Completed in 1994, this earth dam stands at a height of 25 feet and has a length of 545 feet. Its primary purpose is designated for fire protection, stock, or a small fish pond, with a normal storage capacity of 43 acre-feet and a maximum storage of 95 acre-feet.
Managed by the Iowa Department of Natural Resources, Oaknoll Dam is situated along the TR-Iowa River, with a drainage area of 0.12 square miles. Despite its satisfactory condition assessment as of July 2020, the dam poses a high hazard potential and is subject to biennial inspections to ensure its structural integrity and safety. While an uncontrolled spillway is present with a width of 2 feet, there are no outlet gates or associated structures linked to the dam.
Although Oaknoll Dam presents a moderate risk level, its strategic location and purpose make it a vital resource for fire protection and recreational activities in the region. With ongoing monitoring and maintenance efforts, the dam continues to serve its intended functions while remaining a focal point for water resource and climate enthusiasts interested in the management of dams and reservoirs.
