The Act That Made Lake Texoma

June 28, 1938. Congress signed the Flood Control Act — and in doing so, set in motion one of the most consequential land and water projects in Texas history.

The Red River had been flooding the Texas-Oklahoma border for generations. The 1908 flood was particularly brutal, wiping out communities and farmland up and down the valley. By the 1920s, it was clear that seasonal destruction wasn't a weather problem, it was an engineering problem.

George Moulton, a Denison businessman, had been saying so since 1925. He envisioned a dam at Baer's Ferry on the Red River and spent years lobbying chambers of commerce on both sides of the state line. It took a decade of persistence and the right man in Washington.

Sam Rayburn of Bonham, Texas, was one of the most powerful men in Congress. He would go on to become Speaker of the House — longer than anyone in history. In the early 1930s, he was instrumental in pushing the Denison Dam project through the legislative process.

When the Flood Control Act was signed on June 28, 1938, it authorized construction of the dam for three purposes: flood control, hydroelectric power, and water supply. Rayburn's influence had made it possible.

Construction began August 22, 1939, the same year World War II started in Europe, the same year The Grapes of Wrath was published. The timing wasn't ideal, but it wasn't accidental either. The tail end of the Great Depression meant hundreds of men needed work, and the Army Corps of Engineers put them to it.

The dam was completed in February 1944, at a total cost of $54 million; that's roughly $1 billion in today's dollars. At the time, it was the largest rolled earth-fill dam in the United States — 15,350 feet long and 165 feet high. The first hydroelectric turbine came online in March 1945.

Lake Texoma sits on the Red River between Grayson and Cooke counties in Texas and four counties in Oklahoma. It covers 89,000 acres. Today it ranks among the 12th largest reservoirs in the entire U.S. Army Corps of Engineers system.

It has filled to full pool only three times in its history: 1966, 1990, and 2007.

For the land along its shores — ranches, recreational properties, waterfront acreage — the lake reshaped everything. What had been flood-prone bottomland became some of the most sought-after real estate in North Texas.

Water and land are inseparable in Texas. Where rivers run, towns formed. Where dams were built, lakes were born — and with them, entirely new land markets.

Lake Texoma is a reminder that the Texas landscape we know today wasn't always inevitable. It was engineered, advocated for, and built by people who saw what the land could become.
