Introduction & Overview

Coolidge Dam creation involved a wide-ranging cast of characters.*

Few Arizonans have heard of Coolidge Dam. Fewer Arizonans have been there and far fewer know the story.

The Story of Coolidge Dan is all about People.

Historic Coolidge Dam was built in the late 1920's where the fabled Gila River runs through San Carlos Apache Tribal land straddling the Pinal-Gila County Line at the head of Box Canyon..

The epic water rights plight of the Pima & Maricopa Indians foreshadowed Coolidge Dam's creation.

An uncommon alliance of Indians, politicians, missionaries, farmers, civic boosters and ordinary Arizonans finally pushed legislation through Congress enabling construction of a Gila River dam.

Celebration and rejoicing broke out when President Calvin Coolidge signed the legislation into law June 7, 1924.

A unique multi-dome design quickly set Coolidge Dam apart and helped contractors finish dam construction one year ahead of schedule in late 1928.

The dam's namesake Calvin Coolidge spoke at a gala dedication March 4, 1930, attended by about 10,000 people.

Coolidge dedicated the dam "to the advancement of the nation, to the benefits of education, to the making of better homes, and the making of a better country."

The reservoir behind Coolidge Dam eventually spawned a once regionally renowned sport fishery but it was a bittersweet benefit for San Carlos Apache Tribal members who received practically no compensation for loss of ancestral lands, grave sites, displacement of over 500 Natives and the total destruction of Old San Carlos.

Coolidge Dam has survived the slings and shocks of several major floods. Numerous retrofits and engineering tweaks have helped the iconic arched domes weather tough times and stand tall at the head of rugged San Carlos Box Canyon.

As Coolidge Dam approaches a Centennial, its legacy remains a remarkable chapter in the cavalcade of Arizona history.

What this blog is...and what it isn't...

Hello, I am John Parsons, a history enthusiast and 70-something retiree who lives in Rimrock, Arizona. Early in 2022 I became very interested in the history of Coolidge Dam. The more I studied that history the more I realized both its complexity and its obscurity.  I have found not a single source that tells the full Big Picture Story of Coolidge Dam.  There are lots of sources that have plenty of bits and pieces of Coolidge Dam history but none cover all the bases.

That's when I decided to create this blog as a means to discuss each segment of the story. No man made object exists in a vacuum and certainly not Coolidge Dam.  It was created as a product of its times and involved so much more than simply designing and building a dam on a desert river.

This blog is not a scholarly article.  Nor is it an opinion piece.  I have no agenda in studying Coolidge Dam.  While I have tried to cite sources for much of my material, I fall far short in providing complete and comprehensive primary reference sources.

I have subdivided the Coolidge Dam Story into ten segments, not including this introduction.  Each segment starts out with a 200-300 word personal narrative.  For this project I read seemingly countless scholarly dissertations, government reports, journal articles, media accounts and so much more.  In each segment's introductory narrative, I have tried to summarize my understanding of what I have read into an interpretation I hope everyone can understand.

I make no claim that my interpretation of what I have read is THE only and final word on the subject.  My narratives are simply my own view and synthesis of what I have studied.  I hope that perhaps some of my readers will be motivated to begin their own study of The Coolidge Dam Story.  The more the merrier!

I would like to emphasize this is a totally non-commercial blog.  It has no ads and will never have any ads.  Likewise, I am not connected, affiliated, recognized, assisted or otherwise associated with any private, county, state, federal, college or university entities of any kind.  This blog has been created and is maintained solely by John Parsons, Rimrock, Arizona.

As always, this and any other of my many blogs will forever be considered a "work-in-progress".  If you have comments, suggestions, edits, corrections or other need to contact John Parsons, please use: arizonahistorystories@gmail.com

The following is a list of topics discussed here.  Additional topics may be added to this list as the blog develops.  
*The photo collage at the top of this post shows those I believe to be the so-called "major players" in The Coolidge Dam Story ranked in order of importance top to bottom.  In the top row (l-r) we have Rev. Dirk Lay, a Gila River Indian Community ancestor and Judge Baughn.

In the second row (l-r) you see Representative Carl Hayden at Sacaton in 1913; a San Carlos Apache man at Omaha's 1898 Indian Congress and the shadowy face of Charles Real Olberg, Coolidge Dam designer and engineer.

