Summary
Managed by the Pennsylvania Department of Environmental Protection, this local government-owned lake spans 118 acres and has a maximum storage capacity of 782 acre-feet, making it an important water resource in the region. The dam, with a height of 11 feet and a length of 130 feet, serves primarily for recreation purposes, attracting water resource and climate enthusiasts alike.
Despite its significant hazard potential, Clear Lake has not been rated for its condition assessment. The dam, constructed using buttress core types with unknown foundations, is subject to regular state inspections, with the last inspection conducted in October 2020. The lake's drainage area of 14.1 square miles feeds into the East Branch Oil Creek, highlighting its vital role in the local ecosystem. With its serene surroundings and historical significance, Clear Lake remains a popular destination for outdoor enthusiasts seeking to explore the intersection of water resources and climate in Pennsylvania.

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.
