Mc Cormick Dam, located in Marion, Iowa near Red Rock Reservoir, was completed in 1967 by the USDA NRCS. This private dam serves multiple purposes, including fire protection and creating a small fish pond. Standing at a height of 26 feet and a length of 507 feet, the dam has a storage capacity of 110 acre-feet and covers a surface area of 7.6 acres. The dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections to ensure its safety and compliance with state regulations.

Despite being classified as having a low hazard potential, Mc Cormick Dam is considered to have a moderate risk level. While the dam itself is in good condition and has not been rated for its current state, there is a risk assessment rating of 3 out of 5. The dam does not have an Emergency Action Plan (EAP) in place, and it is unclear if it meets all safety guidelines. The dam is not owned or funded by any federal agencies, but it is under the jurisdiction of the Kansas City District of the US Army Corps of Engineers.

Enthusiasts of water resources and climate will find Mc Cormick Dam to be an intriguing case study in dam management and safety. Its unique location near the Red Rock Reservoir and its multiple purposes make it a valuable asset for the local community. With its regular inspections and moderate risk level, the dam highlights the importance of proper maintenance and monitoring for ensuring the safety of water infrastructure in the face of changing climate conditions.
