About Davids Creek Watershed Site 1b-2

The primary purpose of Davids Creek Watershed Site 1b-2 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 Audubon County Swcd (local government). It impounds the Tr-davids Creek near Exira.

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 08/30/2023.

At 45 feet, this dam is taller than 91% of dams nationwide.
