John Wesley Powell served as the director of the United States Geological Survey from 1881–1894. This photograph dates from early in his term.

Wallace Stegner (1987): “The West is defined, that is, by inadequate rainfall. … We can’t create water or increase the supply. We can only hold back and redistribute what there is.”

In the 19th century, as settlers moved West, the gold seekers got most of the attention and publicity. But more of settlers traveled West for a less exciting reason—to farm.

In many cases, it never occurred to them that the land might not be suitable for the purpose. Some reports reached the East about desert lands, but they circulated mostly in educated circles. More common was talk of the fertility of Oregon, California and other places. Besides, farming increased rainfall.

As white settlement moved West, the federal government sent four survey parties to case the joint. Led by Clarence King (1867-78), George Wheeler (1872-79), Ferdinand Hayden (1867-78) and John Wesley Powell (1869-1879), they took scientific approaches to their work.

The experience of Powell in trying to give the public reliable information on the West and water, and Congress’ effort to discredit science, provided an early model that politicians follow to this day.

John Wesley Powell was not the usual dashing explorer type. Relatively short, he lost a forearm in the Civil War. After the war, he was a natural sciences professor and later became curator of the Illinois Natural History Society Museum. But to a populace that did not usuallysee their heroes, he was dashing enough.

He and the nine men he led launched in four boats onto the Green River in Wyoming on May 24, 1869, joining the Colorado River downstream. In Utah, they lost provisions, some instruments and one of the boats. On Aug. 5, they entered the Grand Canyon. Rapids nearly ended the expedition, and the party became divided and demoralized. It split up, with three departing to die on the trail. The rest continued with Powell, and they reached what is now the site of Lake Mead, where he called the journey a halt.

Two years later, Powell led an 11-person crew on another exploration, this one lasting 17 months. He began writing about the expeditions and became first director of the Smithsonian’s Bureau of Ethnology, and was then U.S. Geological Survey director from 1881 to 1894. He was in a position to influence public policy on much of what he and the other scientists in his parties had learned in the West.

Report of the Exploration of the Columbia River of the West and Its Tributarieswas published in 1875. It was not what the members of Congress, who had funded the surveys, were expecting. Nor was Powell’s subsequent report,Lands of the Arid Region of the United States(1878), which contained an objectionable adjective right in its title.

Senators from Western states already admitted to the union—California, Nevada, Colorado, Oregon—were disbelieving. How could they attract new settlers and businesses to their states if they were described as arid—much less as deserts? Territories—the Dakotas, Montana, Washington, Idaho, Wyoming, Utah—had similar concerns.

The arid region, according to Powell’s reports, begins about midway in the Great Plains and extends across the Rocky Mountains to the Pacific Ocean. Powell pulled in most of the area where rainfall was less than 20 inches. He wasn’t wrong—but his reality did not fit the image of the West that had been created in the East.

Powell wanted planning that avoided the disruption of communities and made the best use of water for the largest number of settlers—not for the large ranches and farm operators.

New arrivals who were allowed to choose from any public lands would likely settle along rivers—that is, in flood plains—or on land with low productivity at high elevations that would gobble three or four times more water than more fertile land in the valleys. The rampant fraud that accompanied the Homestead Act—doghouses built on homesteads by phantom settlers to satisfy the residence requirement in order to obtain the water allotment for larger operations—was another of Powell’s targets. He proposed that settlers choose their lands from those designated irrigable, not from any public lands. In one stroke, large monopolies would have been dealt a blow, and the success rates of families would have risen dramatically.

But small farming families do not fund U.S. House campaigns or provide the money for bribery in an era when U.S. senators were appointed by state legislators.

Nevada’s U.S. Sen. William Stewart had initially supported Powell, co-sponsoring a study of whether Powell’s agency should inventory what public lands were and were not irrigable. The two men traveled in the Middle Border territories together—and the trip did not irrigate the relationship. They addressed the North Dakota constitutional convention and other groups, and became better acquainted with one another’s views.

Thereafter, Stewart emerged as a fierce critic. Stewart, a mining lawyer with dubious ethics who believed the West was there to be plundered—preferably by his big-business cronies—supported irrigation, but not necessarily rules and niceties.