In the third row at bottom (l-r) we placed Senator Henry Ashurst, President Calvin Coolidge and, finally Senator Ralph Cameron. 
Millions of years before the Gila River had a name or fluvial face, powerful, earth-shattering geologic forces were ripping apart and thrusting mountain ranges into the sky.  Cavernous, yawning basins between those ranges became giant catcher's mitts for rocks, gravel, sand and soil being washed down from the mighty mountains.  A few thousand years go when the first humans finally set foot into the verdant valleys between those old mountain ranges, the water, land, plants and animals had reached a steady state of equilibrium.  Although those early people had their own names for the water flowing across the land, it was the Spanish who gave The Gila River its name.
  The Pima People who first happily greeted Spanish, Mexicans and Americas traveling through their homelands are descendants of pre-historic people who began began farming along The Gila River at least two thousand years ago.  Over the centuries that farming flourished along The Gila River, Natives learned to be ever more successful at coaxing crops from the sun-baked desert soils.  In fact, farms of The Pima People were widely considered a veritable cornucopia of life-sustaining foodstuffs.  The Pima People probably reached their zenith of agricultural success in 1860 when they produced over 11-million pounds of wheat!  When homesteaders by the score and then the 100's began hodgepodge farming and haphazard diversion of The Gila River upstream, the handwriting was on the wall for the Pima culture.  Meanwhile cattle ranchers flocked to the illusion of easy money in Arizona, bringing nearly two million ungulates many of which overgrazed the pristine rangelands of The Upper Gila River. The combination of upriver diversions and destruction of native grasslands sparked a precipitous decline in Pima culture which nearly disintegrated because of the resulting lack of life-giving water from The Gila River.
The inevitable march of progress had largely tamed, civilized and developed the sprawling region of which Coolidge Dam would become a part.  San Carlos Apache Reservation lands occupied the dam site and all of its proposed reservoir.  A bustling railroad ran alongside The Gila and San Carlos Rivers.  Wagon roads had morphed into automobile routes which connected the mining, tribal and agricultural settlements scattered through the valleys and mountains. San Carlos Apache Tribal members had long since settled into a sedentary lifestyle on an old U.S. Army post located at the confluence of the Gila and San Carlos Rivers. Once pioneer outposts in Arizona's Gila Valley were now prospering agricultural communities that also profited from trade with nearby mining camps.  Downriver, most of the arable land in the Middle Gila was occupied by either Native or white farmers who tried to eek out a living with unpredictable water supplies.  Discussion of a Gila River dam began in the late 1880's and the Coolidge Dam site was actually first identified and described in the 1890's.  The water rights plight of The Pima People was well known among local political and ecclesiastical leaders.
The long and winding road that eventually led to creation of Coolidge Dam was far more than a so-called legislative process.  It had its roots in sensitive awareness of the water rights plight of The Pima People.  Famed Carl Hayden actually had a Pima nanny as a child. The legendary Pima missionary Charles H. Cook began quietly working to raise awareness in the 1890's. As soon as Hayden took office as Arizona's first Representative following 1912 Statehood, he began working legislation that laid the foundation for Coolidge Dam.  Rev. Dirk Lay arrived on The Pima Reservation in September 1910 and he quickly picked up the baton from Rev. Cook.  Prominent local Middle Gila community leaders worked together to scheme and plot ways to get a dam on The Gila River.  Rev. Lay toured the Nation to build support for The Pima People.  Judge Baughn wisely assessed the 1920 Senatorial election and provided candidate Ralph Cameron with a tailor-made campaign issue---getting a dam on The Gila.  It fit right into Cameron's devious endeavors to take over the Colorado River.  Finally, Hayden and equally legendary Senator Henry Ashurst saw their "window" and called together The Players in December 1923.  They convinced Ralph Cameron to introduce the bill in his name and then they completely unleashed Dirk Lay.  He and his wife moved to Washington D.C. and operated out of a room in Cameron's office complex.  They coordinated a mass national lobbying effort from church assemblies of many faiths. Their face-to-face lobbying remains the stuff of legend.  After Cameron's bill passed both chambers by unanimous vote, Silent Cal Coolidge balked at signing it.  Hayden and Ashurst took him out in the hallway and offered to name the dam for him if he signed it.
