New Jersey No Name #31 Dam dam
New Jersey No Name #31 Dam
New Jersey No Name #31 Dam, located in Clinton Township, Hunterdon, New Jersey, is a state-regulated earth dam situated on Cramers Creek. Standing at a height of 23 feet and stretching 550 feet in length, this dam serves a primary purpose of "Other" with a storage capacity of 40 acre-feet. With a drainage area of 2.3 square miles and a surface area of 7 acres, this dam plays a vital role in water resource management in the region.
Despite its satisfactory condition assessment as of October 2020, New Jersey No Name #31 Dam has a high hazard potential, highlighting the importance of regular inspections and maintenance. The dam is subject to state regulation, with the New Jersey Department of Environmental Protection overseeing permitting, inspection, and enforcement activities. The dam's Emergency Action Plan was last revised in April 2021, emphasizing the need for preparedness and risk management measures to ensure the safety and security of the surrounding area in the event of an emergency.
Congressional District 07, represented by Tom Malinowski, encompasses the location of the dam, underscoring the significance of political and community involvement in water resource and climate-related issues. With its critical role in water storage and management, New Jersey No Name #31 Dam serves as a key infrastructure asset in the region, requiring ongoing attention and resources to maintain its functionality and safety for the benefit of local residents and the environment.
Dam data reference
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 New Jersey No Name #31 Dam
Where does the data for New Jersey No Name #31 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.
