Drought.
A drought is a prolonged, abnormally dry period when there is not enough water for the users normal needs.
Drought is not simply low rainfall; if it was, much of inland Australia would be in almost perpetual drought. Because people use water in so many different ways, there is no universal definition of drought.

Meteorologists monitor the extent and severity of drought in terms of rainfall deficiencies. Agriculturalists rate the impact on primary industries, hydrologists compare ground water levels, and sociologists define it on social expectations and perceptions.

1921:
Australia denies the image as being drought-prone.

Politicians and bureaucrats were eager to deny the image of Australia as drought-prone, lest this deter immigrants.
H. S. Gullett, the Commonwealth Superintendent of Immigration, was quoted as saying:
“Many thousands of Australians go abroad every year on business or pleasure.
The Commonwealth Immigration Office appeals to every one of them to embark with the resolve that he will on all possible occasions speak well of Australia.
Let none of them speak evil. Such words as 'drought' should be thrown overboard as the vessels put out to sea.”
(Sydney Morning Herald, 6 June 1921. )

1990:
Drought is part of the natural variability of the Australian climate.

" The 1990s saw formal Government acknowledgement that drought is part of the natural variability of the Australian climate, with drought relief for farmers and agricultural communities being restricted to times of so-called “exceptional circumstances”. In other words, the agricultural sector was expected to cope with the occasional drought, and relief would be available only for droughts of unusual length or severity."

2008:
Australia bans word 'drought' as too upsetting for farmers

The word "drought" makes farmers feel depressed and should be replaced with "dryness", a panel of Australian government experts has said.

The Murray river - Australia's longest river 2375 kilometres.(4)

Did the Murray river , Australia's longest river , ever stop flowing ?
Murray-Darling Basin Commission water resources manager Andrew Close said if the Murray still had its natural flow, it would have probably stopped flowing this year ( 2006 ) , as it did in 1850 , 1902 - during the Federation drought when it stopped flowing for about 6 months , 1914, 1915 and 1923, while the Darling River dries up more frequently.
  Source:  The Australian November 11, 2006 12:00am
"...if all dams and weirs did not exist and no water was extracted from the system....the Murray would have ceased flowing during the more severe droughts, including the current dry period " ( 2008 ).
" In the last couple of years a continuous flow along the length of the Murray has been maintained by drawing upon water stored upstream, particularly in Hume and Dartmouth Reservoirs when other tributary inflows are low. "  Source: MDBC Murray System Drought Update No. 15 – September 2008

In Melbourne, on the 8 February 1983 the temperature rose quickly as the north wind strengthened, and by 2:35pm it had reached 43.2°C.
A short time later, a spectacular reddish-brown cloud could be seen advancing on the city, reaching Melbourne just before 3pm.
It was accompanied by a rapid temperature drop, and a squally wind change strong enough to uproot trees and unroof about 50 houses.
Visibility plunged to 100 metres, and according to witnesses “everything went black” as the storm struck.
The worst of the dust-storm was over by 4pm, when the wind-speed dropped rapidly.

Historical perspective of a drought prone Australia.

Australia is prone to drought because of its geographic location.
Much of Australia lies in a latitude belt that is under the influence of an atmospheric phenomenon known as the subtropical high.
Just outside of the tropics in each hemisphere lies a swath of the globe where air frequently sinks toward the Earth’s surface from higher in the atmosphere.
The air warms and dries as it sinks, creating semi-permanent zones of high air pressure at the surface.
These subtropical highs are areas of stable, warm, and dry air that favour clear skies and little rainfall.
(In the Northern Hemisphere, several large deserts, including the Sahara, reside in the latitudes of the subtropical high.).

