Hackettstown Res. Dam dam
Hackettstown Res. Dam
Hackettstown Res. Dam in Mount Olive Township, New Jersey, stands as a critical structure for water supply on Mine Brook. This concrete dam, with a height of 38 feet and a length of 285 feet, provides a storage capacity of 68 acre-feet and covers a surface area of 48 acres. The dam is regulated by the New Jersey Department of Environmental Protection and undergoes regular inspections to ensure its structural integrity and operational efficiency.
Despite its importance in water supply, Hackettstown Res. Dam is classified as having a high hazard potential and is currently assessed as being in poor condition. The last inspection in April 2019 highlighted the need for improvements to meet safety standards. To address these concerns, the dam's Emergency Action Plan (EAP) was last revised in July 2020, but further measures may be required to enhance risk management and ensure the dam's resilience in the face of potential emergencies.
As water resource and climate enthusiasts closely monitor the state of dams like Hackettstown Res. Dam, attention is increasingly drawn to the need for ongoing maintenance and modernization to mitigate risks and safeguard water supplies. With its vital role in the region's water infrastructure, efforts to improve the dam's condition and enhance its safety protocols are essential for ensuring the long-term sustainability of water resources in the area.

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 Hackettstown Res. Dam
Where does the data for Hackettstown Res. 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 High 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.
