Summary
Built in 1908, this dam stands at a height of 29 feet and has a length of 455 feet, with a storage capacity of 159 acre-feet. Situated on TR Crooked Creek, it is regulated by the Pennsylvania Department of Environmental Protection and is subject to state permitting, inspection, and enforcement.
Despite being classified as having a high hazard potential, Cummings is currently assessed to be in fair condition. The dam's emergency action plan status and risk assessment details are currently unavailable, raising questions about its readiness in the face of potential emergencies. With a drainage area of 1.7 square miles and a surface area of 8 acres, Cummings offers recreational opportunities in Rayne Township but may require closer monitoring and risk management measures to ensure the safety of nearby communities and the environment.
As a structure under local government ownership, Cummings represents a blend of historical significance and contemporary challenges in water resource management. With its location in a picturesque setting but with potential risks associated with its hazard potential, the dam serves as a reminder of the importance of proper maintenance, monitoring, and emergency preparedness in safeguarding water resources and communities against the impacts of climate change and natural disasters.

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.
