About this dam

Robinette Hog Lagoon

Robinette Hog Lagoon is a privately-owned water resource located in Marston, North Carolina. This Earth-type dam was completed in 1994 and serves a primary purpose of "Other," with a storage capacity of 84 acre-feet. The lagoon has a hydraulic height of 28 feet and a structural height of 30 feet, situated on the Chock Ck-Tr stream within the Wilmington District of the US Army Corps of Engineers.

With a surface area of 7 acres and a drainage area of 7.3 acres, Robinette Hog Lagoon plays a significant role in water management in the region. Despite being classified as having a "Fair" condition assessment as of 2017, the dam is deemed to have a "Significant" hazard potential. The lagoon is regulated and permitted by the North Carolina Department of Environmental Quality's Dam Safety Program, ensuring that it is regularly inspected, enforced, and maintained to meet safety standards.

For water resource and climate enthusiasts, Robinette Hog Lagoon represents a crucial piece of infrastructure in the Richmond County area. Its role in flood control, water storage, and environmental protection highlights the importance of proper dam management in safeguarding both human communities and natural ecosystems. As a privately-owned facility, it showcases the collaboration between public regulatory agencies and private entities in ensuring the sustainable use of water resources for the benefit of all stakeholders.

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.

FAQ

About Robinette Hog Lagoon

Where does the data for Robinette 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 above 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.
