Summary
Standing at a height of 24 feet with a length of 705 feet, the dam has a storage capacity of 129 acre-feet and a surface area of 6 acres. It is situated on the West Fork Trinity River, within the Fort Worth District of the US Army Corps of Engineers. Despite being privately owned, the dam is subject to state permitting and inspection requirements.
With a hazard potential of "Not Available" and a risk assessment rating of "High (2)", Worthington Lake No 1 Dam faces potential risks that necessitate close monitoring and management. While the dam does not have a spillway, it is equipped with one outlet gate. The condition of the dam is currently not rated, and there is no available information on emergency action plans, inundation maps, or risk management measures. The dam is not under the jurisdiction of state regulatory agencies, highlighting the importance of proactive risk assessment and mitigation by the private owner.
As an earth dam designed with a buttress core, Worthington Lake No 1 Dam stands as a vital structure for local water resource management and fire protection in the region. With its close proximity to the West Fork Trinity River, the dam plays a crucial role in maintaining water supply and supporting small-scale aquatic life. However, its high risk potential underscores the need for regular inspection, maintenance, and emergency preparedness to ensure the safety and integrity of the dam and surrounding areas.

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.
