Pearson Dam, located in Augusta, Iowa, was completed in 2006 and serves multiple purposes, including fire protection and creating a small fish pond. The dam, designed by NRCS, is privately owned and regulated by the Iowa DNR. With a height of 27 feet and a length of 367 feet, Pearson Dam has a storage capacity of 61 acre-feet and a surface area of 4.1 acres.

The dam, built on Prairie Creek, has a low hazard potential and is classified as having a moderate risk level. It has an uncontrolled spillway and is primarily made of earth with a soil foundation. The dam's condition is currently not rated, and it does not have an Emergency Action Plan in place. While the dam does not have associated locks or outlet gates, it has undergone state inspections and is permitted and regulated by the Iowa DNR.

Pearson Dam is a significant water resource in Henry County, Iowa, providing valuable water storage and recreational opportunities for the local community. While the dam's risk level is moderate, it continues to be a vital structure for fire protection and stock management in the area. As climate change impacts water resources, Pearson Dam plays a crucial role in managing and conserving water for future generations.
