Central City Milldam, located in Linn County, Iowa, is a gravity dam built in 1965 along the Wapsipinicon River for recreational purposes. The dam stands at a height of 14 feet and spans a length of 490 feet, with a storage capacity of 170 acre-feet and a surface area of 25 acres. Despite its low hazard potential, the dam's risk assessment indicates a moderate level of risk, emphasizing the need for ongoing monitoring and management measures.

Managed by the local government and regulated by the Iowa Department of Natural Resources, Central City Milldam serves as a popular spot for outdoor activities such as fishing, boating, and wildlife observation. While the dam has not been rated for its condition, the last inspection conducted in 1989 revealed no immediate concerns. The dam's uncontrolled spillway type and soil foundation suggest a reliance on natural drainage processes for flood control, highlighting the importance of regular inspections and maintenance to ensure its continued safety and functionality.

As climate change continues to impact water resources and weather patterns, Central City Milldam serves as a vital infrastructure for both recreation and flood management in the region. With its historical significance and scenic location along the Wapsipinicon River, the dam remains a focal point for water resource and climate enthusiasts seeking to understand the interconnectedness of human activities and natural systems in a changing environment.
