Summary
This private-owned earth dam stands at a height of 20 feet and spans a length of 920 feet, with a storage capacity of 224 acre-feet. Despite being designed as a buttress dam with unknown foundations, the dam currently holds a high risk assessment rating of 2, indicating the potential for hazards.
The dam lacks a spillway and is not regulated by the state, although it undergoes regular inspections and permitting. With its serene surroundings and historical significance, Mill Pond Dam serves as a popular destination for water resource and climate enthusiasts seeking outdoor recreation. As a notable feature in the Fort Worth District, this dam offers a glimpse into Texas's rich hydrological landscape and the importance of maintaining dam safety to protect both the environment and local communities.
Although the condition assessment remains unrated and hazard potential data is not available, Mill Pond Dam's risk management measures and emergency action plan status are unknown. With its high-risk designation, it is crucial for stakeholders and authorities to prioritize the safety and maintenance of this dam to prevent potential disasters and ensure the continued enjoyment of this recreational resource by visitors and residents alike.

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.
