Summary

The dam stands at a height of 51 feet and spans a length of 3500 feet, providing a storage capacity of 822 acre-feet. The primary purpose of the dam is to manage tailings and protect the surrounding area from potential inundation.

Managed by the Maryland Dam Safety regulatory agency, York Bldg Products Settling Pond 11 has been assessed to be in fair condition with a significant hazard potential. The dam is equipped with a needle outlet gate system and has a drainage area of 0.01 square miles. Despite its fair condition, the dam is subject to regular inspections, with the last one conducted in July 2020, and an emergency action plan is in place to address any potential risks.

With its high risk assessment ranking, York Bldg Products Settling Pond 11 serves as a critical infrastructure for flood control in the region. As water resource and climate enthusiasts, staying informed about the condition and management of this dam is essential to ensuring the safety and well-being of the local community and environment.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
