Summary

Completed in 1938, this earth dam serves multiple purposes, including water supply and other critical functions. It stands on Big Elm Creek and is regulated by the Texas Commission on Environmental Quality (TCEQ), with regular inspections and enforcement measures in place to ensure its safety and compliance.

With a maximum storage capacity of 136,076 acre-feet and a normal storage capacity of 70,300 acre-feet, Fort Phantom Hill Dam plays a crucial role in managing water resources in the region. Its spillway, with a width of 7856 feet, is uncontrolled, and the dam features outlet gates for operational control. Despite its age, the dam is rated as having moderate risk potential, highlighting the importance of ongoing risk management and maintenance efforts to safeguard this vital infrastructure for the community.

As part of the Fort Worth District, Fort Phantom Hill Dam not only provides essential water storage but also contributes to flood control and recreational opportunities. Its historical significance, combined with its functional importance, makes it a noteworthy site for water resource and climate enthusiasts interested in the intersection of infrastructure, sustainability, and environmental stewardship in Texas.

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.
