewhat less quantity during the earlier and later months of the 
irrigating season, which usually extends from the beginning of September
