Summary

Built in 1960, this Earth dam stands at 14 feet tall and spans 300 feet in length, providing a storage capacity of 36 acre-feet. Although the dam is categorized as having a significant hazard potential, its condition assessment is rated as fair, with the last inspection conducted in November 2012.

Managed by the Pennsylvania Department of Environmental Protection, Savery Mill is subject to state regulation, permitting, inspection, and enforcement. The dam's association with the Baltimore District of the US Army Corps of Engineers ensures compliance with federal guidelines for safety and operation. With the potential for recreational use and the importance of maintaining its structural integrity, Savery Mill serves as a focal point for water resource and climate enthusiasts interested in the management of dams and reservoirs in the region.

As a key feature in Chester County, Pennsylvania, Savery Mill not only provides essential storage and flood control functions but also offers opportunities for outdoor activities and enjoyment. With its historical significance dating back several decades, the dam continues to be a vital asset for the community. As enthusiasts in water resource and climate management monitor the dam's condition and regulatory oversight, Savery Mill remains a symbol of the delicate balance between human intervention and natural ecosystems in the region.

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.
