Summary

This Grade Stabilization structure, primarily intended for grade stabilization purposes, stands as an Earth-type dam with a height of 20 feet and a length of 510 feet. With a storage capacity of 48 acre-feet and a surface area of 2.9 acres, Ski Roundtop plays a crucial role in managing water resources in the region.

Managed by the Pennsylvania Department of Environmental Protection, Ski Roundtop is subject to state regulation, inspection, and enforcement, ensuring its structural integrity and operational efficiency. With a significant hazard potential and a moderate risk assessment rating, this dam is monitored closely with biennial inspections to mitigate any potential risks and ensure public safety. The dam's uncontrolled spillway and buttress core type contribute to its functionality in managing water levels and preventing downstream flooding.

As a key infrastructure in the area, Ski Roundtop serves as a vital component in the overall water resource management system, providing grade stabilization and water storage capabilities. With its strategic location and state-regulated status, this dam plays a crucial role in safeguarding the surrounding community from potential water-related hazards while also offering recreational opportunities for visitors to enjoy the natural beauty of the Beaver Creek area.

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.
