🇦🇷 Argentina · Córdoba
Villa del Dique and the neighboring town of Embalse sit in the south of the Valle de Calamuchita, looking out over the great Embalse de Río Tercero, the largest artificial body of water in Córdoba province. Here the draw isn't so much the sierra rivers as the lakeshore: beaches, water sports, fishing and sunsets over the water, in a setting of hills and quiet.
The Embalse de Río Tercero, created by a dam built between 1927 and 1936 for hydroelectric power and flow control, transformed the landscape of the valley: its 5,600 hectares of water make it the largest body of water in Córdoba. Villa del Dique, founded in 1935 on its shore, offers beaches, beach clubs and a serene atmosphere, while the town of Embalse adds its own waterfront, the historic Unidad Turística from the Perón era and an identity tied to the dam and the nuclear plant.
This guide covers the essentials of Villa del Dique and Embalse from a practical angle: the shore and beaches of the lake, water sports and fishing, the sierra surroundings and the closeness of the big Calamuchita destinations, and how to get around this lakeside corner of southern Córdoba.
The Valle de Calamuchita region was inhabited by the Comechingones and, in colonial times, organized itself around rural estancias. The great milestone that shaped today's landscape was the construction of the Río Tercero dam (1927-1936), which created the largest artificial lake in Córdoba. Villa del Dique was founded on its shore in 1935, and in the years of the first Peronist government the Unidad Turística, an icon of Argentine social tourism, was built in Embalse. The full story is on our history page.

Origins, formation and what the sources say.
The largest lake in Córdoba didn't exist a hundred years ago. Where thousands of tourists now spend the summer, sail and fish for pejerrey, the Río Tercero simply ran between estancia fields, and nobody would have imagined that a dam was going to flood the valley to create, out of nothing, one of the most visited destinations in the Argentine interior. That's the first surprise about Villa del Dique and Embalse: the landscape that defines them is, literally, younger than many of their own residents.
Before the great lake existed, the south of the Valle de Calamuchita was a country of hills, rivers and fields, inhabited in pre-Hispanic times by the Comechingones, the indigenous people of the Córdoba hills. As in the rest of the valley, these communities lived from farming, hunting and gathering, in close relationship with the Río Tercero (Ctalamochita, in its indigenous name, which means roughly 'salty river' or refers to its course) and its surrounding hill woodland.
Through the colonial period and the centuries that followed, the region organized itself around estancias and rural activity, with a scattered population given over to the land, small livestock and some dry farming. The Río Tercero, one of the main watercourses in the province, crossed the valley bringing life and resources, but also causing periodic floods in times of heavy rain that hit the riverside settlements hard.
The area where Villa del Dique and Embalse now stand was, then, a rural valley landscape dotted with estancia houses and country chapels, very different from today's lakeshore profile of marinas, beach clubs and hotels. The great transformation would come only in the 20th century, with an engineering work colossal for its time that would change the face and the fate of this whole part of the valley forever: the construction of the dam on the Río Tercero.
The milestone that shaped the landscape and the present-day fate of Villa del Dique and Embalse was the construction of the Río Tercero dam, a story that began much earlier than most people imagine: the foundation stone was laid on 10 December 1911. That first project, English in inspiration, was halted by the First World War, and work only resumed in 1927, by then under the direction of the Argentine engineers Santiago Enrique Fitz Simon and Juan Carlos Alba Posse, who redesigned and enlarged the original dam. The main wall, built in granite, reached 50 meters high and 360 meters long, complemented by a 300-meter spillway, a 900-meter auxiliary earth dam and a 40-meter hydroelectric powerhouse tower. By 1936 the whole thing was finished: the largest artificial body of water in Córdoba province had been born.
The dam was conceived to generate hydroelectric power, control the floods of the Río Tercero —which periodically battered the riverside settlements downstream— and guarantee water for irrigation and industry. But its most visible effect was on the landscape: the impounded water flooded fields and low ground in the valley and created a vast lake surface ringed by hills, an 'inland sea' where before there had only been estancias.
