Summary

The dam, completed in 1968, is an earth structure standing at a height of 13 feet and stretching 460 feet in length. With a storage capacity of 114 acre-feet, the lake offers a surface area of 24 acres for water enthusiasts to enjoy various recreational activities.

Managed by the Pennsylvania Department of Environmental Protection, Deer Lake is regulated and inspected by state authorities to ensure its safety and compliance with regulations. Despite being classified as having a high hazard potential, the dam is currently in fair condition, with the last inspection conducted in October 2020. The reservoir's normal storage capacity is 67 acre-feet, serving as a vital water resource for the surrounding area.

Situated in Wayne County, Deer Lake is a picturesque destination for water resource and climate enthusiasts to appreciate the beauty of nature while engaging in recreational pursuits. As a well-maintained reservoir with a focus on recreation, it offers a serene setting for visitors to relax and unwind, all while contributing to the local ecosystem and water management efforts in Pennsylvania.

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.
