Summary

Built in 1928, this concrete dam stands at a height of 36 feet and has a length of 800 feet, with a storage capacity of 1713 acre-feet. The dam's primary purpose is water supply, and it is regulated by the Pennsylvania Department of Environmental Protection.

Despite being classified as having a high hazard potential, Pickering Creek Dam is currently in fair condition, as per the last inspection in November 2020. The dam's emergency action plan status and risk assessment details are not specified in the data. With a drainage area of 38.4 square miles and a normal storage capacity of 1143 acre-feet, the dam plays a significant role in managing water resources in the area.

Ensuring the safety and maintenance of Pickering Creek Dam is crucial for water resource and climate enthusiasts, as it not only provides water supply but also helps regulate the flow of Pickering Creek. With its historical significance and environmental impact, the dam serves as a vital infrastructure in the region, highlighting the importance of proper management and upkeep to mitigate potential risks and ensure long-term sustainability.

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.
