Summary
Constructed in 1973 by USDA NRCS, this earth dam stands at a height of 52 feet and stretches to a length of 1200 feet, providing crucial protection to the surrounding area. With a storage capacity of 3920 acre-feet and a drainage area of 7.3 square miles, Greenlick Run plays a significant role in managing water flow and reducing the risk of flooding in the region.
Managed by the Pennsylvania Department of Environmental Protection, this dam is under state regulation, inspection, and enforcement, ensuring its structural integrity and operational effectiveness. The primary purpose of Greenlick Run is flood risk reduction, although it also serves recreational purposes for the community. Despite its high hazard potential, the condition of the dam is assessed as satisfactory, and regular inspections are conducted to maintain its safety standards. With its strategic location and design, Greenlick Run exemplifies the importance of water resource management and climate resilience efforts in safeguarding communities against natural disasters.
Supported by the Natural Resources Conservation Service and designed to buttress core types, Greenlick Run exemplifies a collaborative effort between local government agencies and federal entities to protect the environment and ensure public safety. With its significant storage capacity and efficient drainage system, this dam continues to play a crucial role in managing water flow and mitigating flood risks in the region. As a key infrastructure asset in the area, Greenlick Run stands as a testament to the importance of sustainable water resource management and climate adaptation strategies for a more resilient future.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
