Summary

Managed by the USDA NRCS, this earth dam was completed in 1976 for flood risk reduction purposes. With a height of 47 feet and a length of 860 feet, the dam has a storage capacity of 5,599 acre-feet and serves a drainage area of 9.6 square miles.

Despite a fair condition assessment and a high hazard potential, Core Creek remains regulated by the Pennsylvania Department of Environmental Protection. The dam is also used for recreation and water supply purposes, with a surface area of 150 acres and a normal storage capacity of 1,476 acre-feet. In 2007, mechanical modifications were made to the dam, highlighting ongoing efforts to ensure its safety and functionality.

Located in Middletown Township, Core Creek is a significant water resource in the region, providing both flood protection and recreational opportunities for the community. With regular state inspections and enforcement in place, the dam continues to play a crucial role in managing water resources and mitigating flood risks in the area.

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.
