Roosevelt Park Dam dam
Roosevelt Park Dam
Roosevelt Park Dam in Middlesex, New Jersey, is a vital structure along the South Branch Rahaway River, serving as a key recreational resource for the local community. Owned by the local government, this earth dam stands at a height of 7.7 feet and has a storage capacity of 26 acre-feet. With a surface area of 11 acres and a drainage area of 1.2 square miles, the dam plays a crucial role in managing water resources in the region.
Maintained by the New Jersey Department of Environmental Protection, Roosevelt Park Dam has been deemed to have a significant hazard potential but is currently in satisfactory condition. The dam offers a serene backdrop for outdoor activities and wildlife observation, making it a popular spot for enthusiasts interested in water resources and climate studies. With its strategic location in Edison Township and close oversight by regulatory agencies, the dam serves as a prime example of sustainable infrastructure that balances recreational use with environmental stewardship.
With regular inspections and a well-prepared emergency action plan, Roosevelt Park Dam ensures the safety of nearby communities while providing a picturesque setting for residents and visitors to enjoy. As part of ongoing risk management measures, the dam continues to be a focal point for water resource and climate enthusiasts seeking to understand the intersection of infrastructure, nature, and public recreation in a changing climate.

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.
Plan around the weather

About Roosevelt Park Dam
Where does the data for Roosevelt Park 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.
