Summary
2, located in Shallotte, North Carolina, is a crucial water resource managed by the local government. The lagoon, completed in 1997, serves as a vital component in the treatment and disposal of wastewater from the surrounding area. Situated along the Shallotte River, this Earth-type dam stands at a hydraulic height of 22 feet, with a storage capacity of 240 acre-feet and a surface area of 12 acres.
Despite its satisfactory condition assessment as of September 2018, Shallotte Wastewater Lagoon No. 2 poses a high hazard potential due to its proximity to residential and commercial areas. Regular inspections, conducted every two years, help ensure the lagoon's structural integrity and safe operation. State regulatory agencies, including NCDEQ and DEMLR, oversee permitting, inspection, and enforcement activities related to this essential water infrastructure.
Enthusiasts of water resources and climate management will find Shallotte Wastewater Lagoon No. 2 a fascinating case study in sustainable wastewater treatment and environmental protection. Its strategic location, efficient design, and regulatory oversight highlight the importance of responsible water resource management in safeguarding public health and the surrounding ecosystem.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
