Monday Dam, located in Ringgold County, Iowa, is a private dam with a primary purpose of fire protection, stock, or small fish pond. Built in 2002 by the NRCS, this earth dam stands at a height of 26 feet and spans 509 feet in length. With a storage capacity of 137 acre-feet and a surface area of 8.9 acres, Monday Dam regulates the flow of the Middle Fork Grand River.

Despite its low hazard potential and moderate risk assessment, Monday Dam is not currently rated for its condition. The dam is state regulated by the Iowa Department of Natural Resources, with inspection, permitting, and enforcement requirements in place. The spillway type is uncontrolled, with a width of 2 feet, and there are no outlet gates or associated structures.

Water resource and climate enthusiasts will appreciate Monday Dam for its role in fire protection and wildlife habitat. The dam's location in a rural area of Iowa provides valuable storage for agricultural and ecological purposes. While the dam has a relatively low hazard potential, ongoing risk management measures and inspection protocols ensure the safety and functionality of this important water resource infrastructure.
