Summary

This private earth dam, with a height of 30 feet and length of 595 feet, provides a storage capacity of 268 acre-feet. Situated on TR-Flat Creek, the dam is regulated by the state of Texas, with permitting and inspection requirements in place to ensure its safety and functionality.

Despite its importance, Monroe Dam has not been rated for its condition, and its hazard potential is not available. The last inspection took place in January 1991, indicating a need for more frequent monitoring to assess any potential risks. With a high risk assessment level, there is a need for effective risk management measures to be put in place to safeguard the surrounding area in case of emergencies.

As water resource and climate enthusiasts, it is essential to recognize the significance of Monroe Dam in providing essential services to the community. Understanding the structural and regulatory aspects of the dam can help in advocating for improved maintenance and risk management practices to ensure its long-term sustainability and safety for both human and environmental needs.

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.
