Santa Cruz Dam History - Part 3


As built by Texas contractors, Chris J Veesaert says the Santa Cruz dam was “unstable seismically.” In a ten-year type flood, the spillway would have been overtopped and the dam would likely have failed in a more serious flood. The Bureau of Reclamation redesigned it to be overtopped safely and built a “stabilizing arched buttress against the downstream face” to prevent failure from “erosion of the intensely-fractured granitic supporting abutment rock.”

They couldn’t do anything about the silt that has accumulated at the bottom, reducing the capacity by 34%. When the district releases 8' of water for irrigation, the lake’s fishing dock is no longer usable. The irrigation district has been trying to increase the height of the dam to the level approved in 1929.

In 2000 Congress allocated $100,000 to study the sediment problem. John McCain protested it was an intolerable earmark.

In 2010 the Corps of Engineers awarded a $291,773.00 contract to the URS Group of Dallas for plans and specifications for the dam restoration project.

When I attended the local ditch meeting a few years ago, the majordomo was optimistic it would soon be shovel ready and funding could be found.

He also commented on potential problems from Chimayó’s tainted ground water. People in the audience began volunteering information that people up there had put their new well next to the dam and was sucking 60% of its water from the dam they still refuse to pay for.

The 1938 Rio Grande Compact between Colorado, New Mexico and Texas limited even more the amount of water people here could use. The dam is no longer simply a source for irrigation water. It’s now part of the regional network that controls the amount and quality of water flowing to Texas.

Whatever its faults and costs, it has to be maintained.

Santa Cruz Dam History - Part 2


It’s a fact of life in northern New Mexico, there’s only so much water. Once it was allocated, and it was allocated very early, the only way left to increase agricultural production was to improve the efficiency of the acequias. In 1925, 25% of the water was lost through seepage.

In the 1930's, the Department of the Interior found the Santa Cruz ditch was poorly constructed and required 25 days every summer to maintain. If the Llanos ditch had been straightened, it would have added a square mile to the irrigated land, but landowners who were spending 45 days a summer on maintenance weren’t interested. The Puebla ditch was the worst, built though porous soil, weakened by a nearby arroyo, and requiring 30 to 50 days each summer to repair.

If the ditches couldn’t be improved, John Block reasoned the delivery system could. In 1925, he organized the commercial growers of the Española area into a conservancy district and proposed a dam. With approval guaranteed through his friendship with Tom Burns, who controlled the Rio Arriba county board of commissioners, he got a favorable engineering report from the state.

Based on 8,000 irrigated acres and a 166' dam that would hold 18,000 acres of water, they calculated it would cost $30 an acre to build. The initial tax was $0.69 an acre. They got enough people to join the conservancy to issue bonds for $250,000. Only Chimayó refused in mass, which reduced the number of acres to 5,200.

As commodity prices stayed low in the 1920's, economic conditions deteriorated for both Frank Bond and the people indebted to him. The money for the ditch tax could only come from the cash they got selling their produce to local merchants, and many were too in debt to have any. Bond moved to Albuquerque to find better opportunities near the railroad there. Louis Nohl remained in charge of the local store. W. P. Cook was a trusted assistant.


The investment broker, Sutherlin Barry Bonding Company in Los Angeles, kept 5% of the bond money for themselves, and managed to sell the bonds through their New Orleans office. It was the 1920's and everyone believed the successes of California’s inland valleys could be replicated.

The contractor, Ajax Construction of El Paso, began work in 1926, spent the money in 18 months, built about half the dam and declared bankruptcy. Two other companies put some time into the project, and each of them went bankrupt. By 1928, the annual tax was $2.69 an acre and there were some delinquencies. After some wet years, the summer of 1928 had been hot and dry.

To finish the dam, the conservancy had to issue another $250,000 in debt, sold mostly to the same investors. The tax rate for 1929 went up to $8.36 an acre, just as the national economy was crashing. A severe winter in 1928 had killed half the sheep; floods damaged land in the fall of 1929. Delinquencies soared.


Anderson Brothers of El Paso began work. The bond holders sent a representative who reported $6.00 an acre was the most they could expect the land owners to pay. They began losing money of their investment.

When the dam was completed in 1931, it cost $6,000 more than the contract. It was only 131' high and had one third the projected capacity, 6,000 acres. It had cost $95 an acre to build.

The 1929 and 1930 seasons had been wetter than normal; excess water had damaged irrigation systems. The winters of 1931-1932 and 1932-1933 were severe enough to kill livestock while the summers were so wet flooding was a problem. $40 an acre was later calculated to have been the maximum land owners could afford.

The Conservancy couldn’t pay its debts and went into receivership in 1933. Before the Reconstruction Finance Corporation would intervene, all back taxes had to be paid. The federal bank told the bond holders they would $.25 on the dollar for their original investment, with no interest. An extended drought had begun in 1932.

At this point, Hugh Calkins’ history of the dam gets vague. Some unidentified entity called the Santa Cruz Real Estate and Land Company appeared with Mr. Cook as its agent. When he couldn’t collect the unpaid taxes, he had landowners sign agreements that he would pay their taxes for them, in exchange for rights to their land.

When all the taxes were paid, the RFC took over and sent in its financial people who reported the financial affairs were “pretty much of a mess.” The land company owned 397 acres of land taken from 92 individuals who often “were unaware that their lands had been sold from under them.”


