IRRIGATION, A SKETCH OF ITS HISTORY AND PRACTICE IN VARIOUS COUNTRIES
BY PATRICK HAMILTON, Commissioner of Immigration for Arizona Territory
The following papers, with one exception, first appeared in the Arizona "Gazette," and, at the request of many farmers and
fruit-growers, they are now presented in pamphlet form. The subject of irrigation has not received that attention from the
residents of the "dry belt" which its magnitude demands. Yet there is no industrial question of greater importance to the
people of Western America; for upon an intelligent mastery of the true principles underlying the control and application of
water to the thirsty soil must rest the future growth and prosperity of that region. This is especially true of Arizona, whose
grand agricultural possibilities are gradually becoming known and appreciated.
In this sketch I have aimed to present, in a condensed form, all available facts, with the hope that it may serve to dispel
some of the dense ignorance that prevails in Arizona on this subject. For much of the data in these papers, I am indebted
to Powell's "Lands of Arid Regions ;" the Reports of the State Engineers of California and Colorado; N.S.W., and the proceedings
of the Riverside Irrigation Convention.

IRRIGATION IN ARIZONA
Arizona is one of the oldest of irrigated countries. When the Spaniards explored the regions now embraced within this Territory
and New Mexico, they found this system of agriculture practiced by the Pueblo and other semi-civilized Indian tribes. But
the traces of irrigating canals in the valleys of the principal streams, would show that this method of cultivation was carried
on here centuries before Europeans set foot on the Western Hemisphere.
The Pimas are the earliest irrigators in the territory of whom we have any authentic account. When Coronado led his expedition
through Arizona, in 1540, these people were found farming the lands of the Gila valley by the aid of primitive irrigating
ditches, just as they do to-day. The communal system of land and water prevailed amongst them as it does now; and the centuries
which have since come and gone have brought no changes to the Pima nation. They still till the soil and gather the harvest
as their forefathers did, and as their descendents will, no doubt, continue to do, until the last of the race shall have been
gathered to the happy hunting grounds.
The Mission Fathers were the first to introduce a more perfect system of irrigation in the region now known as the Arizona.
The neophytes who gathered around their religious establishments in the valley of the Santa Cruz, were instructed by the pious
padres in the arts of tillage, and taught to build ditches and raise crops on the rich bottom lands of that stream. For years
the settlements on the Santa Cruz represented the efforts of agricultural effort in Arizona; and it was not until the Americans
established themselves in the valleys of the Salt and Gila Rivers that this method of farming was practiced to any extent
in the territory. Since that time, now nearly eighteen years ago, the irrigable area has been steadily enlarged, and within
the past year several important canal enterprises have been inaugurated.
The agricultural resources of the country, so long neglected, are attracting the attention of people abroad, and the question
of water supply is of the first importance to the new-comer. And in passing, it maybe remarked that our knowledge of this
matter, is most vague, indefinite, and altogether unreliable. It is nearly impossible to secure data in which any reliance
can be placed. Men who for years have practiced irrigation in this Territory seem to be incapable of giving intelligent answers
to any question relating to the business. They know they have plenty of water and the privilege of using it when they please,
but beyond this they have not cared to enquire. As a consequence, the facts relating to the irrigation problem in Arizona
are difficult to obtain. The information presented falls for short of what the writer sought; but repeated enquiries to farming
settlements, in different parts of the Territory, have failed to elicit a response.
CAPACITY AND COST OF CANALS
The Salt River Valley has the largest and most costly irrigating works which Arizona can show. The names of the leading waterways,
and the length of each is as follows:
Arizona Canal |
40 miles |
Grand Canal |
22 " |
Maricopa Canal |
14 " |
Salt River Valley Canal |
18 " |
San Francisco Canal |

18 " |
Mesa Canal |
9 " |
Utah Canal |
6 " |
Farmer's Canal |
5 " |
Total Length of Canals |
151 miles. |
There are a number of smaller ditches scattered over the valley not included in the above, which may increase the total length
to one hundred and sixty miles.
