Ceva Lake Dam dam
Ceva Lake Dam
Ceva Lake Dam, located in Ewing, New Jersey, is a state-owned structure that serves primarily for recreation purposes. Built in 1920, this earth dam stands at a height of 14 feet and has a length of 300 feet, providing a storage capacity of 15 acre-feet. Situated on Branch Shabakunk Creek, the dam has a drainage area of 0.27 square miles and a surface area of 5 acres, making it a significant water resource for the area.
Managed by the New Jersey Department of Environmental Protection (NJDEP), Ceva Lake Dam is regulated, inspected, and enforced by the state agency to ensure its safety and functionality. The dam has been assessed as being in satisfactory condition, with a significant hazard potential. Regular inspections are conducted, with the last one taking place in October 2021, and an emergency action plan is in place, meeting the necessary guidelines. The dam's risk assessment and management measures are currently under review.
As a key component of the water infrastructure in Mercer County, New Jersey, Ceva Lake Dam plays a crucial role in water management and recreational activities in the area. With its historical significance and ongoing maintenance efforts, this dam serves as a vital resource for water enthusiasts and climate advocates alike, highlighting the importance of sustainable water resource management and dam safety practices 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 Ceva Lake Dam
Where does the data for Ceva Lake Dam 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.