Coolidge used a pen inscribed to Rev. Dirk Lay to ink the bill into law.
Ralph Cameron continues to get credit for the so-called 'Cameron Bill" which was signed into law to create Coolidge Dam.  Cameron had used a Gila River Dam as a campaign issue, promising to get it done in his first year.  Of course, he forgot all about his campaign promise as soon as he was sworn in.
Cameron was 100% out for himself.  He used what we now call Dark Money to get himself elected. The primary reason he ran for Senate in the first place was to use the influence of his office to further his personal schemes on the Colorado River.  Cameron has filed many, many bogus mining claims to tie up public access at Grand Canyon and also practically all of the prime dam sites on the river.  He skirted the razor's edge of the law for many years, using a bogus salted platinum mining claim as a lynchpin of his river schemes.  He filed numerous placer mining claims on the bed of the Colorado River to try to personally profit from hydro development.  The 20-20 spotlight of history's hindsight has not been kind to Ralph Cameron.  He has come out looking and acting like a cheap charlatan willing to dupe the public any chance he had.  We suspect he was "all in" on the Gila River dam because he thought it might bode well for his Colorado River schemes and dreams. Hayden defeated Cameron in 1926 and went on to be Arizona's longest serving Senator.
People throughout Arizona and especially in the Middle Gila were following the epic lawmaking process almost like it was a sporting event.  Newspapers carried regular reports and editorials.  Local leaders held meetings to discuss progress... or lack thereof.  Many large church congregations nationwide kept abreast of the process. When President Coolidge signed the bill into law on June 7, 1924, all of the pent up energy burst loose in a wave of joyous celebrations, especially in the Middle Gila.  Newspaper accounts of the celebrations still convey the sheer excitement of those times.
After the euphoria of Coolidge's signature faded away, the hard work and heavy lifting began. The Indian Service has never designed anything remotely resembling what would become Coolidge Dam.  Big Dams were the work of the US Bureau of Reclamation.  Privately, engineers and politicians scoffed at the idea the Indian Service could design such a big dam.  Luckily, the Indian Service had a secret weapon--Charles Real Olberg, a brilliant, out-of-the-box thinker and designer.  Olberg shocked even his colleagues when he unveiled the multiple dome-buttress design for the dam.  The higher-ups at the Indian Service were so skeptical they had to run the design past all sorts of reviewers.  But Olberg's design passed with flying colors and so design specs were finalized and a call for bids put out.  There's quite a story about the winner bidder's bid submission!  Anyway, the contractor really knew the ropes and put together an All Star Team which quite literally knocked out the dam in amazing time, finishing a year ahead of schedule.
Even after the dam was finished and turned over to the government, there were quite a few smaller details to be worked out before the dam could be called truly complete.  By late 1929, Indian Service functionaries were already hard at work planning a gala Dedication.  The March 4, 1930, event came off without a hitch.  Former President Calvin Coolidge attended and spoke. However, he made it clear he really didn't want to be there.  His was a truly remarkably dull address!  Will Rogers was Master of Ceremonies and provided everyone's most memorable quotes of the day.  About 10,000 people attended and dozens of them were fed a VIP lunch on tables set up in the roadway across the top of the dam.  
We have included a separate segment on the live radio broadcast of the Dedication Ceremony, even though technically a live radio remote is not part of Coolidge Dam itself.  Coolidge Dam's Dedication provided the impetus for media movers and shakers of the era to set up and facilitate the radio remote.  It was a major milestone in early Arizona media operations.
In this section we will discuss such things are reservoir levels, the epic 1993 fill and spill, and various "improvement" projects that have taken place over the decades.



