Summary

Managed by the local government, this Earth dam, completed in 1909, stands at a height of 17.5 feet and boasts a storage capacity of 6627 acre-feet. With a surface area of 250 acres and a drainage area of 16.9 square miles, this tranquil lake offers a serene escape for water resource and climate enthusiasts alike.

Despite its scenic beauty, Edinboro Lake poses a high hazard potential and is currently assessed as being in poor condition. Regular inspections are conducted to ensure the dam's structural integrity and safety, with the most recent inspection taking place in October 2020. The Pennsylvania Department of Environmental Protection oversees the state's regulatory requirements, permitting, inspections, and enforcement to maintain the dam's functionality and safety standards.

Water enthusiasts can enjoy various recreational activities at Edinboro Lake, such as fishing, boating, and picnicking, while also appreciating the critical role this water resource plays in the local ecosystem. As climate change continues to impact water resources, it is essential to prioritize the maintenance and upkeep of dams like Edinboro Lake to ensure their long-term sustainability and resilience in the face of environmental challenges.

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.