The cost of these canals is hard to determine. Aside from the first outlay for construction, there is to be considered the
yearly repairs for breakage of dams, enlargement of ditch, etc. The figures on some canals could not be obtained.

It is quite likely that these figures are much too low, and that the actual cost of the irrigation ditches in the valley will
not fall short of $800,000. The carrying capacity of the several canals, as nearly as can ascertained, is as follows:
Arizona Canal |
40,000 inches |
Grand Canal |
10,000 |
Salt River and Maricopa Canals |
6,000 |
San Francisco Canal |
4,000 |

Mesa Canal |
4,000 |
Utah Canal |
2,000 |
Farmer's Canal |
500 |
|
|
Total |
72,560 inches |
Of this volume of water little more than 25,000 inches is now being carried upon the land and utilized. The area reclaimed
in the valley by the various canals now constructed, is not easily ascertained, but the following approximate estimate will
not vary materially, from the actual figures:
Arizona Canal |
85,000 acres |
Grand Canal |
20,000 |
Maricopa Canal |
12,000 |
Salt River Valley Canal |
15,000 |

168,000 acres |
This is something like the area enclosed, and which could be watered by the present canals. It may be that some of these ditches
have not a carrying capacity at present, sufficient to irrigate the acreage they enclose, but all the land which naturally
lies under them, will, no doubt, yet to be reclaimed by their waters. Of this large acreage, it is believed that not over
40,000 or less than one-fourth of the whole, is under cultivation. Of the 400,000 acres of surveyed land in the Salt River
Valley, it is believed that 250,000 are susceptible of irrigation. When people learn to use water with that care and economy
that is practiced in scarcity makes it precious, there is hardly a doubt that this immense tract will be made productive.
At present, but little more than three fifths of it is enclosed by canals, and less than one-sixth is under cultivation.
The Pueblo Viejo Valley, on the upper Gila, is one of the richest tracts of agricultural land in the Territory. The following
ditches have constructed in that valley:
San Jose; |
seven miles long |
reclaims 2,000 acres |
cost $5,000. |
Montexuma; |
thirty miles long |
reclaims 5,000 acres |
cost $8,000. |
Sun Flower; |
three miles long |
reclaims 500 acres |
cost $2,500. |
Central |
eight miles long |
reclaims 5,000 acres |
cost $7,000. |
Smithville |
five miles long |
reclaims 3,000 acres |
cost $4,000. |
Nevada |
; three miles long |
reclaims 500 acres. |
McMurrin |
four miles long |
reclaims 600 acres. |
These ditches are on the south side of the Gila. On the north side of the river there are six, aggregating twenty-three miles
in length and reclaiming about 3,000 acres. Their total cost was near $12,000.
This shows the total length of irrigating ditches in the Pueblo Viejo to be sixty-six miles.

Of this area, not more than 12,000 acres are now under cultivation. The capacity of several canals was not given. The total
acreage of arrable land in the valley is nearly 40,000; so that less than half of it is enclosed.
The largest body of arrable land in Yavapai County was found in the Verde Valley. There are, besides, a number of small valleys
in the different parts of the country, where irrigation is practiced, but the area under cultivation is small, owing to the
limited water supply. Hon. John Davis, an old resident of the Verde, sends the following about irrigation in that locality:
Nine canals have been constructed, aggregating about 30 miles in length, and costing about $20,000. These canals supply water
to 2,500 acres - their united capacity being about 1,500 miner's inches.
No data in regard to the condition of irrigation in Pinal, Apache, Pima, or Yuma Counties, has been received. There are number
of canals in the Valley of Gila near Florence, and fully 10,000 acres are under cultivation in that neighborhood. On the Little
Colorado and its tributaries, in Apache County, it is estimated there are close on to 18,000 acres reclaimed, most of which
is under cultivation. In Pima County there is said to be 4,000 acres under the plow, and in the valley of the San Pedro, Cochise
County, about the same number. In Yuma County there is said to be 2,000 acres cultivated. Estimating the cost per acre for
reclamation in those counties at $4, which is a low figure, the outlay for canals is each would be as follows: Pinal, $40,000;
Apache, $72,000; Pima, $16,000; Cochise, $16,000; Yuma, $8,000. This would make the total cost of the irrigating works already
constructed in Arizona, over $1,000,000. The total length of all these waterways cannot be much less than 400 miles.
