In 1909 the company Agricola Force SE Electrica del Rio Conchos won the contract to use the water of Rio Conchos for power generation. A dam was started in 1909, but as a result of the Revolution, work was suspended until 1916. A hydroelectric plant was built at the base of the dam. Shown are views of the dam from above and below; the exterior of the hydroelectric plant; interior views showing massive machinery, and the huge tunnel used to channel water.
