A foxtrot called "Boegoeberg's Dam" was popular in the workers' camp during the early 1930s. The men who danced to it were not professional builders. They were unemployed South Africans recruited under a Great Depression make-work program, hauling concrete and laying stone in the Karoo heat for seven shillings and sixpence an hour, building a dam they hoped would deliver them farms, factories, and houses. Some wrote poetry about those hopes. The dam they built still stands on the Orange River near Prieska, and the canal it feeds still irrigates the land.
The idea of irrigating the lower Orange River predated the dam by decades. In the 1890s, a man named Litchfield set up a hydroelectric generator and pump on the river, recognizing the potential of the fertile banks where farmers had been hauling water by hand since 1872. Litchfield proposed a public irrigation scheme in 1895. Nobody listened. In 1902, a Cape Colony engineer named W.D. Gordon endorsed the proposal. Nobody listened again. It took until February 1911, when Alfred Dale Lewis -- a section engineer with the Cape Town Department of Irrigation who would later serve as South Africa's national director of irrigation from 1921 to 1941 -- conducted a detailed survey of the lower Orange, mostly on foot and partly by horse-cart. Historian T.V. Bulpin wrote that Lewis's struggles through severe heat and inhospitable terrain are unsurpassed in the annals of scientific research in South Africa. Lewis recommended a dam near Boegoeberg and a 130-kilometer canal to supply 4,000 acres of irrigable land.
Budget problems shelved the plan for years. What revived it was not engineering ambition but human desperation. The Carnegie Commission of Investigation on the Poor White Question in South Africa identified irrigation construction as a way to provide both immediate employment and long-term land settlement for impoverished white South Africans. The Department of Labour launched the project, and work began on May 23, 1929. The first task was a 622-meter-long, 10-meter-high retaining wall at Zeekoe Baard's Drift. Workers raised 68 sluices to filter floodwater and capture silt, directing water to a canal and reservoir system that could draw from the river all the way up to Augrabies Falls. A camp rose at the isolated site: tents, huts, a school, a clinic, and stores to keep 250 married laborers and their families alive in a place where nothing grew without help.
The laborers were supervised by engineers including Adolf Aslasksen, Sven Eklund, Gordon Allen, and D.F. Kokot, but the tone of the camp was set by the workers themselves. They wrote poetry about the future they were building. They danced. The foxtrot "Boegoeberg's Dam" became a camp anthem, a song about a concrete wall in the middle of nowhere that somehow carried the weight of aspiration. The conditions were brutal -- Karoo heat, isolation, hard physical labor -- but the workers understood that what they were constructing was not just a dam. It was a claim on the land, a pathway out of poverty, and for some, it was literally a home. When the dam was finished in 1933, many of them stayed.
In 1934, the first water flowed through the 121-kilometer canal to 6,600 hectares of land divided into 5-hectare plots, each with a stone house built on it. The opening ceremony featured speeches, prayers, and a braai. Every attendee was asked to contribute a stone to a workers' memorial. The memorial was not built immediately. On December 16, 1938, when ox-wagons celebrating the centennial of the Great Trek reached Pretoria to lay the cornerstone for the Voortrekker Monument, it was decided to build the Boegoeberg Dam memorial from those original stones, commemorating both the dam and the Trek. The town of Groblershoop was founded in 1936 on land that had been called Sternham, named after P.G.W. Grobler, Minister of Lands in the Hertzog cabinet from 1924 to 1933.
Boegoeberg takes its name from Croton gratissimus, a small tree also called Bergboegoe, which grows on the hillsides near the dam site. The word is Afrikaans, rooted in the buchu plant that has been used in traditional medicine by the Khoisan people for centuries. The dam itself is a gravity-type structure, relying on its own mass to hold back the Orange River. Its primary purpose remains irrigation, and its hazard potential is rated low -- a modest assessment for a structure that transformed a stretch of desert into farmland and a workers' camp into a town. The reservoir has since become a gathering spot for swimming, water sports, and angling, and an RV park draws travelers who stop to fish the same waters that once seemed impossibly beyond reach.
Located at 29.04S, 22.20E on the Orange River near Prieska in the Northern Cape, South Africa. The dam and its 121 km irrigation canal are visible from altitude, with the irrigated farmland appearing as a green ribbon along the river contrasting with the brown Karoo. The town of Groblershoop lies downstream. Nearest major airport is Upington (FAUP), approximately 200 km northwest. The dam structure itself is relatively modest in size but the canal system is extensive.
