While it does not have a designated emergency action plan (EAP) or detailed risk management measures in place, the structure meets state guidelines and is subject to regular state enforcement and inspection.

Water resource and climate enthusiasts intrigued by the engineering and management of dams will find Shelton Dam a fascinating case study. From its construction by the Natural Resources Conservation Service to its current operation and maintenance, this structure offers insight into the complexities of managing water resources for various purposes while balancing safety and environmental concerns. With its location along the TR-Wolf Creek and proximity to the Rock Island District, Shelton Dam presents an opportunity to explore the intersection of human infrastructure and natural ecosystems in the heart of Iowa.
