Indian Mills Dam dam
Indian Mills Dam
Indian Mills Dam, located in Shamong Township, New Jersey, is a significant earth dam completed in 1807 for recreational purposes. Situated on Muskingum Brook, the dam stands at a height of 11 feet and has a length of 600 feet, providing a storage capacity of 267 acre-feet. With a normal storage capacity of 160 acre-feet and a surface area of 40 acres, the dam plays a crucial role in the local ecosystem and water supply management.
Managed by the local government and regulated by the New Jersey Department of Environmental Protection, Indian Mills Dam has a satisfactory condition assessment and a significant hazard potential. The dam underwent its last inspection in September 2021, with a frequency of every 2 years. Despite its age, the dam continues to serve its recreational purpose while ensuring the safety and well-being of the surrounding communities. The dam's emergency action plan is regularly updated to meet guidelines and ensure preparedness in case of any unforeseen events.
Furthermore, Indian Mills Dam is located in Congressional District 03, New Jersey, represented by Andy Kim (D). The dam's maximum discharge capacity is 487 cubic feet per second, highlighting its importance in managing water flow and preventing flooding in the area. As a vital infrastructure asset, the dam's role in water resource management and climate resilience underscores the need for continued monitoring, maintenance, and risk assessment to safeguard the community and the environment.

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 Indian Mills Dam
Where does the data for Indian Mills 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.