Persistent high pressure over most of Australia leads to low and often erratic rainfall. Drought tends to occur when the high pressure systems are more extensive than usual, excluding rain-bearing systems for lengthy periods of time.(5)



The Indian Ocean Dipole

A phenomenon known as the Indian Ocean Dipole (IOD) - a variable and irregular cycle of warming and cooling of ocean water - dictates whether moisture-bearing winds are carried across the southern half of Australia.
When the IOD is in its negative phase, a pattern occurs with cool Indian Ocean water west of Australia and warm Timor Sea water to the north. This generates winds that pick up moisture from the ocean and then sweep down towards southern Australia to deliver wet conditions.
In its positive phase, the pattern of ocean temperatures is reversed, weakening the winds and reducing the amount of moisture picked up and transported across Australia. So the south-east misses out on its usual quota of rain.
The IOD is commonly measured by an index that is the difference between sea surface temperature (SST) in the western (50°E to 70°E and 10°S to 10°N) and eastern (90°E to 110°E and 10°S to 0°S) equatorial Indian Ocean. The index is called the Dipole Mode Index (DMI).(7)

"We have shown that the state of the Indian Ocean is highly important for rainfall and droughts in south-east Australia. More than the variability associated with the El Nino/La Nina cycle in the Pacific Ocean, the Indian Ocean Dipole is the key factor for driving major south-east Australian droughts over the past 120 years (8)."


The IOD has been in its positive or neutral phase since 1992, the longest period of its kind since records began in the late 19th Century

Many drought episodes in the eastern and northern part of the Australia are linked to El Niño episodes.

Reports of Drought by our Early Settlers.


The Brisbane Courier Friday 11 October 1889

THE PREDICTED DROUGHT. Australian weather statistics 1782 - 1889.
" In order to throw some additional light on the above question, I will furnish a few condensed Australian weather statistics of the last 107 years, and if anyone can found a positive forecast on them he is welcome to do so ; all that I can see in them is the simple fact that floods and droughts alternate out here with "lucid intervals" of ordinary settled and moderately wet or dry weather.

Captain Cook in 1770 says little about the weather. Dampier in 1690 or thereabouts was equally silent.
Captain Matthew Flinders reports drought and bush fires from 1782 to 1792.
There was a great drought in 1797 for 100 miles round where Melbourne now stands ; 1799 to 1806 were very wet years, and in 1806 the floods culminated by a rise of 101 ft. at Windsor, on the Hawkesbury River.
The crops were destroyed, wheat rose to 80s. a bushel, and a famine prevailed.

The excessive rain kept on till 1810, but 1811 cut it short, and was so dry that water was worth 8d. per bucketful in Sydney.
This drought was sharp but short, and there was plenty of increasing rain for years afterwards, till in 1820 the Hunter River rose 37ft.

Ten years now elapsed without any more floods, and it was so dry from 1826 to 1829 that water at last became worth 4d. a gallon in Sydney. 1830 saw the first flood for ten years.

Ordinary weather followed till 1837, but 1838 and 1839 saw the champion drought of the century. Stock were all but exterminated. The Murrumbidgee is a great river, 150ft. wide, 60ft. deep, and overflows its banks, like the Nile, when the head snows melt, for five miles on each side to a depth of 3ft. This gives a volume of water equal to a river of 1450 ft. wide and 120 ft. deep, and besides this it fills a group of lakes each from seven to eighteen miles in diameter.
Yet this great river dried up so thoroughly in 1839 that the fish died and putrefied at the bottom of it.

I make no comments on what such a drought now would do to Queensland, and I am at present only going for dry facts and bald statistics.
1841 broke up this drought with the champion flood of Queensland; the Bremer River rose 70ft., and the Brisbane bar not being then dredged, there was no quick "get away" for the water, and it filled the lower story of the commissariat stores here, and Ipswich was very short of rations for some days.

Moderate rain carried the colony of Now South Wales (then the only one) on till 1849, when dry weather began and lasted till May, 1851.

The scattered bush fires of Victoria got " boxed" into one mighty whole on 6th February, 1851 (" Black Thursday "), before a southerly hurricane which sent smoke and leaves across Bass Straits.