The new lake changed the human map of the area. The town of Embalse, whose name refers directly to the dam, grew up around the works and their upkeep. And on the northern shore of the lake, on 11 October 1935, Mateo Osella and Enrique Marandino founded a summer resort they called, with crushing logic, Villa del Dique: a town born explicitly to make the most of the brand-new sheet of water, one of the few Argentine cases of a tourist settlement created almost at the same time as its own attraction. The dam didn't just do its energy job: it opened up, without entirely meaning to, the vocation that defines the whole area to this day, lake tourism.
If the dam created the lake, it was the first Peronist government that turned it into a national symbol. Between 1946 and 1951, as part of the First Five-Year Plan, Juan Domingo Perón's government built the Unidad Turística Embalse on the reservoir's shore, a monumental social tourism complex designed so that Argentine workers —who for the first time had mass access to paid holidays— could take a summer break at subsidized prices. The first hotels, No. 1 and No. 2, opened in 1947; by 1951 the complex comprised 7 large hotels, 51 bungalows, a chapel, a pool, a medical service, shops and a water tower that doubled as a lookout, all set in parkland facing the lake.
Along with its twin complex at Chapadmalal, on the Buenos Aires Atlantic coast, Embalse became the definitive image of 'holidays for everyone': trains packed with working families arriving from all over the country, union groups and, decades later, entire generations of students on their graduation trips. Hundreds of thousands of Argentines passed through its rooms who, without the social tourism policy, would hardly have seen the Córdoba hills. In 2013 that historical value was officially recognized: the complex was declared a National Historic Monument by decree 784/2013.
Recent history has added an uncertain chapter: in 2026 the national government took the Unidad Turística out of the social tourism program and cleared the way for its sale, closing —at least for now— an era of almost eighty years. The hotels stopped taking groups, though the architectural complex, with its imposing 40s style facing the water, is still standing and can be taken in from outside. For the curious traveler, walking around it is a glimpse of one of the most ambitious social experiments in Argentine history, frozen on the shore of the lake.
With the creation of the great lake, the south of the Valle de Calamuchita found a new tourist identity, different from that of the river towns in the rest of the valley. The lakeside settlements —Villa del Dique, Embalse and others— gradually turned into lakeshore destinations, making the most of the beaches, the calm water and the sierra landscape that frames the reservoir.
The lake became one of the main water-sports centers in the Argentine interior, with sailing, windsurfing, kayaking and boating in the lead, and also a sport fishing destination. Yacht clubs, beach clubs, hotels, cabins and campsites appeared, and the area joined the tourist circuit of the Valle de Calamuchita, one of the most visited in Córdoba.
Today Villa del Dique and Embalse offer visitors a lakeside break: beaches and promenades for the summer, water sports, fishing, sunsets over the water and the calm of hill towns. Being close to destinations such as Santa Rosa de Calamuchita and Villa General Belgrano lets you combine the lakeshore with the rivers, the towns and the rich offering of the valley, in a region that managed to reinvent itself off the back of a major engineering work.
The layout of Villa del Dique itself tells that story: its streets run down towards the shore, organized around the various beach clubs and clubs that appeared from the middle of the 20th century on, when the first Córdoba families began building weekend houses facing the water. That spontaneous growth, typical of Argentine summer towns, gave the villa an informal, homely character it still keeps, very different from the more planned real-estate developments on other tourist coasts in the country.
Southern Calamuchita's energy vocation didn't end with the hydroelectric dam. In the 1980s, on the shore of the Embalse de Río Tercero lake, the Embalse Nuclear Power Plant came on stream, Argentina's second nuclear power station, opened in 1984. The project used lake water to cool its reactors and confirmed the region as a national-scale energy production hub.
The plant's arrival transformed life in the area once again: it created jobs, drew in technical and specialized workers, and reinforced the character of the town of Embalse as a place tied to major energy projects. Decades later, the plant went through an extensive refurbishment to extend its working life, which stirred the local economy all over again. Hydroelectric power first and nuclear power afterwards thus shaped the productive identity of this corner of the valley.
For visitors, this energy dimension sits alongside the tourist one without overshadowing it: the lake remains, above all, a destination of beaches, water sports and rest. But knowing the history of the dam and the plant helps explain why Villa del Dique and Embalse have the profile they do, and how a succession of major engineering works ended up drawing the landscape and the economy of southern Calamuchita.
