Summary
Managed by the Oklahoma Water Resources Board, this earth dam structure stands at 40 feet tall and spans 364 feet in length. With a storage capacity of 55.02 acre-feet and a surface area of 2.92 acres, Maddux serves as a crucial habitat for local wildlife in the area.
Despite its low hazard potential, Maddux has a very high risk assessment rating due to its structural condition not being rated. The dam features a controlled spillway and a single valve outlet gate. The last inspection of Maddux was conducted in April 2010, with a recommended inspection frequency of 5 years. While emergency preparedness measures are not fully assessed, the risk management of this dam remains a top priority for ensuring the safety and security of the surrounding community.
Climate and water resource enthusiasts can appreciate the importance of maintaining and monitoring the condition of structures like Maddux. With its critical role in ecological conservation and water storage, Maddux presents an opportunity for sustainable management practices and collaboration between private owners and state agencies to ensure the longevity and safety of this valuable resource for the future.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
