Harsha Dam, located in Kellogg, Iowa, was completed in 1975 by the USDA NRCS and is privately owned. The dam serves multiple purposes including fire protection, stock, small fish pond, and recreation. With a height of 28 feet and a length of 300 feet, the dam has a storage capacity of 79 acre-feet and covers a surface area of 4.2 acres.

The dam is regulated by the Iowa DNR and is considered to have a significant hazard potential. Although the condition assessment is not rated, the risk assessment is moderate. The spillway type is uncontrolled, and the dam is primarily constructed of earth with a soil foundation. The dam is situated on the TR-Slater Creek and falls under the jurisdiction of the Rock Island District. The last inspection date was in July 1977.

For water resource and climate enthusiasts, Harsha Dam offers a fascinating study in dam construction and operation. Its multi-purpose design highlights the importance of water management for fire protection, agriculture, and recreational activities. With its moderate risk assessment and significant hazard potential, this dam serves as a reminder of the critical need for proper maintenance and oversight in managing water resources in the face of changing climate conditions.
