Gardner Lake Dam

About Gardner Lake Dam

The primary purpose of Gardner Lake Dam 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 Gardner, City Of (local government). It impounds the Kill Creek near Desoto.

The dam stands 61 feet tall and stretches 1,550 feet across, creates a reservoir covering 130 acres, has a maximum storage capacity of 3,618 acre-feet, and collects water from a drainage area of 5 square miles. Completed in 1940, the structure is well-established, with more than 75 years of service.

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 12/09/2021.

At 61 feet, this dam is taller than 95% of all dams in the United States.