1852 brought a flood that swept Gundagai away and drowned the inhabitants ; 1853 saw great overflows of the Lachlan, Murrumbidgee, and Darling rivers, but not from local rain ; 1854 was dry; 1855 and 1856, ordinary weather; 1857 was a flood year, with three months ceaseless rain from February to May.
Settled weather lasted till 1863, which, with 1864, both gave heavy flood. The weather settled again till 1873 (bar a small drought up North in 1866), which, with 1875, was very wet, and gave a flood each.

Settled weather again carne, with a small local flood in 1879-80 ; 1882 very wet: 1883 to 1886 very dry; 1887 very wet; 1888 very dry; 1889 moderately wet.

Here we have 107 years of statistics, and who can discern from them the rule that guides the weather ? A matter which enters so largely into our health and comfort, happiness and prosperity, that I hope to be excused for thus dwelling upon it. ......

Reports of Drought by our Early Settlers.

Governor Arthur Phillip 1791
Governor Arthur Phillip wrote the following to the Colonial Secretary, the Right Honourable W. W. Grenville on 4 March 1791:

The Tank Stream Sydney (10)

"From June until the present time so little rain has fallen that most of the runs of water in the different parts of the harbour have been dried up for several months, and the run which supplies this settlement is greatly reduced, but still sufficient for all culinary purposes... I do not think it probable that so dry a season often occurs. Our crops of corn have suffered greatly from the dry weather."

On 5 November 1791, the governor of this colony, Arthur Phillip, reported that the normally perennial 'Tank Stream' river flowing into Sydney Harbour had been dry for "some months".
It did not flow again until 1794. Phillip marks the start of the droughts in July 1790; no rain had fallen by August 1791   **

During the drought in 1814 Governor Macquarie had to import food to avoid what he called:
"the heavy calamity of very great scarcity, both of animal feed and of grain, if not in an actual famine."

Drought related excerpts from local Newspapers.  1803 - 1839


1803
The late drought has been severely felt in all parts of the Colony, and has been attended with much loss to the gardener. In fact, vegetation was almost at a stand, and a great part of the feed, for want of rain, perished in the ground. The crop of potatoes has turned out very indifferently ; and the maize, but for the late seasonable rain, would have been equally unpromising :
We are happy to state however, that in all parts of the Colony, so manifest a change has taken place in the latter, as to assure the grower of an abundant crop.
The Sydney Gazette and New South Wales Advertiser   Sunday 29 May 1803

1811   March
The long-prevailing drought has destroyed every hope of a maize crop, which is now unfortunately past recovery. A scarcity of water has also been the consequence, scarcely ever, before witnessed.

In Sydney the 'Tanks' have been, several weeks empty, and those who, were in want of water are obliged to collect it from small cavities in the spring course above the 'Tanks', which has afterwards been sold at from four-pence to six-pence per pail. The month of March however has commenced and rains are of course to be expected.
The Sydney Gazette and New South Wales Advertiser  Saturday 2 March 1811

1811   October
The long succession of dry weather at the present season has heretofore been unexampled, and the field and garden languish for the want of rain
The last refreshing shower with which Divine Providence was pleased to favour us was upon the 27th of August : it was very general, and gratefully acceptable throughout the various settlements, its continuance was about 24 hours: since which period however, we have scarcely had one visiting shower.

From this, great cause the growing wheat has in situations naturally dry received much injury; while in moister grounds, that have the advantage of a humid atmosphere the appearance is far more promising.
The produce of the late sown fields depends much upon the weather for a few weeks to come, the farmers hope rain without which they can form no expectation of the latter crop, nor save the season for planting maize, some former disappointments in the crops of which have been felt severely, as the rapid decline of stock was among the certain consequences.

From the best information we can collect, so intense a drought at this time of the year has not been witnessed since the year 1789, when the new colonists suffered a parching thirst; for several months, the springs from which they had been before supplied either failing totally, or yielding scarcely a sufficiency to support nature, numbers of flying foxes and squirrels, parrots, and birds of all the various species, flocked from the interior to the sea-coast, and perished as they flew.

A visitation of so dreadful a calamity in the present state of the Colony would be incalculably severe, owing to the numerous, and in many instances extensive herds that must participate a disaster; from which it is our duty fervently to pray that Providence may ,defend those creatures that instinctively lay claim to her benign consideration and protection.

