Milton Lake Dam dam
Milton Lake Dam
Milton Lake Dam, located in Rahway, New Jersey, is a concrete structure completed in 1937 primarily used for recreation purposes. With a height of 10 feet and a length of 204 feet, the dam has a normal storage capacity of 15 acre-feet and a maximum storage of 30 acre-feet. It is situated on the Robins Branch Rahway River and falls under the regulatory oversight of the New Jersey Department of Environmental Protection, ensuring that the dam is inspected, permitted, and enforced to meet safety standards.
Despite its satisfactory condition assessment as of November 2021, Milton Lake Dam poses a significant hazard potential due to its structural features and location. Regular inspections are conducted every two years to assess the dam's safety and integrity. The dam has not undergone any modifications since its completion, and its emergency action plan was last revised in January 2011. The dam's risk assessment, management measures, and inundation maps are yet to be fully documented, highlighting the need for proactive monitoring and preparedness efforts.
As an essential water resource structure in Union County, Milton Lake Dam remains a focal point for water resource and climate enthusiasts. Its historical significance, recreational value, and hydraulic functions contribute to the local ecosystem and community resilience. With ongoing regulatory oversight and inspection protocols, Milton Lake Dam ensures the safety and sustainability of water management practices in the region, serving as a testament to effective dam infrastructure management in New Jersey.

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 Milton Lake Dam
Where does the data for Milton 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.
