Maskells Mill Pond Dam dam
Maskells Mill Pond Dam
Maskells Mill Pond Dam, located in Salem, New Jersey, is a state-regulated structure on the Upper Branch Stowe Creek, completed in 1955 with a primary purpose of recreation. This earth dam stands at a height of 13 feet and spans 350 feet in length, providing a storage capacity of 128 acre-feet and covering a surface area of 19 acres. The dam has a significant hazard potential and has been assessed to be in poor condition as of September 2021.
Despite its recreational significance, Maskells Mill Pond Dam requires regular inspections and enforcement to ensure its safety and compliance with state regulations. The dam is part of the Lower Alloways Creek Township and falls under the jurisdiction of the New Jersey Department of Environmental Protection (NJDEP). The dam's last inspection was conducted in September 2021, with a frequency of every two years. The dam's Emergency Action Plan (EAP) was last revised in October 2013, highlighting the need for updated emergency protocols and risk management measures.
Water resource and climate enthusiasts will find Maskells Mill Pond Dam an intriguing structure with its historical significance and recreational value, set against the backdrop of environmental regulations and safety concerns. Its location within the Baltimore District and Congressional District 02 of New Jersey adds layers of complexity to its management and oversight. As discussions around water management and infrastructure continue, the condition and maintenance of Maskells Mill Pond Dam serve as a focal point for balancing recreational use with safety and environmental protection 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 Maskells Mill Pond Dam
Where does the data for Maskells Mill 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.