1815
The GOVERNOR was highly gratified by the appearance of the country, which there began to exhibit an open and extensive view of gently rising grounds and fertile plains.- Judging from the height of the banks, and its general width, the Campbell River must be on some occasions of very considerable magnitude ; but the extraordinary drought which has apparently prevailed on the western side of the Mountains, equally as throughout this Colony for the last three years, has reduced this River so much that it may be more properly called a Chain of Pools than a running stream at the present time.
The Sydney Gazette and New South Wales Advertiser   Saturday 10 June 1815

1815
The repeated Droughts for the last three Seasons induce the Governor to recommend to the Settlers to sink large Reservoirs or Tanks for the Reception of the occasional Rains, whereby he is assured that much of the Injury now sustained by the Cattle for Want of Water would be happily avoided ; and he also strongly advises them to make a certain Proportion of Hay annually for the Use of their Cattle, when by Means of the Droughts the grass becomes insufficient for the Animals they have to provide for......
The Sydney Gazette and New South Wales Advertiser  Saturday 9 December 1815

1820
The present dry reason of the year being indicative of an approaching long drought, which will be much felt throughout the town of Sydney, we presume it would be advisable, as much for the sake of decency as cleanliness, to pay a little if not due regard to the General Orders in existence relative to the preservation from all filth and impurity of that valuable and serviceable reservoir the Tanks.

With much pain we have lately observed individuals washing themselves in this stream of water, particularly in that part that runs central from King street, because that spot is almost secluded from every eye, that of curiosity excepted.
In former times the punishment tor this offence, it may be recollected, was summarily severe; and, as it is likely the Government and General Orders, bearing date the l5th September, 1810, and 11th August, 1811, are not known by some of the present inhabitants of the Colony, we embrace this opportunity of once more giving them publicity, trusting it may be productive of a prevention of such filthy and prohibited practices in future:
The Sydney Gazette and New South Wales Advertiser  Saturday 28 October 1820

1822
The other day a professional Gentleman, in Sydney, was induced to dig for some moist soil, in order to attempt the preservation of a few choice and valuable plants. After much labour he got as low as 20 feet ; and, at that depth, the earth was found to be in as heated a state as that within only a few inches of the surface.

The present month of February makes the fourth month of continued drought this season. All pretty well know that the whole of the wheat is safely in ; but the maize is in a terrible condition. That sown in and about Windsor, and its vicinity, is apparently very fine; but, upon close inspection, turns out to be mostly all stalk and leaves, hardly any cob.
The Sydney Gazette and New South Wales Advertiser   Friday 8 February 1822

1824
The want of maize is very much felt at Hobart Town just now.
It is to be regretted that the climate of that fine Colony is in congenial to the growth of an article so absolutely necessary for animal and other uses.
What makes the present scarcity of that article the more sensibly experienced, is the circumstance of the grass being destroyed by fire and drought for miles and miles around the most luxuriant part of the Country. Five months, we believe, have our neighbours been without rain. It affords us much satisfaction to be able to export some of our superabundant maize in this time of need.
The Sydney Gazette and New South Wales Advertiser  Thursday 3 June 1824

1828  A plea for drought assistance
Many of the poorer order of settlers, on , the Banks of the Hawkesbury, as well as in various other parts of the Country, the Public will grieve to learn, are in a state of utter destitution, which calamity has been induced by the continuance of that drought with which it has ple??ed Providence to visit this otherwise highly favoured land to an unprecedented extent.

From an authentic source we have been informed that a gentleman last week visited a settler's family in the neighbourhood of Windsor, consisting of himself , wife, and five children, who had scarcely had anything to wear, nothing in the world lo eat, and whose prospects for the year to come had all withered away from the effects of the drought, as at the usual time of harvest the poor man would have no crop to reap.

This is a melancholy picture, but it unfortunately happens only to be one instance out of numbers, we fear, that might he adduced.
Are those people, then, to whom the Colonists are so deeply indebted, to be allowed to perish of want ? Are we to suffer them to experience the sad effects of an extraordinary drought, when it is in our power, if only blessed with the inclination, to mitigate their calamities ?

