Jacksonville Lts-South Storage Lagoon dam
Jacksonville Lts-South Storage Lagoon
The Jacksonville Lts-South Storage Lagoon in North Carolina is a key component in flood risk reduction efforts in the region. Completed in 2009, this earth dam structure serves as a crucial storage area for excess water during periods of heavy rainfall, helping to mitigate potential flooding in the surrounding area. The dam is regulated by the NCDEQ Dam Safety Program and undergoes regular inspections to ensure its structural integrity and effectiveness in flood control.
With a high hazard potential but a satisfactory condition assessment as of September 2018, the Jacksonville Lts-South Storage Lagoon is a vital piece of infrastructure in the battle against water-related emergencies. The dam is designed to handle the storage and discharge of water, with a focus on flood risk reduction as its primary purpose. Despite its importance, the dam does not have associated structures and relies on its own design and capabilities to fulfill its role in protecting the community.
Located in Onslow County, North Carolina, this dam is situated at a latitude of 34.7625 and a longitude of -77.5417. It falls under the jurisdiction of the Wilmington District of the USACE and is subject to state regulation, permitting, inspection, and enforcement. As climate change continues to impact water resources and weather patterns, structures like the Jacksonville Lts-South Storage Lagoon will play an increasingly crucial role in safeguarding communities against the threats of flooding and water-related disasters.
Dam data reference
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.

About Jacksonville Lts-South Storage Lagoon
Where does the data for Jacksonville Lts-South Storage 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.
