Summary

Built in 1925, this earth dam stands at a height of 15 feet and has a length of 320 feet, with a primary purpose of water supply. It holds a normal storage capacity of 61 acre-feet and serves the TR North Branch Black Lick Creek, benefiting the surrounding area with essential water resources.

Managed by the Pennsylvania Department of Environmental Protection, Shirfs Run is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. With a significant hazard potential, this dam is subject to regular inspections every two years to monitor its condition. Despite being not rated in terms of condition assessment, the dam continues to play a crucial role in water supply management for the region.

For water resource and climate enthusiasts, Shirfs Run offers a fascinating case study in dam infrastructure and water management. With its rich history dating back almost a century, this structure exemplifies the importance of maintaining and regulating water resources to ensure sustainability and safety for local communities. Its association with the TR North Branch Black Lick Creek highlights the interconnectedness of water systems and the critical role dams play in providing essential resources for both human and environmental needs.

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.