Several friends of humanity have already requested us to open a list at the Gazette Office for the purpose of receiving subscriptions in aid of the poor settlers and their families, and some have even gone far as to subscribe their benefactions of £5.

AGRICULTURAL AND HORTICULTURAL SOCIETY OF NEW SOUTH WALES. ADDRESS OF THE PRESIDENT. (concluded)
The great drought, Gentlemen, The drought of three and a half years duration, which has happily passed away, in its effects killed more forest trees, and rent asunder the surface of the earth to a greater extent than has been witnessed, at any former period, by our oldest Colonists.

Hence we may hope, that the present generation will escape the witnessing of such another visitation. But, notwithstanding the scorching severity of the drought, the farmers reaped such a variety of crops, though scanty, and some of them impoverished in quality, still in such quantity, that if they bad been frugally used, would have been sufficient to keep tho population from starving.

1838
DROUGHT IN NEW SOUTH WALES.
By the Sydney papers to the 27th October, we observe that his Excellency -Sir George Gipps had appointed Friday, 2d November, to be observed as a day of fasting and humiliation throughout New South Wales, on account of the calamitous drought with which that territory has been afflicted.

While we deeply regret to perceive by the accounts from the interior that the losses of cattle and sheep, occasioned by the absence of rain, had been very great, still it ought to be a matter of lasting thankfulness to the Southern Australian, that while the regions to the eastward, lying in the same parallel of latitude, have suffered so severely from drought, rains have fallen with their accustomed regularity in our more favoured districts, and that, in fact, judging from the richness of the herbage, the size and foliage of the trees, there is every reason to believe that the periodical tracts of dry weather to which the other colonies are subject are altogether unknown in South Australia.

It is true that during the present season considerably less rain has fallen since May last than for the same period in the preceding year ; but we have had our regular showers at change and full moon in sufficient abundance for all agricultural or pastoral purposes.
The lambing season was most propitious, and several experienced shepherds have assured us that neither in New South Wales nor Van Diemen's Land, in the most favourable seasons, has the produce been more great, nor the condition of either the lambs or ewes so surprising. During the last three months rain has frequently fallen for four or five days in succession ; and we have every ground for expressing our confidence that our farmers will never be doomed to see their half ripened grain bleaching and withering for want of timely moisture, or their stock dying from the same cause on the plains.

It cannot be many years ere the proprietors to the west and northward of the mountains will discover it to be their interest to watch a favourable season, and, forsaking the poor and unproductive tracts of New South Wales, bring their flocks and herds to increase and multiply in the fertile, well watered, and far extending plains and valleys of South Australia.
South Australian Gazette  November 17, 1839

1839
The Drought.--A gentleman, who has just received intelligence from the district about the Murrumbidgee, yesterday informed us, that he had been informed that the waters of that river have decreased so much lately, in consequence of the drought, that in many places the water holes are dry, and fish weighing from thirty to forty pounds may be seen lying in a putrid state in the bed of the river.
The Sydney Gazette and New South Wales Advertiser   Saturday 9 March 1839

1839  The Drought.
The drought still continues, and the Colonists have before them every prospect of a famine or something very closely approximating to it.

From all parts of the country we have the same disheartening accounts. In most places the crops have entirely failed ; in some few, about half a crop has been realized.
In all quarters the sides of the road are said to be literally strewed with the carcasses of bullocks, which have perished for want of sustenance.

