Upper Pond Dam dam
Upper Pond Dam
Upper Pond Dam, located in Middletown, New Jersey, serves as a vital recreational resource along the Nut Swamp Brook-TR. Managed by a private owner, this earth dam is regulated by the New Jersey Department of Environmental Protection, ensuring its compliance with state guidelines for inspection and enforcement. Despite its poor condition assessment in 2017, the dam's significant hazard potential highlights the need for ongoing risk management measures and emergency preparedness.
The dam's primary purpose for recreation attracts water resource and climate enthusiasts to its Monmouth County location. With a history dating back to an unknown completion year, Upper Pond Dam's structural details, including height, volume, and storage capacity, remain unspecified. However, its inspection frequency of every two years and designation as a state-regulated structure underscore the importance of monitoring and maintenance to ensure public safety and environmental protection.
As the dam's condition assessment reveals room for improvement, the significance of Upper Pond Dam in providing recreational opportunities to the community underscores the need for continued oversight and risk mitigation strategies. With its location along Nut Swamp Brook-TR and under the jurisdiction of the New Jersey DEP, efforts to address the dam's poor condition and enhance its safety measures will be crucial in maintaining its role as a valuable water resource in Monmouth County.

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 Upper Pond Dam
Where does the data for Upper Pond 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.
