Miller Dam, located in Page, Iowa, along the Middle Tarkio River, was completed in 1966 by the USDA NRCS. This private dam serves multiple purposes, including fire protection and creating a small fish pond, with a primary purpose of providing water for stock. With a height of 29 feet and a length of 482 feet, the dam has a storage capacity of 63 acre-feet and covers a surface area of 4.5 acres. Despite its low hazard potential and moderate risk assessment, the dam is regulated and inspected by the Iowa Department of Natural Resources to ensure its safety and compliance with state regulations.

Owned privately, Miller Dam is classified as an earth dam with a soil foundation. It does not have a controlled spillway and has not been modified in recent years. While its condition is currently not rated, the dam is regularly monitored to prevent any potential risks. In case of emergencies, the dam does not have an Emergency Action Plan (EAP) in place, and its hazard potential is considered low. However, with its crucial role in supporting local water resources and the ecosystem, ongoing risk management measures are essential to ensure the safety and longevity of Miller Dam for the community and the environment.
