Summary
The lagoon is situated on Beaman Farm Road near Howell Swamp, with a hydraulic height of 15.14 feet and a structural height of 16.14 feet. It has a storage capacity of 28 acre-feet and covers a surface area of 2 acres, serving a drainage area of 5 acres. Despite being inspected in December 2008, its condition assessment remains unrated.
With a significant hazard potential, Shirley Farm Hog Lagoon stands as a notable water resource infrastructure in the area. The dam's primary purpose and design are categorized as "Other," indicating a unique function within the region's water management system. While the lagoon has not undergone state regulation or permitting, it does receive periodic inspections to ensure its operational integrity. The surrounding community benefits from this structure's role in managing water flow and storage for agricultural or environmental purposes.
As water resource and climate enthusiasts explore the intricate network of dams and lagoons in North Carolina, Shirley Farm Hog Lagoon emerges as a key feature in Greene County. Its construction in the late 1970s reflects a period of heightened infrastructure development to address water management needs in the region. Despite its relatively small size, this earth dam structure plays a crucial role in controlling water levels and ensuring efficient drainage in the Howell Swamp area, demonstrating the diverse array of water resource systems that contribute to the region's environmental sustainability.

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.
