Frontier and pioneer life -- Australia -- Queensland
The Government have sunk a number of wells, while hundreds of flowing
bores that now stud the great western country have been put down by
private enterprise. The policy of the Government has been to determine
the area within which artesian water may be hopefully searched for, and
to provide water in arid country or on stock routes, and excellent
results have attended the carrying out of this policy. The Winton bore
is down in the lower cretaceous beds 4,010 feet, it gives a flow of
720,000 gallons of water a day, at a temperature of 192 degs.; the
surface level is 600 feet above the sea; it will take about £8,000 to
cover the total cost of sinking, etc. The Charleville bore has the
largest flow of any Government bore, giving 3,000,000 gallons in the
twenty-four hours, but some bores on Tinenburra, on the Warrego River,
give as much as 4,000,000 gallons. About 800 private bores have been
sunk in search of artesian water in the western area of Queensland; of
these 515 give a total output of 322 millions of gallons in the
twenty-four hours, and the total cost of them amounted to nearly
£2,000.000. This expenditure made within sixteen years, is creditable to
the energy and forethought of the western settlers. Some of the bores
are not overflowing, and the water is raised by pumping, though the
supply is inexhaustible. By the flow of water thus brought to the
surface, the devastating effects of the periodical droughts have been
minimised, and large areas have become available to profitable
occupation that previously were waste country. The flow of this artesian
water from the private and public bores is worth more to Queensland than
a river of gold. They have completely changed the face of the country,
and removed the anxiety of the stock owners towards the end of the
season, when all surface water (except the most permanent lagoons) has
dried up and formed mud traps to catch all weak stock that venture near
them. These tiny perforations of the earth's surface have helped to
solve the difficulty of settlement on the western lands, where we find
the rainfall diminishing as we go further west. As these little threads
of water find their way across the plains and form into small ponds in
the hollows, the wildfowl resort to them as if they were natural waters,
while the bulrushes (typha angustifolia), soon follow and grow in
masses, although these are only to be found round springs, and never in
permanent lagoons or rivers. Some curious features are connected with
the artesian water supply; sometimes the temperature is very high, that
of the Dagworth bore reaching 196 degrees, while the pressure of the
Thargomindah bore is over 230 lbs. to the square inch. The water supply
tapped is perhaps beyond calculation, and up to the present time there
is no indication of exhaustion.