The Gila River

Any discussion of Coolidge Dam simply can't be complete without a decent overview of The Gila River.  The total watershed area of The Gila River is 58,200* square miles but "only" 12,886** square miles are located above Coolidge Dam.  The confluence of the East and West Forks are widely considered to be the point of beginning of The Gila River itself.  The river stretches 259 miles between that confluence and Coolidge Dam.

The true birth places of The Gila River could also be considered the heads of The East, Middle and West Forks of The Gila.  The length of those streams could add another 40-50 miles to the 259 mile primary reach of The Gila about Coolidge.

River runner, hydrologist, engineer and author Jon Fuller provided the river mileage information above.  Fuller's book "Gila River Elegy: Paddling America's Most Endangered River" is The Best and Only accurate source of information about the current nature and characteristics of the entire Gila River from its source to the Colorado River at Yuma.  However, various private, non-profit and government websites provide a plethora of information about The Gila River.

Above is a simplified depiction of the Gila River watershed above Coolidge Dam.

The far Upper Gila River Watershed is colored orange above.  The San Francisco River Watershed contributes nearly as much area and runoff as does the Gila River watershed.  Together the Gila and San Francisco Rivers form the mainstem Gila River heading into the Arizona heartlands.
Prior to the 1880's, The Gila River and its tributaries produced relatively stable runoff regimes.
Massive over grazing in the 1880's forever changed all aspects of The Gila River's vast watershed.  The Upper Gila was particularly hard hit by the grazing free-for-all that reigned in the 1880's. Once the land was stripped of stabilizing native vegetation, snowmelt and summer storm runoff reached dizzying proportions and locomotive speed.  The Gila River channel in places went from barely 200 feet wide to as much as two miles across.  A stream that once provided clear, life-giving perennial river flow became widely known as the "World Muddiest River." (Ross Calvin* 1946 Pages 135-153)

The 1891 Flood is by consensus the biggest, baddest ever to molest The Gila River.  No precise peak flow has ever been pinned down for 1891 but ballpark estimates range anywhere from 150,000 cfs in the upper watershed to 300,000 cfs in the low Gila River below Phoenix.  Gargantuan floods also took place in 1905-06 and 1916.

Even today, water managers in charge of releases from Coolidge Dam consider the Gila River a fickle watershed.  They generally tend to count on reservoir rises when it rains on snow in the New Mexico mountains.  Those water managers have become so gun-shy over decades of dealing with the feast or famine Gila River runoff that they take the reservoir level on January 1 each year as their management baseline.

A substantial wilderness-style river run exists between Coolidge Dam and Winkleman.  It is called by various names: San Carlos Canyon, Box Canyon, Needle's Eye, and others. Coolidge Dam was sited at the head of this canyon, the last major such canyon along the 650+ miles of The Gila River.  The Hayes Mountain form the northern portion of this area and the Mescal Mountains the southern sector. For those few intrepid river runners who have paddled that stretch, it is considered to be one of the finest inland desert runs in The Southwest.

The Gila River often leaves Coolidge with nothing to do.  The reservoir has been dry approximately 20 times and fully overflowing only once in 1993.  The reservoir has been full several times but generally is far from full.  As of March 5, 2022, so-called San Carlos Lake contained 30,353 acre-feet of water was was roughly 3-4 percent full.
People have been writing about the Gila River for almost 400 years.  The amount written about the Gila has only increased over time.  If legal documents and lawsuit filings  are included in the "writings" of The Gila River, there would be enough pages to fill a medium-sized city library.  to full discuss The Gila River and its watershed is far beyond the scope of our simple blog.  However, we will continue to add interesting links to this page.  Here are a couple to get you started:

Here are a couple of fun facts about The Gila River watershed:

* The full Gila River watershed is bigger in area than 30 of the US states.
** The Gila River watershed above Coolidge Dam is larger in area than the combined states of Massachusetts and Connecticut. (12,886 vs 12,683)

Once upon a time, The Gila River was lined with mature, old-growth cottonwood and willow trees.  With overgrazing and over-diversion of the river's scant water resources, invasion tamarisk trees took over many miles of river channel. In many places, the tamarisk grow too thick for humans to penetrate.  Occasionally, those invasive trees will catch fire, either by natural or human causes.  They burn hot and put on a spectacular show.  We wrote an interesting comparison between the "flaming rivers" of the Gila and Ohio's Cuyahoga.  To read it visit:

The Pima Indians


 



the Pima and Maricopa harvested 11,640,000 pounds of wheat and 15,120,000 pounds of corn in 1860. In addition, they harvested 480,000 pounds of beans, 9,200 pounds of cotton, 4,978 pounds of tobacco, and 1,950 gallons of saguaro preserves, and raised more than 700 oxen and cattle.

our lifeblood -Gila River water - was cut off in the 1870s and 1880s by construction of upstream diversion structures and dams by non-Native farmers, and our farming was largely wiped out. From 1880 to 1920 or so, we faced mass famine and starvation.

The Gila River Indian Community (GRIC) is nearly 600 square miles and is primarily a rural community with wildland/urban interface areas and numerous archeological sites of cultural and spiritual significance. There are over 70 miles of state and interstate highways, large farming operations, major infrastructure, improved and rural housing developments, 12 schools, 3 industrial developments, 3 large scale casinos, an upscale outlet mall, world class golf, a major raceway, a professional soccer stadium, large entertainment venues, 2 large hotels and a 4 star hotel resort.  Significant public safety infrastructure is required to mitigate the risks associated with GRIC’s enterprizes, government, topography and proximity to Phoenix and the US Border.

