Summary

Built in 1993 by COBOURN, LINSEISEN & RATLIFF INC, this earth dam stands at a height of 11 feet and spans a length of 200 feet, with a storage capacity of 14 acre-feet. The dam's primary purpose is to mitigate flooding in the area and protect downstream communities from potential water-related hazards.

Managed by a private owner, the Heb Detention Pond Dam is regulated and inspected by the Texas Commission on Environmental Quality (TCEQ) to ensure compliance with state standards. The dam features an uncontrolled spillway with a width of 31 feet and three uncontrolled outlet gates to manage water flow during heavy rainfall events. Despite its satisfactory condition assessment, the dam has a moderate risk level, indicating the need for ongoing monitoring and risk management measures to maintain its effectiveness in flood control.

As a critical infrastructure in Montgomery County, Texas, the Heb Detention Pond Dam plays a vital role in safeguarding the surrounding area from flood risks. With its strategic location and design, this earth dam serves as a key asset in the region's water resource management and climate resilience efforts, highlighting the importance of proactive maintenance and risk mitigation strategies to ensure its continued protection of the local 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.
