Summary

Built in 1929, this earth dam stands at a height of 9 feet and spans 75 feet in length, holding a storage capacity of 66.1 acre-feet. The dam is regulated by the Pennsylvania Department of Environmental Protection, ensuring proper inspections and enforcement to maintain its satisfactory condition.

Situated in Dyberry Township along the Spring Brook, Lake Elsie offers 22 acres of surface area for water enthusiasts to enjoy. Despite its relatively small drainage area of 0.7 square miles, the reservoir provides significant recreational opportunities for locals and visitors alike. With a hazard potential deemed as significant, the dam's emergency action plan and risk management measures play crucial roles in ensuring the safety and security of the surrounding community.

Managed under private ownership, Lake Elsie serves as a vital water resource for recreational activities in the region. Its historical significance and importance in the local landscape make it a valuable asset for water resource and climate enthusiasts interested in exploring the intersection of human infrastructure and environmental stewardship.

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.
