Green Acres Dam, located in Lee County, Iowa, was completed in 1971 and is owned by a private entity. Designed by the USDA NRCS, this earth dam stands at 26 feet in height and spans 325 feet in length, with a primary purpose of providing fire protection and serving as a stock or small fish pond. The dam has a storage capacity of 44 acre-feet and covers a surface area of 2.5 acres, with a drainage area of 0.22 square miles along TR-Sugar Creek.

Despite being classified as having a low hazard potential, the dam's condition has not been rated, and it lacks certain emergency preparedness measures such as an Emergency Action Plan (EAP). However, it is regulated and inspected by the Iowa DNR, with state permitting and enforcement in place. The risk assessment for Green Acres Dam is considered moderate, with a risk level of 3 out of 5, indicating a need for ongoing monitoring and potential risk management measures to ensure the safety and stability of the structure for the surrounding community and environment.
