Summary

Completed in 1988, this earth dam serves primarily for recreational purposes, offering a serene setting for water enthusiasts to enjoy. With a height of 12 feet and a length of 120 feet, Rinehart dam has a storage capacity of 62 acre-feet and covers a surface area of 6 acres within a drainage area of 1.9 square miles.

Managed by a private owner, Rinehart dam is under the regulatory jurisdiction of the Pennsylvania Department of Environmental Protection, ensuring that it meets state inspection and enforcement standards. Although designated as having a significant hazard potential, the dam's condition is reported as satisfactory, with a biennial inspection frequency. In case of emergencies, the dam's emergency action plan status and risk assessment measures remain unspecified, suggesting potential areas for further development and enhancement to ensure the safety and integrity of this water resource in West Pottsgrove Township.

Overall, Rinehart dam serves as a vital structure within the local water infrastructure, providing both recreational opportunities and water regulation for the surrounding area. As climate change continues to impact water resources, the maintenance and enhancement of structures like Rinehart dam will be crucial in ensuring the resilience and sustainability of the region's water supply and environmental health.

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.
