Summary

Completed in 1967, this earth-type dam stands at a height of 57 feet and spans 700 feet, with a storage capacity of 1395 acre-feet. The dam's primary purpose is flood risk reduction, serving to protect the surrounding area from potential inundation during heavy rainfall events.

Despite its critical role in flood mitigation, Nanticoke Creek Site 13 Dam poses a high hazard potential, although its condition assessment is listed as "Not Rated." The dam's spillway, of uncontrolled type, boasts a width of 331 feet to safely manage excess water flow. The dam's inspection frequency is every two years, with the last inspection conducted in May 2020. While the risk assessment indicates a moderate level of risk (3), further details on risk management measures are not currently available.

In the realm of water resource and climate enthusiasts, the Nanticoke Creek Site 13 Dam serves as a noteworthy example of infrastructure designed to safeguard communities from flooding events. With its historical significance and vital role in protecting the surrounding area, this dam highlights the importance of proactive risk assessment and maintenance to ensure the safety and resilience of water resource structures in the face of changing climate conditions.

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.
