Summary
This earth dam, completed in 1967, stands at a height of 25 feet and stretches 1150 feet in length, with a storage capacity of 169 acre-feet. Situated on TR-SANDY CREEK, this dam plays a crucial role in managing water resources in the area, with a controlled spillway and one outlet gate for efficient water release.
Despite its low hazard potential, SCS-Wildhorse Creek Site-116 is classified as having a very high risk level, emphasizing the importance of monitoring and maintenance. The dam has not been inspected since 1980, with an inspection frequency of 5 years. While the condition assessment is not rated, the dam's risk management measures and emergency preparedness plans are not detailed. With the potential for high discharge rates and a significant impact on the surrounding area, continued vigilance and risk assessment are essential for the long-term safety and sustainability of this water resource infrastructure.
With its strategic location in the Fort Worth District and its vital role in flood risk reduction, SCS-Wildhorse Creek Site-116 serves as a key component in water management efforts in the region. As climate change poses new challenges to water resources, maintaining and updating infrastructure like this dam will be crucial to ensure the safety and resilience of communities downstream. Further assessments and improvements may be needed to address the high risk associated with this dam and to uphold its effectiveness in safeguarding against floods and preserving water quality for future generations.

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.
