Summary

Built in 1909, this Earth dam stands at 34 feet high and spans 685 feet in length, with a storage capacity of 126 acre-feet for water supply purposes. Managed by the Pennsylvania Department of Environmental Protection, this dam serves as a key component in the state's water regulation and enforcement efforts.

Despite its age, Park Place No 3 is deemed to be in fair condition with a high hazard potential, prompting regular inspections to ensure its structural integrity. With a drainage area of 0.3 square miles and a normal storage capacity of 110 acre-feet, this dam plays a crucial role in managing the water resources in Schuylkill County. It is a cornerstone of water supply infrastructure in the region, supporting various local government initiatives and water management strategies.

Water resource and climate enthusiasts will appreciate the historical significance and functional importance of Park Place No 3 in sustaining the water needs of the surrounding communities. As part of the Federal ID PA00682, this dam exemplifies the collaborative efforts between state and federal agencies to safeguard water resources and ensure the resilience of water supply systems in Pennsylvania. Its presence along the Mahanoy Creek not only contributes to water storage and regulation but also serves as a reminder of the ongoing efforts to adapt to changing climate conditions and secure a sustainable water future for all.

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.
