Summary
This dam stands at a structural height of 25 feet with a hydraulic height of 23 feet, providing a storage capacity of 50.8 acre-feet and covering a surface area of 4.5 acres. The dam is regulated by the North Carolina Dam Safety Program and undergoes regular inspections to ensure its structural integrity.
Despite being classified as having a "High" hazard potential, the condition assessment of Olde Sycamore Wwtp Lagoon Dam was rated as "Fair" during its last inspection in December 2019. The emergency action plan status, risk assessment, and risk management measures for the dam are currently unknown. While the dam does not have a spillway or outlet gates, its inspection frequency is set at every 2 years to monitor any potential changes in its condition. Additionally, the dam is not under the jurisdiction of any federal agency, with the Wilmington District serving as the local USACE district.
For water resource and climate enthusiasts, Olde Sycamore Wwtp Lagoon Dam presents an intriguing case study in private dam ownership and regulation. The dam's location along Duck Creek-Tr in North Carolina adds to its significance within the local water management landscape. With its relatively modest storage capacity and surface area, the dam's role in water resource management and flood control in the region may be further explored. As efforts to address climate change and improve water infrastructure continue, understanding the condition and risk profile of dams like Olde Sycamore Wwtp Lagoon Dam becomes increasingly important in ensuring the safety and sustainability of our water resources.

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.
