Hess Dam, located in Lake Panorama, Iowa, is a privately owned earth dam that serves multiple purposes including fire protection and providing water for livestock and small fish ponds. Built in 1967 by the USDA NRCS, this dam stands at a height of 21 feet and spans 450 feet in length, with a storage capacity of 60 acre-feet. Despite its age, the dam is considered to have a low hazard potential and a moderate risk assessment rating of 3.

The dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections, although the last recorded inspection was in June 1986. While it has not been rated for its current condition, the dam's risk management measures and emergency action plan status are unknown. The dam's primary purpose and design make it an important water resource for the area, providing essential services for both fire protection and agricultural needs.

With its location on the TR-Middle Raccoon River and its association with the Natural Resources Conservation Service, Hess Dam plays a critical role in managing water resources in Guthrie County, Iowa. As a vital component of the local ecosystem, it is important that the dam continues to be maintained and monitored to ensure its safe operation and overall effectiveness in serving the community's water needs.
