Summary
The dam stands at a height of 12 feet and has a length of 2550 feet, with a storage capacity of 150 acre-feet. Despite being regulated by the Mine Safety and Health Administration, the dam does not have a spillway and poses a high risk potential.
This structure, situated in Atascosa County, Texas, does not fall under state jurisdiction for regulation, inspection, or enforcement. With a hazard potential rating of "Not Available" and a risk assessment of "High (2)", it is crucial to monitor and assess the condition of Sediment Pond 6 regularly to ensure the safety of nearby communities and the environment. The absence of an Emergency Action Plan and updated contact information raises concerns about emergency preparedness in case of a dam failure.
Water resource and climate enthusiasts in the area should take note of Sediment Pond 6 as it plays a significant role in managing sediment and water flow. With its unique design and high risk potential, this dam serves as a reminder of the importance of proper maintenance and monitoring of critical infrastructure to prevent potential disasters and protect the surrounding ecosystem.

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.