Powell, with 20 years of experience in the West to draw on, filed reports filled with terms likearid anddesert, terms that grated on the sensibilities of congressmembers:

“In very low altitudes and latitudes the grasses are so scant as to be of no value; here the true deserts are found. These conditions obtain in southern California, southern Nevada, southern Arizona and southern New Mexico, where broad reaches of land are naked of vegetation, but in ascending to the higher lands the grass steadily improves. … In addition to the desert lands mentioned, other large deductions must be made from the area of the pasturage lands. … If the filling of the streams and the rise of the lake were due to a transient extreme of climate, that extreme would be followed by a return to a mean condition, or perhaps by an oscillation in the opposite direction, and a large share of the fields now productive would be stricken by drought and returned to the desert. … Near to the mountains the grass lands are fair but they have been overpastured and greatly injured. Out among the Basin Ranges little grass land of value is found. … Their streams are spent before the summer comes; and only a few springs are perennial. The result is a general desert, dotted by a few oases.”

Powell recommended that Congress withdraw all public lands “of the arid region from ’sale, entry, settlement, or occupation,’ except those selected as irrigable lands, and to allow titles to irrigable lands to be acquired only through the operation of the homestead laws and the desert-land laws.”


U.S. Sen. Gideon Moody/1890: “Of course, I have got a great respect for scientifically educated gentlemen, and I am always very much interested in their researches and all that, but …”

When congressional hearings were held on the Powell reports, they were rough for him. Wallace Stegner later wrote, “They wanted to know who had defined the ’arid region,’ and implied that it was a fiction of Powell’s own, designed to get him extra powers.”

U.S. Sen. Gideon Moody of South Dakota, a lawyer from Deadwood, asked about wells as a source of irrigation. Wheeler candidly said all the artesian wells in South Dakota could irrigate only a single county. Away went Moody’s support for science—and for Powell.

Some of the 19th century legislators decided there must be alternatives to Powell who would tell them what they wanted to hear—just as 20th-century tobacco industry and 21st-century Republicans, when confronted with unfavorable science, went shopping for different scientists. There were takers—not many, because Powell’s science was sound. But cherry-picking is the name of this game, and enough rent-a-scientists and rivals of Powell could be found.

Thus came rain-follows-the-plow. According to a pseudo-science of the time, if land was plowed and cultivated, rainfall would increase. We are not making this up. The term was coined by Charles Dana Wilber, who wrote:

“Suppose (a section of farmers) 50 miles, in width, from Manitoba to Texas, could acting in concert, turn over the prairie sod, and after deep plowing and receiving the rain and moisture, present a new surface of green growing crops instead of dry, hard baked earth covered with sparse buffalo grass. No one can question or doubt the inevitable effect of this cooling condensing surface upon the moisture in the atmosphere as it moves over by the Western winds. A reduction of temperature must at once occur, accompanied by the usual phenomena of showers. … To be more concise, Rain follows the plow.”

In addition, Powell had his rivals, and congressmembers gave them forums to smear Powell and/or just to spread a less reliable version of science. Paleontologist/ichthyologist Edward Cope planted nasty stories about Powell in a New York newspaper.

After Powell’s death years later, his geographer colleague, William M. Davis, would write, “Powell’s large share in promoting a correct knowledge of the arid parts of the United States and their possible utilization will not be realized by readers today unless they recall the time when so much was said about taking the words ’Great American Desert’ off the map.”

But Stewart and company did not represent all congressional sentiment and in 1888, Congress closed public lands to settlement until Powell’s agency could classify the lands of the West as irrigable or otherwise.

But the West was a big place, and lawmakers like Stewart wanted the classification of lands done yesterday. Powell estimated it would take six to seven years to complete. There were speculators, rainmakers and others of more serious intent who were not willing to wait. As the years passed, pressure built on members of Congress to throw open the public domain. When they were pressured, they needed someone to blame. Powell was handy.

Just as current lawmakers attack Barack Obama for using the power Congress gave him to create national monuments, legislators were soon blaming Powell for the moratorium on settling public lands they had enacted. They found other grounds on which to make a case against him, too. He believed in small farms, because it appeared that no more than 20 percent of the public lands were irrigable, and he considered it criminal to let people settle on plots “where they cannot maintain themselves.” Nor was Powell as susceptible to influence as congressmembers. “It is to be borne in mind that this survey is not primarily designed for the benefit of private person,” he wrote. Of couse, he considered rain-follows-the-plow nonsense.

But members of Congress were losing their patience, and they finally repealed the closure of public lands before Powell’s work was complete. The public domain was thrown open to however anyone wanted to use it.

As “private persons” tried to make irrigation work in the West, the West became littered with failed irrigation projects. One was headed by Francis Newlands, a Californian whose political career had stagnated here. He turned to Nevada for better luck after marrying money. He lost about a half million of it on his Truckee Irrigation Project, deciding thereafter that the public’s money was needed for desert reclamation—“reclaiming” the desert for agriculture. In 1902, as a U.S. House member from Nevada, he won passage of the Reclamation Act. The Act provided for the kind of farms that might succeed in the wet and fertile East—160 acres (320 for a married couple).