Under such circumstances it is, we think, worthy the serious consideration of the Government whether another day of fasting should not be set apart, to allow the people additional opportunity to humiliate themselves before the Lord in acknowledgement of their sins, and to pray that the curse which threatens to overwhelm the land may be averted.
The Sydney Gazette and New South Wales Advertiser   Thursday 14 March 1839

1839  The Drought.   YASS.
Extract of a letter from eighty miles south-west of Yass, dated April 10th :
Messrs. Hardy, Campbell, Sturt, and Stein, started on Wednesday last for South Australia, with a large herd of sheep and cattle. We find a shower of rain yester day, and it is now threatening heavily for more, and I hope it may soon fall, or I do not know what is to become of us many persons have been compelled to leave their homes for want of water; in fact, in this part of the country, starvation is staring every one in the face ;

I do not know how soon I shall have to " flee into the wilderness" in search of pasturage and water for our sheep and cattle. ..... Several of our neighbour's sheep are dying, not from disease, but want of sustenance ; grass there is scarcely any ; the face of the country is like a barren waste, the roots of the herbage seem almost destroyed from the long continued drought.

I hope, however, to give you a more flattering account in my next letter.
I understand the Blacks have been killing cattle on the Murray.
I believe Mr. Jobbins has suffered considerably.
The Sydney Gazette and New South Wales Advertiser   Thursday 25 April 1839



Our predecessors have recorded the climatic conditions endured during their exploration of Australia and in the new settlements.

Charles Sturt  1826
The year 1826 was remarkable for the commencement of one of those fearful droughts to which we have reason to believe the climate of New South Wales is periodically subject.
It continued during the two following years with unabated severity.
The surface of the earth became so parched up that minor vegetation ceased upon it.
Culinary herbs were raised with difficulty, and crops failed even in the most favourable situations.
Settlers drove their flocks and herds to distant tracts for pasture and water, neither remaining for them in the located districts. The interior suffered equally with the coast, and men, at length, began to despond under so alarming a visitation.
It almost appeared as if the Australian sky were never again to be traversed by a cloud.

But, however severe for the colony the seasons had proved, or were likely to prove, it was borne in mind at this critical moment, that the wet and swampy state of the interior had alone prevented Mr. Oxley from penetrating further into it, in 1818.




Charles Sturt  1826
The most serious disadvantages under which the colony of New South Wales labours, is in the drought to which it is periodically subject.
Its climate may be said to be too dry; in other respects it is one of the most delightful under heaven; and experience of the certainty of the recurrence of the trying seasons to which I allude, should teach men to provide against their effects.
Those seasons, during which no rain falls, appear, from the observations of former writers, to occur every   ten or twelve years;  and it is somewhat singular that no cause has been assigned for such periodical visitations.

Whether the state of the interior has anything to do with them, and whether the wet or dry condition of the marshes at all regulate the seasons, is a question upon which I will not venture to give my decisive opinion.
But most assuredly, when the interior is dry, the seasons are dry, and vice versa.
Indeed, not only is this the case, but rains, from excessive duration in the first year after a drought, decrease gradually year after year, until they wholly cease for a time.

It seems not improbable, therefore, that the state of the interior does, in some measure, regulate the fall of rain upon the eastern ranges, which appears to decrease in quantity yearly as the marshes become exhausted, and cease altogether, when they no longer contain any water.
A drought will naturally follow until such time as the air becomes surcharged with clouds or vapour from the ocean, which being no longer able to sustain their own weight, descend upon the mountains, and being conveyed by hundreds of streams into the western lowlands, again fill the marshes, and cause the recurrence of regular seasons.

But, it appears to me, it is not in the height and character of its hilly regions, that we are to look for the causes why so few living streams issue from them. The true cause, I apprehend, lies in its climate, in its seldom experiencing other than partial rains, and in its being subject to severe and long continued droughts

I joined the party encamped at Buree on the 13th of December, having rode there from Sydney in four and a half days, and on the following Monday, 15th of December, 1845, I put it in motion towards the interior.
The Exploring party now consisted of the following persons:— Sir T. L. Mitchell, Kt., Surveyor General, Chief of the Expedition.....
The very grass seemed parched and useless. I never saw vegetation so checked by drought.
A longer continuance was likely to kill all the trees, and convert the country into open downs.

An' the burnin' heat that dazzles as it dances on the sand;
When the sun-baked clay an' gravel paves for miles the burnin' creeks,
An' at ev'ry step yer travel there a rottin' carcase reeks…”
(from The Song of Old Joe Swallow, Henry Lawson).

