Summary

Constructed in 1962 by the USDA NRCS, this earth dam stands at a height of 25 feet and stretches 1,180 feet in length. With a storage capacity of 369 acre-feet and a normal storage level of 15 feet, this structure plays a crucial role in mitigating flood risks in the area.

Managed by the Pennsylvania Department of Environmental Protection, Koenigs Creek is regulated, permitted, inspected, and enforced by the state to ensure its structural integrity and safety. The dam is classified as having a high hazard potential, yet its condition is assessed as satisfactory. The last inspection in December 2020 confirmed its operational effectiveness, highlighting its importance in safeguarding the surrounding community from potential flood events.

With its close association with the Natural Resources Conservation Service and its strategic location within the Philadelphia District, Koenigs Creek serves as a key component in water resource management efforts in Schuylkill County, Pennsylvania. As climate change continues to impact the frequency and intensity of extreme weather events, structures like Koenigs Creek are essential in safeguarding communities and protecting valuable resources from the threats of flooding.

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.
