Summary
This earth dam, primarily serving the purpose of water supply, holds a storage capacity of 670 acre-feet, with a normal storage of 370 acre-feet. The dam is owned privately and regulated by the Texas Commission on Environmental Quality (TCEQ), with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
With a hazard potential rating of "Not Available" and a risk assessment categorized as High (2), Coggin Lake Dam poses a significant concern in terms of potential risks and safety measures. Despite lacking specific information on its condition assessment, emergency action plan, and risk management measures, it is clear that further evaluation and monitoring are essential to mitigate any potential threats associated with the dam. The dam does not have a spillway and is equipped with one outlet gate, raising questions about its ability to handle excess water flow in case of heavy rainfall or other emergencies.
As an enthusiast of water resources and climate, Coggin Lake Dam presents an intriguing case study that highlights the importance of dam safety and risk management in the face of evolving environmental challenges. Its location on TR-Clear Creek, in the Fort Worth District, calls for a comprehensive approach to monitoring and addressing potential hazards to ensure the continued protection of communities and ecosystems downstream.

Dam Data Reference
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.
