International Speedway

About International Speedway

The primary purpose of International Speedway 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 Kansas Dept Of Transportation (state). It impounds the Little Turkey Creek-tr.

The dam stands 35 feet tall and stretches 282 feet across, has a maximum storage capacity of 448 acre-feet, and collects water from a drainage area of 1 square miles.

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. An emergency action plan is in place for this dam. The most recent inspection on record was 04/28/2023.

At 35 feet, this dam is taller than 82% of dams nationwide.
