Summary
This earth dam, supported by stone core types and a soil foundation, stands at a structural height of 12 feet with a storage capacity of 176 acre-feet. Despite being uncontrolled, the spillway and outlet gates maintain a low hazard potential and satisfactory condition as of the last inspection in 2008.
Situated within the Wilmington District, this dam has a moderate risk assessment rating and is not regulated by the state. With no associated structures and an absence of federal agency involvement in funding, designing, or regulating, Yow-Williams Lake Dam remains an essential part of the Onslow community's water resource management. Climate and water enthusiasts can appreciate the dam's contribution to the region's water storage and recreational opportunities, while also recognizing the need for periodic inspections and maintenance to ensure its continued safety and functionality for future generations.
Walter B. Jones, the representative for the district, oversees the area where Yow-Williams Lake Dam stands, highlighting the intersection of local governance and environmental stewardship. As the dam continues to play a crucial role in water conservation and outdoor recreation, ongoing efforts to monitor and address any potential risks associated with its operation will be essential to preserving its value and integrity in the years to come.

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.
