About Langston Lake
The primary purpose of Langston Lake is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by Langston University (state). It impounds the Tributary To Fitzgeral Creek near Langston.
The dam stands 65 feet tall and stretches 2,500 feet across, creates a reservoir covering 420 acres, has a maximum storage capacity of 7,720 acre-feet, and collects water from a drainage area of 6 square miles. Completed in 1966, 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 01/31/2022.