Leah J. Wilds, Danny A. Gonzales and Glen S. Krutz/1994: “And finally, U.S. Bureau of Reclamation water is among the most inexpensive (at least for irrigated agriculture), highly subsidized, and inefficiently used water in the American West.”

Some projects, such as construction of the Hoover Dam, require government aid, because so much capital is needed that private companies cannot accomplish it. But it should have occurred to someone that the reason commercial irrigation projects failed was not that they were underfinanced, but that most of them simply didn’t work or make profits—meaning that a government program would face the same problem. It might also have prompted officials to start with model projects and see what worked and what didn’t. Instead, within days of the enactment of the Act, five projects were announced in five states—followed by dozens more. Within a decade, the program was bankrupt.

The money troubles didn’t slow reclamation down. Congress pumped a loan from the treasury into the act, keeping it alive. In 20 years, the loan was unpaid, and most projects were losing money.

As the reclamation projects failed, they drifted along on federal loans, interest exemptions, subsidies and extended payment periods. Eventually, the federal government started building often unnecessary hydroelectric dams to generate revenue to pay for the money-losing reclamation projects. As the projects piled up, the pool of red ink became wider and deeper, which is more than could be said of the water that fed them. Western farmers were being subsidized to grow crops that Eastern farmers were being paid not to grow. In fact, if the West had more rivers, the Bureau of Reclamation and the Army Corps of Engineers might have bankrupted the United States of America.

As competition for dam-building grew between the two federal dam building agencies, dam building took on a life of its own. (It’s not clear why two agencies were allowed to perform the work.) Hundreds of dams went up, and slowly, likely sites for dams dwindled. Possible uses for dams—water supply, irrigation, flood control, hydroelectricity—became satisfied.

Yet the dam-building went on—not for any particular reason, except dam-building itself. It became a bureaucratic perpetual-motion machine. Internal federal paperwork later disclosed showed the worthlessness and lack of necessity of dams built.

Worse, dams became part of doing business in Congress—“a kind of currency,” water historian Marc Reisner wrote in 1986. Congress had literally become unable to function without water projects to trade.

Many of these dam projects, because of the massive surfaces of the reservoirs, wasted through evaporation the water they were supposed to conserve.

“Excessive reservoir storage increases consumptive losses in the form of evaporation and seepage,” author John Weisheit wrote. “Over-developing the watershed with numerous diversions and reservoirs also decreases the quality of the water by loading the river water with salt and heavy metals.”

We hear about the evaporation that results from lawn-watering, but not the evaporation that results from huge storage reservoirs built to keep a failing program alive. In 1962, the Interior Department analyzed and approved four huge water projects—Glen Canyon, Flaming Gorge, Curecanti and Navajo—by intentionally excluding from its calculations the terrific wastage of water in evaporation from the surface of their reservoirs.

To keep getting more welfare for their constituents, the successors of the lawmakers who denied that the West was arid asked for the sympathy of their colleagues—on the grounds that the Western farmers were developing land that was arid.


Former U.S. commissioner of reclamation Dan Beard/2015: “I mean it costs us $100 to deliver an acre foot of water, and we charge the farmers $2.”

In 1977, President Jimmy Carter tried to get the program under control by cutting off money for 19 water projects. Congress erupted in an uproar, with Carter’s fellow Democrats leading the charge, though Republicans were still heard from. Enough Democrats stood by Carter to make a veto fight of it—and then Carter caved in.

However weak his leadership was, it was Carter who was on the side of history. Once he pulled the curtain back, dam-building never had its same sacrosanct standing again, and the environmental movement’s growing influence, together with wildly rising construction costs, eventually put an end to the era of dam building. There would still be occasional dams built, but the frenzied annual monsoon of water projects that Congress once disgorged was facing a sharp decline—and some already existing dams would start coming down.

But the anti-scientific techniques that have kept water wastage in the West alive for more than a century have now been turned to use in promoting the continuing deterioration of climate.

A 2013 study from University of Nevada, Reno hydrologist Thomas Myers, published in the Journal of the American Water Resources Association indicates that just one artificial federal lake loses up to 380,000 acre-feet of water each year.

Its name? Lake Powell.

One reply on “Water Wars: Politics Has Always Trumped Science in the West”

  1. Thanks, Dennis!!

    Very informative article, shows how development AND big farming interests have set a phony water use agenda. With so many straws in the glass and so many oxen being gored, it will be very hard to change perceptions to enable water to be used rationally. But spreading this story widely is a good start.
