Summary

Managed by the Pennsylvania Department of Environmental Protection, this earth dam stands at 22 feet in height and spans 850 feet in length, with a storage capacity of 154 acre-feet. Despite its importance for water supply, Martindale poses a high hazard potential with a poor condition assessment, making its maintenance and upkeep a top priority.

The dam's primary purpose of water supply serves the local community in Cambria County, Pennsylvania, ensuring a reliable source of water for various needs. With a drainage area of 1.17 square miles, Martindale's reservoir covers 9 acres and has a normal storage capacity of 114 acre-feet. However, ongoing inspections and monitoring are necessary to address its poor condition and mitigate potential risks associated with its high hazard potential.

As one of the essential structures in the region, Martindale requires regular assessment and maintenance to uphold its integrity and safety standards. The dam's association with the Baltimore District and its status as a state-regulated water resource underscore the significance of ensuring its operational efficiency and structural stability for the surrounding community's water supply needs.

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.
