Summary

With a dam height of 12.5 feet and a length of 550 feet, the earth dam has a storage capacity of 179 acre-feet, providing both normal and maximum storage for recreational purposes. The dam, classified as having a low hazard potential and fair condition assessment, is managed by the Pennsylvania Department of Environmental Protection.

This picturesque Lily Pond offers a surface area of 22 acres and is surrounded by the natural beauty of Milford Township. The uncontrolled spillway, with a width of 45 feet, adds to the charm of this recreational area. While the dam poses a moderate risk, the state enforcement, inspection, and permitting ensure the safety and regulatory compliance of the structure, making it a popular destination for water resource and climate enthusiasts who appreciate sustainable water management practices.

Overall, Lily Pond serves as not only a recreational oasis but also as a testament to the importance of effective dam management and regulation in protecting water resources.

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.
