Summary
This Earth-type dam stands at a height of 13 feet and has a length of 860 feet, providing a storage capacity of 208 acre-feet. With a primary purpose of water supply, this dam serves the community by storing up to 114 acre-feet of water for various uses.
Managed by the Mine Safety and Health Administration, Sediment Pond 19b has a high risk assessment rating of 2, indicating the potential for hazards. Despite its high risk, the dam's condition is currently not rated, highlighting the need for further assessment and potentially management measures to ensure its safety and longevity. With one outlet gate and no spillway, the dam's structure and hydraulic height of 13 feet contribute to its intended function of water supply.
While the sediment pond has not been inspected recently, its presence and operation are crucial for the surrounding area's water needs. With its location in Atascosa County, Texas, Sediment Pond 19b plays a vital role in water resource management and climate resilience efforts in the region. As climate change continues to impact water availability, structures like Sediment Pond 19b become increasingly important for maintaining a stable water supply for the community.

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.
