Summary

Built in 1971, this earth dam stands at a height of 14 feet and spans a length of 1550 feet, offering a storage capacity of 470 acre-feet. Despite its primary function, the dam has not been rated for its condition, presenting a potential risk due to high hazard levels.

Managed by a private owner, County Line Tank Dam falls under state permitting and inspection regulations, ensuring its operational safety. Situated along the TR-Camp Lake Slough, this dam is designed with a buttress core type and lacks a spillway, making its risk assessment crucial for the surrounding areas. With a risk rating of 2 (considered high), it underscores the importance of regular monitoring and maintenance to prevent any potential hazards or emergencies.

As part of the water infrastructure in Zavala County, Texas, County Line Tank Dam plays a significant role in water management and conservation efforts. With its strategic location and storage capacity, this dam serves as a vital resource for the local community, highlighting the importance of sustainable practices and proactive risk management in safeguarding water resources and adapting to changing climate conditions.

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.