"DUTY" OF WATER
The "duty" of water in Arizona may be considered an unknown quantity. There is but little data relating to the question worthy
of any consideration. The loose and unreliable system of measurements which prevail, make any definite calculation almost
impossible. The practice, which very generally exists, of taking water at pleasure in such quantity may be desired, makes
the irrigator altogether indifferent to the matter of measuring it. While all the larger canals employ a zanjero, whose duty
is to make an equitable distribution according to the "right" of each cultivator, yet, so loosely is the business conducted,
that very often one man receives much more than he is entitled to, while other another receives much less. Throughout the
irrigated valleys of Territory, water is measured by the miner's inch, generally with a four-inch pressure. It has been shown
how inaccurate is this standard, and how variable are the results from it.
Taking the Salt River Valley as an example of the system of artificial cultivation which prevails in the Territory, we find
that all the principal canals are owned and managed by incorporated companies. With the exception of the Arizona Canals, all
those ditches were constructed by the co-operative efforts of the owners of the land, which has been reclaimed by their waters.
Some furnished teams and tools, other gave their labor, while a few contributed a money consideration. Stock was issued to
each, according to the amount of money or labor he gave to the construction. This was the origin of the system of "water rights"
which prevails throughout the Territory. The first cost of each "right" or share, was the amount of money or value of labor
which the owner contributed to the building of the work, but there has been a rapid increase in value. In all of these canals,
each share of stock represents a quantity of water suppose to be sufficient for the irrigation of a quarter of section of
land. This "right" is generally 80 miner's inches. The owner of a share of stock has privilege of drawing from the canal,
each season, the quantity of water which it represents by paying therefor a certain price per inch. If he does not wish to
use the water himself, he can sell his privilege, for the season, to whom he pleases. And, again, if this share of stock entitles
him to purchase 80 inches, and he finds that 60 inches is that all he requires, he can sell his right to the remaining 20
inches to whoever applies for it. If the outcome from the sale of water is not sufficient for the maintenance of the canal
and the pay of officers, an assessment is levied upon the stockholders to meet the deficiency; and if there should be a revenue
from sale of water to parties not holding shares, a dividend is declared. This is the plan that governs in the Salt River
Valley, the Maricopa, and the Grand Canals.
The quantity used per acre under these canals, varies from one-half to three-eighths of an inch, during the irrigating season,
Experienced irrigators find the latter quantity abundant to produce a crop. Here, as in all other irrigated regions, it is
found that continuous flooding for a number of years, increases the duty of water. Several farmers, south of Phoenix, do not
use more than one-quarter of an inch per acre for the production of a crop, and some get along with much less. In the vineyard
of Mr. John Montgomery, water is found at a depth of 12 feet below the surfaces; the roots of the plants have penetrated to
the moisture, and he has not irrigated his vines for two years. In the Tempe Canal, which is controlled by a private company,
each share-owner takes as much as he requires, and as often as he requires it - there being no measurement and no limit, except
the supply in the river. Yet, under this wasteful system, it is found that 60 to 80 inches is enough to produce a crop of
160 acres.
There is an extravagant use in water in the Pueblo Viejo Valley. In that locality water is divided into "irrigating streams,"
each "stream" containing one hundred any forty-four miner's inches, under a four-inch pressure. This body of water is used
to irrigate eighty acres during the season. This is perhaps, the most wasteful use of the fluid that any portion of the arid
region can show. In the Verde Valley, the duty of water is three-fours of an inch to the acre. It is acknowledged that crops
could be raised with much less, but as there is an abundance in the stream, each man takes as much as he pleases. The quantity
of water used per acre in the farming settlements of Pinal, Coshise, Apache, and Pima will range from one-half to one inch.
