Summary
The dam, primarily made of earth with a buttress core type, helps regulate the flow of Panther Hollow Run, a nearby river/stream, to mitigate potential flooding in the area. The state of Pennsylvania oversees the regulation, permitting, inspection, and enforcement of the dam to ensure its safe operation and compliance with environmental standards.
Despite its critical role in flood risk reduction, Panther Hollow Lake poses a high hazard potential due to its condition being labeled as "Not Rated." Regular inspections are conducted, with the most recent one taking place in February 2021. Emergency action plans and risk assessment measures are yet to be fully developed, highlighting the need for proactive management and maintenance of this essential water infrastructure. As a significant water resource in the region, Panther Hollow Lake serves as a focal point for water resource and climate enthusiasts interested in understanding the intersection of infrastructure, environmental protection, and community safety.
With its strategic location and importance in managing water resources, Panther Hollow Lake offers a fascinating case study for those passionate about water infrastructure and climate resilience. As discussions around sustainable water management and climate adaptation continue to gain prominence, the management and maintenance of Panther Hollow Lake serve as a prime example of the complexities involved in balancing flood risk reduction with recreational benefits. By delving into the specifics of its design, regulation, and hazard potential, enthusiasts can gain valuable insights into the challenges and opportunities associated with safeguarding water resources in an era of changing climate patterns.

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.
