About Indian Creek Watershed Site 2

The primary purpose of Indian Creek Watershed Site 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 West Pottawattamie County Swcd (local government). It impounds the Indian Creek near Council Bluffs.

The dam stands 65 feet tall and stretches 2,000 feet across, creates a reservoir covering 28 acres, has a maximum storage capacity of 767 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1975, 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 08/10/2023.

At 65 feet, this dam is taller than 96% of all dams in the United States.
