About this dam

Jacksonville Waste Water Lagoon

The Jacksonville Waste Water Lagoon, also known as the Land Treatment Facility Storage Lagoon, is a crucial water resource infrastructure owned by the local government in Onslow, North Carolina. This lagoon, completed in 1997 and located near Southwest Creek, serves a primary purpose of waste water treatment. It has a structural height of 15 feet and a hydraulic height of 10 feet, with a maximum storage capacity of 15 feet and a normal storage capacity of 12 feet. With a surface area of 500 square feet, this lagoon plays a vital role in managing water resources in the region.

Regulated by the North Carolina Department of Environmental Quality (NCDEQ), this lagoon has undergone regular inspections to ensure its satisfactory condition and high hazard potential is managed effectively. The last inspection in September 2018 confirmed the lagoon's overall satisfactory state. Despite its high hazard potential, the lagoon's emergency action plan (EAP) status and risk assessment details remain unclear, indicating a potential area for further improvement in emergency preparedness and risk management. With its critical role in waste water treatment and water resource management, the Jacksonville Waste Water Lagoon continues to be an essential piece of infrastructure in Onslow, North Carolina.

Overall, the Jacksonville Waste Water Lagoon stands as a key water resource infrastructure in Onslow County, North Carolina, ensuring effective waste water treatment and management in the region. With its high hazard potential and satisfactory condition, continuous monitoring and improvement in emergency preparedness and risk management are essential to maintain the lagoon's functionality and reliability. As a regulated facility by the NCDEQ, the lagoon plays a crucial role in safeguarding water resources and environmental quality in the area, making it a vital asset for climate and water resource enthusiasts to monitor and support.

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 Jacksonville Waste Water Lagoon

Where does the data for Jacksonville Waste Water 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 High 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.
