Summary
The dam stands at a height of 18.5 feet with a storage capacity of 1130 acre-feet and a surface area of 80.8 acres. It is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure compliance with state regulations.
The dam is situated on TR-South Walnut Creek and is part of the Galveston District managed by the Mine Safety and Health Administration. With a maximum discharge of 4750 cubic feet per second, Pond Spc-66 poses a moderate risk level (3) and has an uncontrolled spillway. Despite not having a hazard potential rating or a condition assessment, the dam remains in operational condition and has not been rated for its current status.
Overall, Pond Spc-66 is a vital water resource structure in Robertson County, Texas, serving its intended purpose of storing tailings effectively. With its location near a creek and under the jurisdiction of TCEQ, the dam plays a crucial role in managing water resources and contributing to the local climate ecosystem. Ongoing monitoring and maintenance ensure the safety and functionality of Pond Spc-66 for the surrounding community and the environment.

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.
