Summary
This Earth-type dam, completed in 1990 by Morrison Knudsen, stands at a height of 20 feet and spans 2600 feet, providing storage of 394 acre-feet of water. The dam serves a primary purpose of "Other" and is associated with the TR-Gibbons Creek river system.
Despite not having a spillway, the dam's risk assessment categorizes it as having a high risk level, with a hazard potential that is not readily available. The condition assessment of the dam is currently not rated, and its last inspection was conducted in October 1994. The dam's emergency action plan status, inundation maps, and risk management measures are not disclosed in the data. However, with its strategic location and significant storage capacity, the Tmpa Gibbons Creek Mine Dam Sp 10 10a plays a crucial role in water management within the region.
For water resource and climate enthusiasts, Tmpa Gibbons Creek Mine Dam Sp 10 10a offers a fascinating case study in dam infrastructure and water management practices. With its historical data indicating completion in 1990 and a significant storage capacity of 394 acre-feet, the dam presents both challenges and opportunities in terms of risk management and emergency preparedness. As part of the TR-Gibbons Creek system in Texas, this Earth-type dam highlights the importance of regulatory oversight and periodic inspections to ensure its continued functionality and resilience in the face of changing environmental conditions.

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.
