Summary
This privately-owned Earth dam with a height of 21 feet and length of 480 feet holds a maximum storage capacity of 156 acre-feet. Located on TR-Hillara Creek under the jurisdiction of the Fort Worth District, the dam does not have a spillway and is classified as having a high risk potential. Despite being non-federally regulated, the dam undergoes state inspection and permitting.
Water resource and climate enthusiasts will find Valmac Lake Dam intriguing for its unique design and purpose. The Buttress core of the Earth dam adds to its structural integrity, while the absence of a spillway raises questions about its flood control capabilities. The dam's location on a tributary of Hillara Creek highlights its importance for local water management and ecological conservation efforts. The dam's high risk classification suggests a need for proactive risk management measures and potential improvements to enhance its safety and efficiency.
Valmac Lake Dam presents an opportunity for further research and analysis in the context of water resource management and climate change adaptation. The dam's historical significance and ongoing role in providing essential services to the local community underscore the importance of monitoring its condition and implementing emergency preparedness measures. By studying the dam's construction, operation, and potential modifications, enthusiasts can gain valuable insights into sustainable water resource management practices and the resilience of critical infrastructure in the face of changing environmental conditions.

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.
