. Ellis made Norfork Dam his personal project and fought for it until construction began in the spring of 1941. Having won the election with the promise of cheap hydroelectricity
, he hoped the dams would give rise to industry and lift the region out of the depths of depression. Ellis firmly believed that if Norfork Dam was built then the other dams would follow. Authorization for construction of the dam was included as part of the flood control act of June 28, 1938. Norfork Dam was to be one of six dams built to accomplish flood control in the White River
basin. The act was later revised in 1941 to include Bull Shoals
and Table Rock

to insist that power generation be included in the project purpose. The Baxter County delegation wanted to pass a resolution that would have expressed opposition to any dam that did not include hydroelectric power facilities. They feared that the cost/benefit ratio would not justify congressional expenditure unless power generation was included, and the dam would never be built. However, the Batesville, Arkansas
delegation was able to convince the assembly that the resolution may be interpreted as general opposition to the dam and it never passed. They believed that the population and economic growth brought by the construction of the dam would make it feasible for power companies to move in. As it happened the citizens of Baxter County need not have worried. Shortly after construction began Congress, under the threat of impending war, authorized construction of the power house and two out of the four generators for Norfork Dam (Messick).
, Norfork Dam was one of the six largest concrete dam
s in the country at the time of its construction. All preliminary investigation, the final design of the structure, and the preparation of construction plans and specs was carried out under the supervision of Lieutenant Colonel Stanley L. Scott. Much work had to be done before construction could begin on the massive structure. First, a suitable location had to be found before any other type of work could begin. Because of the large number of caves in the region foundation exploration, using diamond tipped drills, was carried out for nearly a year before plans were completed. Once a site was selected, a nearby source of sufficient materials for construction had to be located. Since the site was acceptable for either an earth or concrete dam, the types of construction materials and their locations would be the deciding factor in determining what type of dam would be built. The decision to build a concrete dam was made because sufficient quantities of concrete aggregate could be located near the construction site, while there was insufficient material for an earth dam. The detailed design of the dam, construction plans and specifications were prepared by the design section of the engineering division under Mr. G.R. Schneider.
The construction contracts for the dam were awarded to the Morrison-Knudsen company and the Utah Construction Company. Both companies had participated in the construction of the Grand Coulee Dam
and Hoover Dam
. Construction began in the spring of 1941 with the removal of 400000 cubic yards (305,821.9 m³) of earth to expose the bedrock foundation and an additional 28000 cubic yards (21,407.5 m³) had to be removed to stabilize it. This was accomplished using draglines and power shovels. Most of the smaller aggregate used in construction was removed from the sand and gravel bars of a twenty mile (32 km) section of the White River. A quarry and crushing plant was required to create nearly 800,000 tons of larger aggregate. Between thirty-five hundred and four thousand people came to witness the first blast to be made on Norfork Dam. Touted by advertisers as the biggest blast in the world; many of the spectators were sorely disappointed when the blast finally occurred. They had been made to believe that the entire cliff was going to be blown away. After the event, construction officials said no one had ever intended to do this and apologized for the disappointment (Blevins; Scott).
Norfork Dam is a gravity dam; this means that it resists the thrust of water entirely by its own weight. This take enormous amounts of concrete which can be expensive; however, many engineers prefer the solid strength of gravity dams to arch dam
s or buttress dam
s. For example Norfork Dam and the powerhouse cost approximately 28,600,000 dollars; a very large sum of money in the early 1940s. It was constructed in sections, called monoliths, ranging from forty to fifty-four feet in length and not exceeding five feet in height (Scott).
The completion of the dam had an immediate effect; with freedom from the fear of floods many people began to reoccupy farms downstream of the dam. Ironically the areas most affected by seasonal flooding were those covered by the reservoir, and the dam had little effect on flooding of the White River. However, not everyone was happy with the construction of the dam, nearly four-hundred people had to be removed from one of the most heavily populated and prosperous regions of Baxter County to make room for the reservoir. The government only paid people for their land if they had structures on it. As a result many people did not get paid for their land when it was covered. In fact, one man who thought he had lake front property paid taxes on it until 2004 when he realized that his property was underwater (Andrewson).
Most of the lake lies within Baxter County, Arkansas
, with its Northernmost portion in Ozark County, Missouri

Bass

Power generation
Power generation was not originally included in the project purpose for Norfork Dam. However, this was unacceptable to the people of Baxter County and the surrounding region. The sparse population of the area did not justify investment, by private companies, in a large network of power lines.
