Summary
1, located in Shallotte, North Carolina, is a key water resource managed by the local government for wastewater treatment. This lagoon, situated along the Shallotte River, plays a crucial role in maintaining water quality in the region. With a structural height of 18 feet and a hydraulic height of 15 feet, this earth dam was completed in 1970 and has a storage capacity of 100 acre-feet, with a normal storage level of 70 acre-feet.
The dam's primary purpose, classified as 'Other', underscores its significance in managing water resources in the area. With a hazard potential rated as 'High', regular inspections are conducted to ensure its structural integrity and overall condition. The last inspection in September 2018 deemed the dam to be in satisfactory condition, meeting regulatory standards set by the North Carolina Department of Environmental Quality, Division of Energy, Mineral, and Land Resources.
Climate and water resource enthusiasts monitoring the impact of infrastructure on water quality and management will find Shallotte Wastewater Lagoon No. 1 an important case study. The lagoon's role in wastewater treatment, its location along the Shallotte River, and its compliance with state regulations make it a critical asset in safeguarding the local environment. As efforts continue to maintain and monitor this essential water resource, its significance in the broader context of climate resilience and sustainable water management cannot be understated.

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.
