Walters Creek Watershed Site 22-1 is a vital water resource in the state of Iowa, located in Adams County near the city of Nodaway. This site, managed by the local government, serves multiple purposes including fire protection, livestock watering, and small fish pond maintenance. Constructed in 1968 by the USDA NRCS, this earth dam stands at a height of 29 feet, with a length of 745 feet, and a storage capacity of 170 acre-feet.

With a low hazard potential and a moderate risk assessment, Walters Creek Watershed Site 22-1 is regulated by the Iowa DNR and undergoes state permitting, inspection, and enforcement. The dam's primary purpose is flood risk reduction, which is crucial for protecting the surrounding area from potential inundation. Despite its importance, the condition of the dam has not been rated, highlighting the need for regular assessment and maintenance to ensure its continued effectiveness in managing water resources in the region.
