Delaney Creek Dam No. 1

About Delaney Creek Dam No. 1

The primary purpose of Delaney Creek Dam No. 1 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 Delaney Creek Conservancy District (local government). It impounds the Unnamed Tributary Delaney Creek near Kossuth.

The dam stands 59 feet tall and stretches 740 feet across, creates a reservoir covering 27 acres, has a maximum storage capacity of 1,390 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1971, 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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 09/14/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.

At 59 feet, this dam is taller than 95% of all dams in the United States.
