Shirley Farm Hog Lagoon dam
Shirley Farm Hog Lagoon
Shirley Farm Hog Lagoon, located in Greene, North Carolina, is a private earth dam structure built in 1979 for purposes not specified in the data. 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.

About Shirley Farm Hog Lagoon
Where does the data for Shirley Farm Hog Lagoon come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card below for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.
