Summary

The dam, constructed in 1948, stands at a height of 19 feet and spans 350 feet, creating a reservoir with a storage capacity of 124 acre-feet. With a surface area of 9 acres and a drainage area of 5.5 square miles, the lake provides a tranquil escape for water resource and climate enthusiasts to enjoy outdoor activities in a peaceful setting.

Managed by the Pennsylvania Department of Environmental Protection, Camp Sinoquipe Lake is classified as a low hazard potential structure with a condition assessment of 'Not Rated'. Despite not having an Emergency Action Plan (EAP) in place, the dam undergoes regular inspections every 5 years to ensure its safety and integrity. With its picturesque surroundings and recreational opportunities, the lake is a popular destination for camping, fishing, and boating, offering visitors a chance to appreciate the importance of sustainable water resource management in a changing climate.

As part of the Baltimore District, Camp Sinoquipe Lake serves as a testament to the harmonious coexistence of human recreation and environmental conservation. With its earth dam design and buttress core type, the structure exemplifies a balance between human enjoyment and ecosystem preservation. Whether admiring the beauty of the lake or engaging in water-based activities, visitors to Camp Sinoquipe can witness firsthand the importance of responsible water resource management in the face of climate variability and change.

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.
