About Lake Bastrop Dam
The primary purpose of Lake Bastrop Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Lower Colorado River Authority (local government). It impounds the Spicer Creek near Bastrop.
The dam stands 88 feet tall and stretches 4,000 feet across, creates a reservoir covering 244 acres, has a maximum storage capacity of 24,700 acre-feet, and collects water from a drainage area of 8 square miles. Completed in 1964, 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 11/17/2022.
At 88 feet, this dam is taller than 97% of all dams in the United States.