Lack of water is a problem that dates back to time immemorial for Australia, the world's driest land. If Australia's total annual run-off was spread evenly over the continent, the water depth would be a mere three centimetres.

Down the length of the eastern side of the continent, most of the water run-off from the Great Dividing Range flows eastwards into the Pacific Ocean and Tasman Sea, leaving the vast tracts of land on the western side of he ranges dry and prone to lasting drought. Evaporation in the hinterland is high and in dry seasons many tributaries to the main inland rivers, the Murray, Murrumbidgee, Lachlan and Darling become little more than chains of waterholes.

Time and again lack of water almost wreaked a cruel end to the early settlement of eastern Australia. In the years 1813-15 it was drought and the spectre of famine which added urgency to efforts to find a way over the Blue Mountains from the Sydney area.

Widespread drought struck again from 1824 to 1829, withering the newly discovered plains country. Crops burned, stock died and despite their familiarity with the land's natural resources, many Aboriginals were also reported to have perished through starvation. The familiar visitation of disaster struck again from 1837 to 1840 and even the snow-fed Murrumbidgee was dry in places, allowing settlers in some districts to run horse races on its bed. In 1843 good sheep were selling for three pence a head. The list of bankruptcies grew longer daily. The Bank of Australia failed. James Tyson, the king of the squatters, sold one run for a tot of rum and a second for twelve pounds which he never bothered to collect.

The infant industry resorted to the desperate expedient of boiling down sheep for tallow. The average sheep yielded twelve to fifteen pounds of tallow and tallow was worth five cents a pound -- at least for a while. By the end of 1844 more than two hundred thousand sheep had been boiled down and tallow prices began to fall.

Drought struck again in the late forties and for more than a decade from 1861 to 1870. Some graziers built dams on creeks and guarded them with armed men against reprisals from aggrieved landowners further downstream. In a dry season in 1858 parties of men destroyed or damaged more than twenty-five dams on the Yanko Creek, which runs between the Murrumbidgee and Murray Rivers.

Still the droughts continued, bringing pain and despair. Rainless seasons continued to strike randomly through to 1878, almost wiping out whole pockets of the sheep and wool industry.

Then between 1895-1903 the so-called 'Federation drought' occurred.
The poet Henry Lawson has , avidly described the dire circumstances and plight of the farmer. His consternations were published in the newspaper " The Worker" in 1900 .

It appears from the writings of our pioneers that drought in Australia is a natural phenomenon that has to be endured by its inhabitants .

Australia's Longest Drought  1958 to 1968

Most areas of Australia were drought-affected for long periods between 1958-1968.
It was the longest drought in arid central Australia from 1958-67. Australia-wide, during its last two years alone (1967-1968) there was a 40% drop in the wheat harvest, a loss of 20 million sheep, and a decrease of farm income of up to $500m.
Event Start Date 01/01/1958    Event End Date 09/01/1968
Duration of Event   3896  days
Five million people were affected and a total loss of livestock was 40 million




 
Australian Drought Records

METEOROLOGY OF AUSTRALIA COMMONWEALTH BUREAU OF METEOROLOGY 1913
" ....the information for previous years being rather too scanty for any adequate review of their peculiarities, the principal drought years affecting the inland areas of South Australia, Victoria, and New South Wales, were 1881, 1884, 1885, 1888, 1895, 1896, 1897, 1899, 1902, 1907, and 1911.

In considering drought years, attention is directed rather to the failure of the rains during the critical periods for grass and crops, which may be taken as extending from 1st April to 31st October. The small annual rain totals for all but one of these constituted them drought years in any case, the exception, and a very remarkable one, being 1911, which, if the total rainfall alone is considered, stands out as one of the wettest years on record for Victoria, owing to two tremendous rain- falls in February and March. From July onward it was extremely dry, as were also the first five months of 1912. The years 1884 and 1885 were not universally bad, the former being very dry only in the eastern States, and the latter in South Australia.  " (6)

In the late 1930's and 1940's major droughts affected most of Australia.  Nearly 30 million sheep died between 1942 and 1945.

