City Of Wilmington Sewage Lagoon dam
City Of Wilmington Sewage Lagoon
The City of Wilmington Sewage Lagoon is a gravity dam located in New Castle, Delaware, along the Delaware River. With a height of 20.95 feet and a storage capacity of 1370 acre-feet, this dam serves as a vital piece of infrastructure for wastewater management in the area. Despite its high hazard potential, the dam is currently assessed to be in fair condition as of 2008.
The primary purpose of the City of Wilmington Sewage Lagoon is listed as "Other," indicating its role in managing wastewater and preventing pollution in the surrounding environment. The dam's structural design includes earth and gravity components, with a buttress core type. With a surface area of 33.16 acres and a drainage area of 0.29 square miles, this dam plays a crucial role in safeguarding water resources and maintaining proper sewage treatment protocols.
Although the dam lacks a spillway and outlet gates, it is still equipped to handle high-risk scenarios and emergency situations. With a risk assessment rating of "High (2)," the City of Wilmington Sewage Lagoon stands as a critical piece of infrastructure for the local community, ensuring the proper management of sewage and upholding environmental standards in the region.

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 City Of Wilmington Sewage Lagoon
Where does the data for City Of Wilmington Sewage 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.