The land company had resold 180 acres to men from Oklahoma and Texas, but it was “doubtful if the money from those sales ever reached the bondholders.”

Once the RFC was in charge, the annual tax was set at $1.00 an acre in 1935 and $2.90 in 1936. Delinquencies dropped. 1934 had been another drought year, but those who still had their land believed enough water had flowed to water the gardens that fed them.

Still, the drought continued and the economy worsened. The government was employing men on its project to clear the Río Grande malaria swamps, but only Leadville was hiring temporary help. A few men went into CCC camps. According to the Department of the Interior, 51% of the men around Española were or had been on relief.

The fortunes of the Bond company faltered. According to Richard Cook, the government price for sheep was half what Bond paid for them. Both Bond and Cook senior were so heavily in debt, they offered their lands to a bank that didn’t want any more unsellable assets. Bond died in 1936, and the family sold the assets and liquidated his holding company. Cook had recovered enough to buy the Española store.

Normal rains returned in 1937.

Santa Cruz Dam History - Part 1


The Santa Cruz dam was a consequence of the Denver and Rio Grande railroad opening a station in 1881 in an area west of the Río Grande it called Española. It introduced men looking for economic opportunities into an area where local Spanish-speaking settlers saw land as their only source for food.

Surpluses moved between villages at different altitudes with different growing seasons. Truchas raised wheat, Santa Cruz grew fruit, Chimayó supplied chili, Colorado provided beans and potatoes. What cash existed came when men went to the mines in Colorado and Utah or worked as sheep herders in Colorado or Wyoming or section hands in Colorado and Arizona.

One man who followed the railroad from Pueblo, Colorado, was Frank Bond, a Canadian immigrant who had failed in the wool business there. In 1883, he bought land from the railroad for a stock shipping facility. He also opened a local store where people could pay for goods by raising sheep for him. Within a few years, most were indebted to him.

Another was Johann Block who arrived from Kansas around 1890. His father, Jacob Block, was a West Prussian who had migrated there with his family. John married Sofia Vigil Valdez and became a local landowner. His cousins, Heinrich and Jacob Jantz-johnson, also moved here; Henry was a bee-keeper, Jake a dairy man.


When war broke out in Europe in 1914, England could no longer import food from Russia and Germany. Prices rose in this country, even in the Santa Cruz valley. W. P. Cook came in 1915 and started work for Frank Bond as a stable boy.

Prices fell as soon as the war was over, and stayed depressed through the 1920's. Commercial farmers like to think the war years were the new normal and the present was an anomaly. One way to address it was produce more, and over-production throughout the decade kept commodity prices low nationally.

The new men weren’t deterred by the fact the easiest land to farm was taken. They believed all you had to do to make dry land productive was add water. In 1919, the commercial farmers petitioned the courts to revisit the distribution of water.


They didn’t understand demand for that water was already increasing. 1917 and 1918 had been dry years. The local population hadn’t been able to send its young to settle the frontiers after the United States took control of the land east of the Sangre de Cristo. Chimayó was taking more of the water before it could reach the valley. The court ruled in Chimayó’s favor.

Then, a man named Conger wanted to bring more land into production by building a 14 mile ditch from the Río Grande. The years between 1920 and 1925 were drought years in the state. When the ditch was completed in 1924, farmers turning chili into a commercial crop in the Mesilla Valley in the southern part of the state successfully protested the diversion of common water.

The Ditch - The Dam


The Santa Cruz dam sits near the edge of an uplift of Mesoproterozoic granite topped by early Pleistocene sandy gravel.

Daniel Koning’s geological map for the Cundiyo quadrangle shows the uplift lies between two north-south faults with the western one through the reservoir and the eastern roughly along route 503. Both are moving east. Between them, northeast of the lake, is another, shorter fault that curves and is moving northeast.

The sedimentary land at the top of the dam basin is 6300'. The structural and hydraulic heights of the dam are 151' but only 100' is available to hold water. The width of the dam at its base is 103.6'. That means the crack in the uplifted rock, at its narrowest, is something like 150' x 100'.


The lake covers 121 acres at the top and looks to be roughly 4000' long from the face to the point where the bowls narrows and water is white in the picture below. The opening widens to 600' in places.


From there the Santa Cruz river runs for a mile to the point it forms at route 503. It first goes south where the land above is 6400', then curves to go northeast where the surface land is 6600'. It flows through what Craig Martin describes as a “narrow, rocky canyon.”


The 10' to 15' wide river has “shallow runs and many holes 4 to 10 feet deep” for brown trout. That means, the the crack goes more than 10' below the surface and the river bottom is rock fill.


Martin say’s it’s possible to walk the river, nearly to the dam, if you’re willing to wade through the water and navigate those openings.

You don’t need to venture so far to see the rocks that form the walls of the reservoir. They’re visible on route 503 where the river begins it narrow journey. Daniel Koning says the granite and granitic pegmatite have a “distinct reddish weathered surface” and consist of potassium feldspar, quartz, muscovite, plagioclase feldspar and biotite.


Outcrops can also be seen when you follow the river back from route 520 to the dam at the northern end of canyon fault.


The Bureau of Reclamation says that the “quality designations” of the dam’s supporting rock “ranged from poor to very poor; however, with depth the fractured zones are locked in and will provide adequate foundation.”

That’s as reassuring as it gets in an area striped with faults. A collapsed dam would spread disaster all the way to the Rio Grande.
