Rushcreek Structure No. Iii-a

About Rushcreek Structure No. Iii-a

The primary purpose of Rushcreek Structure No. Iii-a 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 Rushcreek Conservancy District (local government). It impounds the Tributary To Center Branch Rush Creek near Carthon.

The dam stands 34 feet tall and stretches 700 feet across, creates a reservoir covering 12 acres, has a maximum storage capacity of 415 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1969, 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 04/26/2022.

At 34 feet, this dam is taller than 80% of dams nationwide.
