Summary
This earth dam, primarily designed for water supply purposes, holds a storage capacity of 952 acre-feet. Situated on TR-Elm Creek, the dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes state inspections and enforcement. Despite being rated as not available for hazard potential and not yet assessed for condition, the dam presents a high risk level (2) according to the data.
With its primary purpose being water supply, Mangum Lake No 2 Dam serves as a vital structure in the region, ensuring adequate water resources for the surrounding area. Although lacking certain risk management measures and emergency preparedness protocols, the dam remains in operation and is integral to the local water infrastructure. The risk assessment categorizes the dam as high risk (2), indicating the need for further evaluation and potential mitigation strategies to enhance its safety and resilience in the face of climate variability and extreme weather events.
As climate change continues to impact water resources and infrastructure, the significance of structures like Mangum Lake No 2 Dam becomes more pronounced. Ensuring the safety and functionality of such dams is crucial for water security and resilience in the face of changing environmental conditions. With ongoing inspections and regulatory oversight by the TCEQ, efforts to monitor and address any potential risks associated with the dam are essential to safeguarding water resources and communities in the region.

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.
