Simonson Dam, located in Emmetsburg, Iowa, is a privately owned structure designed by the USDA NRCS for fire protection, stock, and small fish pond purposes. Built in 1965, the earth dam stands at 24 feet high and spans a length of 415 feet, with a storage capacity of 61 acre-feet for its 3.1-acre surface area. Situated on TR-Drainage Ditch 132, the dam is regulated by the Iowa DNR and falls under state jurisdiction for permitting, inspection, and enforcement.
With a low hazard potential and a moderate risk assessment, Simonson Dam has not been rated for its condition but is deemed to meet guidelines for emergency action planning. While lacking in updated inspection records and emergency contact information, the dam serves its intended purposes effectively and stands as a vital water resource in Palo Alto County. Managed by the Natural Resources Conservation Service, the dam contributes to local water management efforts within the Rock Island District, providing essential services to the surrounding community while maintaining a safe operational status.
