poured the first concrete. The project eventually used 3 million cubic yards of concrete. Engineers adopted air-entrained concrete to reduce the effect of freeze-thaw cycles and to make the material more stable and workable. They also incorporated fly ash into the concrete mix. Hungry Horse was the first dam built with these innovations. The construction claimed the lives of 23 men.

However, no irrigation facilities were built and the project has no irrigation obligations. Hydroelectric power generation and flood control are the primary purposes of the dam. The dam, reservoir, and surrounding area are used for recreation.

At 564 feet (172 m) in height, the dam was the third largest and second highest concrete dam in the world at the time of its completion in 1953, with a volume of 3,100,000 cubic yards (2,400,000 m). The dam's spillway is the highest

Power generating facilities at Hungry Horse Dam are housed in a building constructed across the river channel at the downstream toe of the dam. The original design included four 71,250-kilowatt generators—a total of 285