Wherever irrigation is practiced in the Territory there is waste and extravagance in the use of water. Ignorance and inexperience
in the application of it is, in most cases, the main cause. Where the careful cultivator and experienced irrigator finds three-eighths
of an inch per acre entirely sufficient, his neighbor, farming the same character of soil and raising the same kind of crops,
will not be satisfied with the less than an inch to the acre.
COST OF WATER
The cost of water to the Arizona irrigator is another difficult matter to determine. Water "rights" for the irrigation of
a quarter section of land in the Salt River Valley vary from $500 in the Grand, to $1,000 in the Arizona Canals. Having secured
a "right," the cultivator has then to pay as much, yearly for the water he requires. In the Grand Canal the price is $2.00
per inch, in the Maricopa about the same, and in the Salt River Valley Canal $1.75 per inch. Under the rules adopted by the
Arizona Canal Company, the farmer is taxed at the rate of $1.25 per acre, for every acre he cultivates yearly. It will be
seen that this system is radically different from that which prevails not only in Arizona but in nearly all of the irrigated
regions of the West. Under the plan adopted by this company, the water is wedded to the land, neither can be sold separately;
while in all the other incorporated canals in the valley the reserve prevails, and water shares pass from hand to hand like
any other commercial paper. The danger of the latter policy lies in the opportunity it presents for the control of the stock
by unscrupulous speculators.
The Arizona Canal Co. issues no stock to purchases of water, and consequently they have no voice in its management or control;
while in all other companies shareholders have a vote and a voice in the regulation of their affairs. Water owners in the
Tempe Canal, which is not incorporated, pay nothing, directly for the use of the water, but are liable to an assessment each
year for maintenance of works and pay of officers.
The waters of the canal which supplies Mesa City, are rented to the farmers at the rate of $30 per share per year-a share
being sufficient to irrigate thirty acres-making the cost one dollar an acre. In the distribution of water from the irrigating
canals of the Territory there is but one feature worthy of any commendation. That is the policy which has been adopted by
the Grand, Maricopa, and Salt River Valley Canals of selling water to those entitled to purchase, in such quantities as the
irrigator finds sufficient for the production of a crop. With a correct system of measurements and a careful supervision of
works, this method is a good one. It encourages the consumer to be economical in the use of water, knowing that he can sell
what portion of his "right" he does not use, to some one who wants it. It is the only just and sensible policy seems short-sighted.
The less water required to cultivate a tract of land, the more water rights the company will be able to dispose of, and the
larger the area that will be reclaimed.
TERRITORIAL LAWS
Arizona being one of the oldest irrigated regions of the western continent, a stranger would naturally expect to find here
a well-matured legal code regulating the control and distribution of its waters. In this he would be disappointed. The water
question is in as unsettled a condition here as in California; and while the Territory has thus far escaped the flood of litigation
which has swept over the Golden State, an increase of population and a greater demand for water gives warning that it may
not be so fortunate in the future. Our bill of rights declare that "all streams, lakes, and ponds are public property," and
that no one has the right to appropriate them exclusively to his own private use. The territorial statues declare that all
rivers, creeks, and streams of running water "are applicable to the purposes of irrigation and mining;" and the further declaration
is made that "all the inhabitants of the Territory who own or possess irrigable lands shall have the right to construct public
or private >acequias the gist of the Territorial law relating to irrigation. It merely recognizes the right of appropriation,
but makes no provision for the proper regulation of the same. Neither does it make any provision for the control, distribution,
measurement, or sale of the precious fluid. Individuals or corporations may appropriate and control large quantities of water,
but there is no legal supervision over their acts, nor any safeguards thrown around the consumer. There is nothing to prevent
criminal waste, nor is there any check to corporate extortion. And yet there is nothing which should be guarded more carefully
or poised more dearly. Arizona's mineral wealth has been called "the jewel of her sovereignty," but her rivers and streams
are the arteries through which courses her very life blood.
