Summary
Built in 1995, this earth dam stands at a height of 37 feet and serves primarily for tailings storage. With a storage capacity of 7379 acre-feet and a drainage area of 8.2 square miles, this dam on Peach Creek plays a crucial role in managing water resources in the region.
The dam features a spillway width of 503 feet and is equipped with outlet gates for controlled and uncontrolled discharge. Despite its age, the dam has not been rated for its condition and is not considered to have a significant hazard potential. The last inspection in 2016 highlighted the need for regular assessments to ensure the safety and integrity of the structure. With its strategic location and importance for flood control and water storage, Tmpa Gibbons Creek Mine Dam Sp 50 underscores the significance of proper dam management practices in mitigating risks and protecting communities and ecosystems.
As water resource and climate enthusiasts continue to monitor and advocate for sustainable water management practices, understanding the key features and regulatory aspects of dams like Tmpa Gibbons Creek Mine Dam Sp 50 is essential. By staying informed about the design, purpose, and condition of such infrastructure, stakeholders can contribute to the preservation of water resources, resilience to climate challenges, and the overall safety of communities downstream. With ongoing inspections and potential risk assessments, the dam's role in maintaining water security for Grimes County and beyond remains a focal point for proactive stewardship and environmental stewardship.

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.
