About Indian Creek Watershed Site 2
The primary purpose of Indian Creek Watershed Site 2 is flood risk reduction.

The dam is owned by West Pottawattamie County Swcd (local government). It impounds the Indian Creek near Council Bluffs.

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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam.
