Summary

Managed by the local government, this man-made lake was completed in 1953 and serves primarily as a recreational hotspot for residents and visitors alike. With a surface area of 14 acres and a normal storage capacity of 32 acre-feet, Lake Caroline offers ample opportunities for fishing, boating, and other water-based activities.

The dam at Lake Caroline, classified as an Earth type with a height of 11.5 feet, plays a crucial role in regulating the water levels and ensuring the safety of the surrounding area. Despite its fair condition assessment and low hazard potential, the Pennsylvania Department of Environmental Protection closely monitors the dam's integrity through regular inspections every 5 years. The dam's primary purpose is for recreation, providing a serene setting for outdoor enthusiasts to enjoy nature and unwind in a tranquil environment.

With Queen Anne Creek feeding into the reservoir and a drainage area of 2.2 square miles, Lake Caroline represents a vital water resource in the region. Its association with the Baltimore District of the US Army Corps of Engineers underscores the importance of maintaining this picturesque lake for both recreational and environmental purposes. As climate and water resource enthusiasts, Lake Caroline offers a perfect blend of leisure and conservation, making it a must-visit destination for those who appreciate the beauty and significance of our natural landscapes.

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.
