Overman is a private irrigation dam located in Oak Creek, Colorado, along the Yampa River. Built in 1907, this earth dam stands at a height of 10 feet and has a length of 150 feet, providing a storage capacity of 54 acre-feet. With a primary purpose of irrigation, the dam also serves fire protection, stock, and small fish pond needs in the region. Despite being categorized as low hazard potential, Overman is considered to have a high risk level due to its age and the lack of recent condition assessments.

Although the dam has not been inspected since 1990, it is regulated by the Colorado Department of Water Resources (DWR), ensuring that state permitting, inspection, and enforcement protocols are in place. While the dam's condition is currently listed as "Not Rated," its risk assessment is marked as high, indicating the need for increased monitoring and potential risk management measures. Given its critical location and importance for water resource management in the area, stakeholders and authorities may need to consider updating emergency action plans and conducting more frequent inspections to ensure the safety and integrity of the structure.
