Summary
With a height of 27 feet and a length of 400 feet, the dam provides a storage capacity of 61 acre-feet and covers a surface area of 7 acres. Despite its historical significance and recreational purpose, the dam's condition is rated as poor, with a high hazard potential.
The Pennsylvania Department of Environmental Protection oversees the regulation, permitting, inspection, and enforcement of the dam, ensuring compliance with state guidelines and safety standards. The last inspection in March 2021 revealed the need for improvement, highlighting the urgency of addressing the dam's deteriorating condition. With a high hazard potential, the community of Cokeburg must prioritize maintenance and risk management measures to ensure the safety of downstream residents and infrastructure.
As water resource and climate enthusiasts, the data on Cokeburg's dam serves as a reminder of the importance of infrastructure resilience and proactive maintenance in the face of changing environmental conditions. The presence of a high hazard potential underscores the need for regular monitoring, emergency preparedness, and community engagement to mitigate risks associated with dam failure. By leveraging state resources and expertise, Cokeburg can work towards improving the dam's condition, enhancing public safety, and safeguarding its recreational and environmental assets for future generations.

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.
