Summary

Completed in 1959, this earth dam stands at a height of 29 feet with a hydraulic height of 25 feet and a length of 680 feet. The dam has a storage capacity of 125 acre-feet and a maximum discharge of 1080 cubic feet per second.

Despite being classified as having low hazard potential, the risk assessment for SCS-Barnitz Creek Site-070 indicates a very high risk level, with a DSAC assigned date and a lack of emergency action plans or inundation maps. The dam has not been inspected since 1980, with an inspection frequency of 5 years, and its condition is currently listed as "Not Rated." The dam is equipped with a controlled spillway and a single outlet valve, but there are no associated structures or locks.

The presence of SCS-Barnitz Creek Site-070 serves as a critical flood risk reduction measure in the area, yet its high risk level and lack of recent inspections highlight the importance of continued monitoring and maintenance to ensure its effectiveness and safety for surrounding communities and the local environment.

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.
