Summary

Constructed in 1905, this Earth dam stands at a height of 34 feet and spans 350 feet in length, with a storage capacity of 500 acre-feet. The lake covers an area of 56 acres and is fed by Wright Creek, making it a vital resource for the surrounding community.

Despite its historical significance, Penn Lake is facing challenges in terms of its structural integrity. The dam has been classified as having a high hazard potential and poor condition assessment, raising concerns for its long-term sustainability. In response, the Pennsylvania Department of Environmental Protection oversees state-regulated permitting, inspection, and enforcement to ensure the safety and maintenance of the dam. With a risk assessment rating of moderate, there is a pressing need for risk management measures to address the dam's deficiencies and safeguard the surrounding area from potential hazards.

As water resource and climate enthusiasts, it is crucial to monitor the ongoing efforts to maintain and improve Penn Lake's infrastructure. With a long history of modifications and recent inspections, the lake serves as a focal point for environmental stewardship and community engagement. By staying informed and advocating for sustainable practices, we can help preserve Penn Lake for future generations to enjoy its recreational benefits while protecting the local ecosystem and water resources.

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.