The pre-dam perspectives

Construction of Coolidge Dam wrecked havoc with the status quo of San Carlos Apache Tribe Reservation lands. By the early 1920's, hundreds of San Carlos Apache Tribal members lived a relatively secure lifestyle on alluvial flats near the confluence of the San Carlos and Gila Rivers.  About 1,000 acres was cultivated for food and forage.  Small cattle herds were grazed along the rivers and adjacent areas.  Reservation administration and trading activities took place in the remnants of an 1870's US Army post. A busy railroad ran alongside both rivers.  Tribal members still enjoyed free passage on the railroad from a February 1898 agreement to allow the iron horse on their lands.

Rather suddenly and without much prior notice, San Carlos Apache Tribal (SCAT) members were facing eviction from their beloved home land down by the riversides. Their federal Indian Service overseers; resident missionaries and even visiting Pima Indians were giving the Apaches all sorts of sales pitches to give up their land for a reservoir of no benefit to them.

When SCAT members spoke up for their ancestors buried in a cemetery targeted for inundation, Lutheran Rev. Alfred Uplegger "pointed out to the believers that just as World War soldiers buried at sea would arise from the dead, their loved ones buried under the proposed San Carlos Lake would also arise."*

Although some cash was provided to help move nearly 500 SCAT members, the loss of valuable farm land and their "home town" yielded practically nothing. Ironically, when the SCAT had negotiated a right-of-way for the railroad, SCAT received numerous benefits and essentially lost very little actual land in the agreement.

The difference appears that the Indian Agent Lt. Sedgwick Rice went to bat for SCAT in 1898 while SCAT appeared to have had no real advocate during the so-called negotiations to give up their land for a reservoir behind a dam on their land.**

See: http://www.sancarlosapache.com/San_Carlos_Culture_Center.htm

What was once an area rich in ancestral Apache activities and scattered Family settlements was wiped out by the reservoir behind Coolidge Dam, ironically labeled "San Carlos Lake."  The inundated settled became known as Old San Carlos.  Hundreds of Natives were relocated many miles north to New San Carlos.  The photo source is from an excellent website that provides an excellent overview of the few faint remnants left of Old San Carlos. See: http://www.azbackcountryadventures.com/osc.htm

Above is a good map depiction of the Old San Carlos area before it was inundated.

"Alfred (circled in red) was resident m1ss10nary at old San Carlos when the government wanted to dam the Gila River to provide needed water for Pima Indian farmers, and Apaches objected. In their largest community at old San Carlos, which would have to be flooded, they lived in houses as well as wickiups, had a cemetery and many of them cultivated fruit trees, gardens and farms. These Apaches had a water problem, too. They were plagued by hot, dry seasons and flash floods that washed out their irrigation ditches. The Apaches did not want to give up their homes and farms or to have their cemetery covered with water. A mass meeting was held.  Representatives of the Gila River Reservation came and appealed on behalf of the Pima Indians. A government representative urged the Apaches to give their permission which would allow the dam to be built. He told them they would be moved to other settlements with new and better irrigated farms and also, for several years during the construction of the dam, many Apaches would have cash jobs.

Reverend Alfred pointed out to the believers that just as World War soldiers buried at sea would arise from the dead, their loved ones buried under the proposed San Carlos Lake would also arise. Then he asked the un-believers what difference it would make to them, any-way. He asked all to have brotherly love for their neighbors, the Pimas, and give their consent. Eventually Apache leaders agreed to permit the dam to be built and those who could not write put their fingerprints on the document."

The Legislative Process

 







Pushing Congress to create what was called "The San Carlos Project" took decades and a lot of work by a lot of people.  We'll add here what we can find about it.



Sensing that the most important obstacles to the San Carlos bill had been removed, in the fall of 1923 Hayden called together Ashurst, Cameron, and San Carlos Association representatives for a series of strategy meetings, most of which took place in Hayden's office. As a result, on December 11, Cameron-Arizona's lone Republican in Washington-introduced in the Republican-controlled Senate a bill (S. 966) "to continue construction of the San Carlos Federal Irrigation Project." While Ashurst lobbied for the support of "every Democrat in the Senate," Republicans-pleased to have one of their number in the upper house from traditionally Democratic Arizona fell in line behind Cameron. On April 23, 1924, the Senate, in a rare display of unanimity on a floor vote, passed the San Carlos Project bill.