Priority of appropriation has been recognized by our Territorial courts, but where rights are so vaguely defined and appropriation
so unrestricted, there must be a lack of that feeling of security which should attach to the possession of water as well as
to land, in a land where irrigation is a necessity. The greatest evil that can befall such a country is an insecure and undetermined
title to water. In arid regions like Arizona, the values are entirely in the water, without it the soil must always remain
a desert. People seeking homes here realize this fact, and desire, first of all, to know that the supply is abundant, and
that the titles are secure. Is it not that of primary importance to every one who has the interest of the Territory at heart
to have this matter adjusted on a basis just and equitable to all?
The necessity for wholesome legislative control over the wholesale appropriation of water is apparent to everyone. Large quantities
are being claimed by corporations, and in a short time every inch, available for agriculture, will be appropriated. The possession
of the water by those companies, virtually, gives them control of the land. Now, while such reclamation enterprises are of
great benefit to the Territory, and worthy of all legitimate encouragement, it is yet the duty of the people of Arizona to
see that it's public waters are not controlled by monopolies.
The large canals now being constructed in the valleys of the Gila, as well as the Arizona Canal, in the Salt River Valley,
are speculative enterprises, out of which their projectors expect to take money. This is proper and entirely legitimate, and
those who have engaged in such ventures deserve to be well remunerated. But while favoring every public enterprise of this
character, it is the duty of the people to see to it that such corporations do not misuse the powers which the control of
large quantities of water naturally gives them. The primary principle that water is a gift from Nature, and as necessary to
man's existence as the air he breathes, should not be lost sight of. For the construction of irrigation works and the bringing
of water to the cultivator, there should be given a fair and liberal compensation. This is a proposition that will not be
disputed. Neither can the right of the people to prevent unjust and extortionate charges, be denied. If there is no check
upon the actions of large canal companies, the harmer and fruitgrower must rely entirely their sense of justice. The people
of California and Colorado, realizing this danger, have made legal provisions which effectually prevent extortion by water
companies.
The loose system of measurements should be done away with, and wastage should be prevented. In a country like ours where every
inch of water is precious, reckless waste ought to be made a criminal offence. The present system of claiming thousands of
inches of water, which are not used, is untenable both in law and equity. No individual or corporation has a right to any
more water than he or they actually use. This is the only true policy, and is recognized in all irrigating countries where
the waters are under legislative control.
The waters of all rivers and streams in the Territory which are utilized for irrigation, should be accurately measured, and
the quantity available at all seasons should be known. This will not only be of great benefit to the irrigator, but do away
with the present system of unchecked appropriation. When the volume of water in a stream was known, and the share of each
appropriator definitely determined, it would assure to the farmer a certainty that the water company would be able to deliver
the quantity he contracted for.
Irrigation to Arizona is what the life blood is to man, or the piston rod to the stream engine. The just and equitable control
and distribution of the poor waters of the Territory assure to our fertile valleys a large and permanent population and a
prosperous future. It is a vital question to our people, and one which heretofore has received but little consideration.
Yet it is not too much to say that the corner stone of Arizona's prosperity rests upon it. How important, then, is it to the
general welfare that our irrigation system should be upon a secure foundation of equity and justice preserving for all their
rights in one of the most precious gifts of Nature, and doing no wrong to vested interests.
It for those directly interested, and with the light of experience to guide them, to decide how this important problem shall
be solved. It is a matter of deserving more thought and attention than has yet been bestowed upon it. Its satisfactory solution
is only a matter of time; but it would be well if the people of these valleys would consider the question from a broader and
more liberal standpoint than that of mere self-interest. It is admitted that law of some kind is a necessity, but what particular
laws a people should have on any particular subject, is for the people themselves to decide. In conclusion, it maybe said
that these papers have been collated and published with the hope that they may prove of some benefit to the Arizona farmer.
If the data contained therein shall help him to a better understanding of the irrigation question, and if a knowledge of the
laws and regulations governing it in other countries shall assist him to deal intelligently with it here at home, the effort
will not have been in vain.
