Summary

Built in 1960 and designed by the USDA NRCS, this dam stands at a height of 29 feet and stretches 420 feet in length, providing a storage capacity of 139 acre-feet. Despite its significant role in mitigating flood risks, Martin (Pa-419) is classified as having a high hazard potential and is currently in poor condition, as indicated by a recent inspection report.

Managed by the Pennsylvania Department of Environmental Protection, this dam is regulated, permitted, inspected, and enforced by the state agency to ensure its safety and functionality. The dam's location within a regulated jurisdiction highlights the critical importance of maintaining its structural integrity to protect downstream communities from potential flooding events. As a water resource and climate enthusiast, staying informed about the condition and risk assessment of dams like Martin (Pa-419) is crucial for understanding the broader implications of climate change on our water infrastructure and the need for sustainable management practices to adapt to evolving environmental challenges.

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.