Rosy predictions notwithstanding, President Coolidge had yet to sign the bill. The conference committee had completed its report and Congress had approved $5,500,000 for construction of the dam and accoutrements, but Coolidge complained that the project would place too heavy a burden on taxpayers. Hayden quickly arranged a meeting with Interior Secretary Work and Commissioner of Indian Affairs Burke, seeking their advice on how best to avoid a presidential veto. They suggested naming the structure "Coolidge Dam.” Hayden liked the idea. Along with Ashurst, he met Coolidge at the White House and informed the president that the "marvelous structure” on the Gila River would bear his name. Evidently, the flattery worked, and on June 7, 1924, Coolidge signed the San Carlos Project.

After finishing Presbyterian seminary, young and outspoken Rev. Dirk Lay became a missionary in Sacaton, where he would dedicate over 25 years to helping the Akimel O’odham, or “River People.” He replaced the Rev. Charles H. Cook, who had established the first Indian school in Arizona in Sacaton in 1871. For several years, Lay raised money to build a church in Sacaton, on the Gila River Indian Community. Built in 1918, Cook Memorial Church is a two-story, mission-style adobe church with a large sanctuary and a basement and is still standing today.

Perhaps Lay’s greatest accomplishment, however, was lobbying for water rights for the Gila River people. “I looked about at the Pima people,” Lay said. “I felt that fighting in their cause was worth a lifetime of effort.” Because of his efforts, in part, Coolidge Dam was built in 1928 along the Gila River, and the San Carlos Irrigation Project was created. Later, as a member of the U.S. Army Chaplain Corps, Lay’s regiment was ordered to Panama, where he died of a heart attack in 1944. Dirk Lay Road in Sacaton is named in his honor.

Design & Construction

 



Coolidge Dam was the first water storage facility ever constructed using a multiple dome design . Described simply, the design consists of two buttresses supporting three inclined eggshaped domes. The small end of the dome rests on the foundation, while the wider end, where the curve has a longer radius, is above. The domes are heavily reinforced with steel bars placed in the planes of the inclined arches from abutment to abutment. The buttresses are nearly triangular in shape. They are sixtyfeet thick at the base, twenty-four feet thick one hundred feet below the crest and sixty- two feet thick at the top. They are flared toward the upstream side of the dam to properly support the domes. The buttresses are reinforced with horizontal steel bars. There are two inclined contraction joints in the lower part of each buttress to prevent irregular cracks due to concrete shrinkage.


We think that design and construction of Coolidge Dam deserves a book length treatment.  Consequently, we will only cover the basics here and provides links for further reading.

The gala dedication of Coolidge Dam attracted its namesake, former President Calvin Coolidge and about 10,000 other people, too.  Details of this are truly fascinating and will be covered here.

Live radio remote

The 1930 Dedication was a huge Big Deal in Arizona. As a result, "The Arizona Republican" newspaper leadership decided to use their flagship radio station KTAR to broadcast the event live throughout the State of Arizona.  It was a technological feat that deserves attention in its own right.  

A newsreel film of the Dedication was converted to video here:

Above, "Silent Cal" speaks into the KTAR microphone on a bunting-draped podium atop Coolidge Dam. Coolidge's speech was a boring dud and he as much as told people he really didn't want to be there.  The radio remote, however, covered the entire event so Coolidge's unimpressive speech was a mere footnote during the almost four hours of air time.

Luckily, "The Arizona Republican" chose to brag about the radio remote and the above article provided all of the intimate details people like me would like to know 92 years later.

Radio heads I've talked with feel certain the audio feed was carried by copper wire telephone lines from the dam site to Phoenix.  Consequently, the broadcast had to go through at least the main Phoenix switchboard.  We'd guess the remote was such a Big Deal that telephone and radio managers worked together to get a clean, dedicated patch for the audio feed from the dam site. Even though this photo of a metro switchboard dates earlier than 1930, it conveys what such a situation might have looked like.

The above photo shows what a typical 1000 watt transmitter looked like in the 20's.  It's laughably crude compared with today's high tech arrays but it got the job done...and done well.


Above are the twin broadcast antenna towers that beamed the Dedication event statewide.  Back then 1000 watts was considered high power.  However, it's a wonder that such low power could push the signal all over the state.  Talk about a 1920's techno feat! WOW!

Radio took over America in the 1920's.  There were even radio stores where people went specifically to shop for a home radio set.  The photo above shows what such a store would have looked like.  We can imagine the smooth upselling techniques of the salesman.  "But, Sir, this one with TEN tubes would have so much more clarity than the five tube radio!"


This is a reasonable fascimile of what it might have looked like when people tuned in to listen to the Coolidge Dam radio broadcast.  Sitting around the gi-normous home radio in the living room was THE thing to do back then.