Since the 1860s there have been 10 major Australian droughts.
Some of these major droughts could be described as periods consisting of a series of dry spells of various lengths, overlapping in time and space, and totalling up to about a decade.

The drought periods of 1895–1903 (the so-called ‘Federation drought’), 1958–68, 1982–83 and 1991–95 were the most devastating in terms of their extent and effects on primary production.
The latter drought resulted in a possible $5b cost to Australia’s economy, and $590m in drought relief by the Commonwealth Government.

The remaining major droughts occurred in 1864–66 (and 1868), 1880–86, 1888, 1911–16, 1918–20 and 1939–45. In this same period, several droughts of lesser severity caused significant losses over large areas of some states. They occurred in 1922–23 and 1926–29, 1933–38, 1946–49, 1951–52, 1970–72, 1976 and 1997–2000.

Tasmania 2000
In March 2000, Central Highlands farmers said the worst drought since World War II was pushing them to the brink of despair. Some farmers believed their stock could be halved by the end of winter as the region endured its third consecutive year of drought.

Weather bureau figures showed that from October 1996 to almost mid-2001, the central and eastern region and the north-west of the State had experienced serious to severe rainfall deficiencies. From July to December 1999 almost all of the State experienced below normal rainfall levels and in parts of the South-East rainfall was the lowest on record.

The Tasmanian Department of Primary Industry, Water and Environment estimated that the drought had caused overall losses to the rural sector of sector of $50m from 1997 to 2000 with approximately $10 in 1997-98, $15m in 1998-99 and $25m in 1999-2000. (Another $10m was allowed for the remaining months of drought).

West Australia  2000
Not since the outbreak in WWI in 1914 had there been a drought so devastating in the eastern and northern wheatbelt.
A visit to the wheatbelt by the Minister of Agriculture in early July revealed an emerging tragedy in WA. The Minister said the drought was a tragedy of an enormous scale affecting one third of the Wheatbelt. He described the situation as "horrendous" and "sobering", a huge problem.

The Lakes District is at the heart of the worst affected area having recorded the lowest January to June rainfall on record. It was estimated only 70 per cent of crops had been planted and of those, about 50 per cent have germinated, with Western Australia facing a loss of up to $3 billion in total grain and livestock losses.
WA Agriculture minister Kim Chance estimated the drought will potentially cost the state $3 billion in livestock and cropping losses, depending on rainfall.

The 2002–03 Drought
While not quite as dry over most of eastern Australia as those of 1901–02 or 1982–83, was particularly severe in its impacts for two reasons.
First, it was accompanied by record high average maximum temperatures and, consequently, increased evaporation in many areas.
Secondly, it affected virtually the entire continent.
During earlier droughts the effects over Western Australia were more limited or non-existent.

The direct effect of the 2002–03 drought on agricultural production is that it had a downward impact on gross domestic product growth of almost one percentage point between 2001–02 and 2002–03 (see the article in the National Accounts chapter in Year Book Australia 2005).

Other notable droughts on the 1–2 year timescale include those of 1888, 1914, 1919–20, 1940–41, 1944, 1946, 1965, 1967 and 1972.

2002-06 Eastern and southern Australia is once again experiencing widespread drought, with agricultural income in 2006-07 expected to be at the lowest level since 1994-95.

Latest Drought Updates.

September 18, 2008
For large parts of southern and eastern Australia, dry conditions have persisted since October 1996, a total of almost 12 years.
During the last 7 years in particular, the Murray-Darling Basin has experienced severe rainfall deficiencies, and from September 2001 to August 2008 was the 2nd driest seven-year period
(the driest was from 1939 to 1946).

July 6, 2008
A joint assessment by the Bureau of Meteorology and the CSIRO, which found that what are now considered to be one in 25 year climate events could become as frequent as once every one to two years.
In particular, the study found exceptionally high temperatures would occur almost yearly, while low rainfall would almost double in frequency from current figures.




Yearly Rain Totals for location 5 km west of Romsey,
