Summary

Built in 1891, this dam stands at a height of 27 feet and has a length of 243 feet, providing a storage capacity of 6,910 acre-feet for water supply purposes. Situated on Huntsville Creek in Lehman Township, this structure is regulated and inspected by the Pennsylvania Department of Environmental Protection to ensure its safety and compliance with state regulations.

Despite its historical significance and vital role in water supply, Huntsville Dam is currently assessed as being in poor condition with a high hazard potential. The last inspection in January 2021 revealed the need for maintenance and improvement to address safety concerns. The dam's emergency action plan (EAP) status and risk assessment measures are currently not up to date, highlighting the importance of ongoing monitoring and management to mitigate potential risks and ensure the safety of surrounding communities.

Given the critical role of Huntsville Dam in water resource management, efforts to address its condition and enhance safety measures are essential. Climate enthusiasts and water resource specialists should closely monitor updates on Huntsville Dam to support initiatives that promote infrastructure resilience and sustainable water supply management in the face of changing climate conditions and increasing demands on water resources.

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.
