Summary
The dam stands at 34 feet in height and spans 412 feet in length, creating a reservoir with a maximum storage capacity of 80 acre-feet. Despite its small size, the dam plays a crucial role in providing water supply and recreational opportunities for the surrounding area.
Located on the TR-Gibson Creek and managed by the Fort Worth District of the US Army Corps of Engineers, Thurber Lake No 4 Dam is a key feature in the local water resource infrastructure. However, the dam is not regulated by the state and has not been rated for its condition assessment. With a high risk assessment of 2, there is a need for increased monitoring and potentially, improvements to ensure the safety and stability of the dam for the future.
Water resource and climate enthusiasts will be intrigued by the unique design and purpose of Thurber Lake No 4 Dam, as well as the challenges it faces in terms of risk management and safety. With its scenic location and important role in providing water supply and recreational opportunities, the dam serves as a reminder of the delicate balance between human infrastructure and environmental preservation in the face of changing climate patterns.

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.
