Summary
Built in 1965, this earth dam rises 12 feet high and spans 500 feet in length, creating a serene lake with a maximum storage capacity of 130 acre-feet. The primary purpose of this dam is to provide recreational opportunities for water and climate enthusiasts in the area, offering a peaceful escape for fishing, boating, and enjoying the natural beauty of the surroundings.
Managed by a private owner, Hallmark Lake Dam is not regulated by the state but undergoes regular inspections to ensure its safety and structural integrity. Despite not having a spillway, the dam is designed to manage high-risk situations with a hazard potential rated as "Not Available" and a risk assessment categorizing it as high. While the condition assessment is not rated, the dam continues to serve as a popular destination for outdoor enthusiasts seeking a tranquil retreat in the heart of Texas.
With its strategic location on TR-Caddo Creek and its proximity to Fort Worth District, Hallmark Lake Dam remains a key feature in the local landscape, offering a haven for wildlife and a recreational oasis for visitors. The dam's rich history, coupled with its commitment to safety and environmental stewardship, make it a noteworthy site for those interested in water resources and climate management. As it continues to stand the test of time, Hallmark Lake Dam serves as a reminder of the enduring legacy of water infrastructure in shaping our understanding of the natural world.

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.
