Summary

This picturesque lake, formed by an earth dam in 1959 on Beaver Creek, serves primarily for recreational purposes, boasting a surface area of 342 acres and a maximum storage capacity of 8,000 acre-feet. With a normal storage capacity of 2,800 acre-feet, the lake provides a serene setting for water and climate enthusiasts to enjoy various outdoor activities such as fishing, boating, and wildlife watching.

The dam at Pinchot Lake stands 50 feet tall and spans a length of 626 feet, enhancing the beauty of the surrounding landscape while also providing flood control measures for the area. Despite being classified with a high hazard potential, the dam is reportedly in fair condition as of the last inspection in March 2021. While there are no associated structures or locks at the site, the dam continues to be regularly inspected to ensure the safety and integrity of the structure for both recreational and flood control purposes.

Water and climate enthusiasts visiting Pinchot Lake can appreciate the efforts of the Pennsylvania Department of Environmental Protection in managing this vital resource. The lake offers a peaceful retreat for outdoor enthusiasts seeking to connect with nature and enjoy the benefits of a well-maintained water resource in the heart of Pennsylvania. With its rich history, diverse wildlife, and recreational opportunities, Pinchot Lake remains a beloved destination for those passionate about water conservation and climate resilience.

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.
