Tulsa completes Spavenaugh Water Project transforming city’s water supply in 1924

On May 2, 2025, the Tulsa Women's Commission convened to discuss the ongoing impact of historical infrastructure projects on the community, with a particular focus on the Spavenaugh Water Project, which celebrated its centennial this year. This ambitious initiative, launched in 1924, aimed to provide clean and reliable water to Tulsa, transforming the city’s water supply system.

The Spavenaugh Water Project was a response to the inadequate water sources available at the time, which included springs, wells, and the polluted Arkansas River. The project was spearheaded by civil engineer W. R. Hallway, who confirmed the feasibility of transporting water from the crystal-clear Spavenaugh Creek to Tulsa through gravity flow. The citizens of Tulsa overwhelmingly supported the project, passing a $6.8 million bond issue to fund it.

Construction of the Spavenaugh dam, which took two years and cost $7.5 million, resulted in the creation of Spavenaugh Lake, the largest lake in Oklahoma at the time. The dam is notable for its impressive dimensions—two-thirds of a mile long and five stories high—impounding 8.5 billion gallons of water. The original pipeline, stretching 54 miles, was the longest raw water line in the United States upon completion, showcasing significant engineering achievements of the era.

The completion of the Spavenaugh water system was celebrated on November 17, 1924, marking a pivotal moment in Tulsa's history. The project not only provided a reliable water source but also laid the groundwork for future growth and development in the region. Today, Tulsa delivers an average of 105 million gallons of award-winning water daily to over 650,000 residents.

During the meeting, members of the Tulsa Women's Commission reflected on the historical significance of the Spavenaugh Water Project, emphasizing its role in shaping the city’s future. The discussions highlighted the importance of infrastructure in community development and the ongoing need for sustainable water management practices.

As Tulsa continues to grow, the legacy of the Spavenaugh Water Project serves as a reminder of the critical role that innovative infrastructure plays in supporting the needs of the community. The commission plans to further explore how historical projects can inform current and future initiatives aimed at enhancing the quality of life for all Tulsans.
