Summary
With a dam height of 12.1 feet and a NID storage capacity of 96 acre-feet, this concrete structure serves as a crucial water resource in the region. The dam's primary purpose remains unspecified, yet its low hazard potential and moderate risk assessment indicate a stable infrastructure that contributes to the area's overall water management strategy.
Despite lacking certain key data points such as completion year and inspection dates, Vernay Lake Dam maintains a normal storage capacity of 84 acre-feet and a surface area of 9 acres. The dam's uncontrolled spillway type suggests a simple yet effective design, while its location within the Philadelphia District underscores its significance within the broader infrastructure network. As a focal point for water enthusiasts and climate advocates, Vernay Lake Dam represents a harmonious balance between private ownership, state jurisdiction, and environmental stewardship.
With a risk assessment rating of moderate (3) and a condition assessment of "Not Rated," Vernay Lake Dam presents an intriguing case study for those interested in water resource management and climate resilience. While details such as the dam's year of completion and last inspection date remain elusive, the dam's low hazard potential and state-regulated status offer a glimpse into its overall reliability. As discussions around water infrastructure and climate adaptation continue to evolve, Vernay Lake Dam serves as a valuable example of the intersection between human-made structures and natural ecosystems.

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.
