Summary

The dam, designed by HKS INC, stands at a height of 23.5 feet and has a hydraulic height and structural height of the same measurement. With a length of 510 feet and a storage capacity of 81 acre-feet, the dam overlooks the TR-MARSHALL BRANCH river or stream, offering a surface area of 7.9 acres for recreational activities.

Maintained and regulated by the Texas Commission on Environmental Quality (TCEQ), Fidelity North Lake Dam has two uncontrolled outlet gates and a spillway width of 520 feet. The dam has a moderate risk assessment level of 3 and last underwent inspection in February 2016, with a scheduled inspection frequency of every 5 years. While the hazard potential and condition assessment of the dam are currently not available or rated, the emergency action plan (EAP) was last reviewed in February 2011, indicating a commitment to safety and preparedness in case of emergencies.

Overall, Fidelity North Lake Dam serves as a crucial structure for both recreational activities and water resource management in Tarrant County, Texas. With its strategic location and design features, the dam plays a vital role in providing a safe and enjoyable environment for visitors while ensuring compliance with state regulations and maintaining a moderate level of risk management.

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.
