Miller Dam, located in Fremont, Iowa, along the TR-NISHNABOTNA RIVER, was completed in 1961 with a primary purpose of fire protection, stock, or small fish pond. This earth dam stands 45 feet tall and spans 491 feet, with a storage capacity of 235 acre-feet. The dam is owned privately and regulated by the Iowa Department of Natural Resources, with state permitting, inspection, and enforcement in place.

Despite its low hazard potential, Miller Dam poses a moderate risk, with a risk assessment rating of 3. The dam has not been rated for its condition assessment, and the last inspection was conducted in 1990. While the dam has not undergone modification in recent years, it is important for water resource and climate enthusiasts to be aware of its presence and potential impact on the surrounding area.

In the event of an emergency, the dam does not have an Emergency Action Plan (EAP) prepared or updated, raising concerns about its readiness to respond to unforeseen events. With a surface area of 14 acres and a drainage area of 0.26 square miles, Miller Dam serves as a vital resource for fire protection and stock, highlighting the importance of ongoing monitoring and maintenance to ensure its safety and effectiveness in the face of changing environmental conditions.
