Summary
Built with an earth core and buttress foundation, this dam has a height of 13 feet and a storage capacity of 88 acre-feet. Although it does not have a spillway, the dam is equipped with one outlet gate for water management. The structure is not regulated by the state but is subject to inspections by the Mine Safety and Health Administration.
Despite being classified as "Not Rated" in terms of condition assessment, Sedimentation Pond No 6 poses a high risk (rated 2) due to its lack of available hazard potential information. The last inspection conducted on the dam was in February 2011, indicating a potential need for further assessment and monitoring. With a surface area of 5 acres and a drainage area of 0.4 square miles, the pond serves as an essential component in controlling sediment flow and maintaining water quality in the area.
This sedimentation pond plays a crucial role in managing tailings and sediment in the region, providing valuable storage capacity and water management capabilities for the surrounding area. With its location along TR-Lambs Creek and under the jurisdiction of the Fort Worth District, the dam serves as a vital piece of infrastructure for water resource and climate enthusiasts, highlighting the importance of proper maintenance and monitoring to ensure its continued effectiveness and safety.

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.
