Summary
The dam, with a height of 11 feet and a length of 60 feet, was constructed for recreation purposes on Parks Creek. Managed by the Pennsylvania Department of Environmental Protection, Wanzo is regulated, inspected, and enforced by the state agency to ensure its safety and compliance with regulations.
The dam has a storage capacity of 251 acre-feet and a normal storage of 61 acre-feet, serving a drainage area of 0.53 square miles. Despite its low hazard potential, the condition of Wanzo has not been rated, with its last inspection conducted in June 2015. While the dam meets guidelines for emergency action plans and risk management measures, specific details such as inundation maps and risk assessments are yet to be prepared or updated.
For water resource and climate enthusiasts, Wanzo presents an intriguing case study of a small-scale earth dam designed for recreational purposes in a rural setting. The data provided offers a glimpse into the regulatory oversight, storage capacity, and hazard potential of the dam, highlighting the importance of periodic inspections and emergency preparedness. As a significant feature on Parks Creek, Wanzo serves both practical and leisure purposes, underscoring the intersection of water management and public recreation in the Pennsylvania countryside.

Dam Data Reference
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.
