Prior to local and federal efforts in the mid-twentieth century to control rivers through the construction of dams, the Brazos River routinely overflowed its banks. In 1913, the most violent flood to date overwhelmed East Waco, taking two lives and destroying numerous houses and businesses. This, combined with other disastrous floods throughout the nation, spurred a movement to harness the powerful force of the river.

In 1923, the Texas State Legislature conducted a flood control study which recommended the creation of a state agency with the power to carry out the tasks necessary to curb the destruction of the Brazos River. In 1929, the state formed the Brazos River Conservation and Reclamation District. That same year, after much local debate, a small dam on the Brazos River was constructed. This dam primarily provided the city with a constant water supply, though it also offered minimal amounts of flood protection.

Rain fell heavily throughout Central Texas in 1936. In September, a torrential downpour filled the Brazos River to record levels, cresting at 41 feet. The surging river proved to be too much for the small protective measures taken for the city. About one mile north of Waco, the river burst through a levee and flooded into the city.

The river rose to just a few inches below the floor of the Washington Avenue Bridge and the Suspension Bridge and overflowed its banks, overwhelming East Waco. Although no lives were lost, the flood resulted in approximately $1.5 million worth of property damage and left two thousand residents homeless. In order to restore order and begin the process of rebuilding, city manager W. C. Torrence declared martial law in the flooded area.

As Torrence appealed to citizens for monetary relief for flood victims, Congressman Bob Poage appealed to the federal government for help in taking more serious protective measures for the city. In 1937, the US Army Corps of Engineers conducted a study which recommended the construction of a series of dams on tributary streams of the Brazos River. This ultimately led to the construction of the Lake Whitney and Lake Waco Dams, which today protect the city from disasters such as the 1936 flood.

Throughout its history, Waco has been affected by a constant cycle of drought and flooding due to its prime location near several major rivers. The construction of Lake Waco Dam was one of the most successful efforts to address these issues, providing the city with flood protection and a stable water supply.

Many Wacoans, including Mayor H. F. Connally, opposed the construction of the original dam in the 1920s, preferring to rely upon the city’s artesian wells as a water supply. Though some saw the dam as a foolhardy and risky luxury, the city put the issue up to a vote in 1926 after the wells began to run dry. Voters approved the construction of the dam by a slim margin of just over one hundred votes. In 1929, Callahan Construction Company completed work on the dam on the Bosque River.

The small dam, though beneficial to Waco, proved to be insufficient to protect the city from severe flooding. After a record flood in 1936 submerged East Waco and displaced two thousand people, Congressman Bob Poage received authorization for a US Army Corps Engineering flood control study of Lake Waco. The results of the study in 1938 recommended an enlarged Lake Waco with a bigger, more modern dam.

However, the onset of World War II put the Lake Waco project on hold for some time. The construction of dams on Lake Whitney and Belton Lake took precedence in 1946, though the need for a larger water supply was becoming more apparent each year. Several Wacoans appealed to the federal government for funding, and in 1954, Congress authorized the construction of a new dam in order to lessen the flood threat to the city of Waco and provide more efficient water storage.

As the US Army Corps of Engineers began to design the new dam, Central Texas conditions worsened. The most severe drought of the twentieth century struck Texas in the 1950s. The period saw all but ten of Texas’ counties declared federal disaster areas, and in Waco, despite efforts to ration and conserve water, taps ran dry and factories slowed production. Additionally, the water supply in Lake Waco was hampered by the buildup of silt from farming up river.

A second disastrous flood hit the city in April 1957, reenergizing efforts to complete the dam. The Brazos River Authority and the city offered to provide a loan to the federal government in order to begin construction on the dam quickly. After some negotiations, President Eisenhower included one million dollars in his proposed budget for the construction of the new dam.

In the weeks following the dam’s completion in the fall of 1961, engineers detected a problem with disastrous implications. Cracks appeared in the eastern face of the dam and slowly began to spread. Soon, a portion of the east side fell sixteen feet, sliding downstream. The US Corps of Army Engineers quickly discovered the problem was a layer of compressed shale in the ground which the weight of the dam had pushed out. They modified and stabilized the dam, completely finishing construction in the spring of 1965.

Army engineers and the city of Waco agreed to raise the level of the lake seven feet in 2003 in order to provide a more secure source of water for Waco and surrounding municipalities. Waco civic leader Jack Kultgen described the dam as the “single biggest factor in the progress of Waco” in the twentieth century because it gave Waco an advantage over many other Central Texas cities. The Lake Waco Dam provides the city with a constant source of water, ensuring the city’s ability to grow in spite of weather conditions.
