About Gasburg Creek Dike
The primary purpose of Gasburg Creek Dike is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Turlock Irrigation District (public utility). It impounds the Tuolumne River near La Grange.
The dam stands 75 feet tall and stretches 1,040 feet across, creates a reservoir covering 1 acres, and has a maximum storage capacity of 1 acre-feet. Completed in 1971, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 07/06/2023.
At 75 feet, this dam is taller than 97% of all dams in the United States.
