Summary

Owned privately, this Earth-type dam stands at 26 feet tall and stretches 820 feet in length, with a storage capacity of 140 acre-feet. While it primarily caters to water supply purposes, the dam has a buttress core design and is situated on the TR-Duncan Creek.

Despite being in a high-risk category, with a hazard potential not available and a condition assessment yet to be rated, McGuire Dam plays a crucial role in mitigating water scarcity in the area. Its remote location and lack of associated structures make it a key asset for water resource management in the region. With state permitting and inspection in place, the dam ensures the efficient regulation and maintenance of water resources for the community.

Although the dam lacks certain regulatory oversight and enforcement, its importance in providing water supply underscores its significance in the region. With its strategic location and design, McGuire Dam stands as a critical infrastructure for ensuring water security and climate resilience in Comanche, Texas. As a key component of the water supply system, the dam highlights the role of private entities in managing and maintaining essential water resources for the community.

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.
