Summary

This private-owned Earth dam, with a height of 13 feet and a length of 450 feet, serves to store a maximum of 115 acre-feet of water. Situated on the TR-Wichita River, the dam plays a crucial role in water resource management in the region.

Despite its importance, the dam's hazard potential is not available, and its condition assessment remains unrated. However, the risk assessment categorizes it as High (2), highlighting the need for ongoing monitoring and maintenance. With no spillway and limited associated structures, the dam's structural integrity and emergency preparedness are critical considerations for water resource and climate enthusiasts.

As Maddox Lake Dam continues to provide essential water supply functions, its risk management measures and potential impact on the surrounding area warrant attention. With a risk level of High (2) and no available hazard potential assessment, proactive measures are essential to ensure the dam's reliability and safety in the face of changing climate conditions and water resource demands.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
