Monadnock Paper Indust Lag Dam dam
Monadnock Paper Indust Lag Dam
Monadnock Paper Indust Lag Dam, located in Bennington, New Hampshire, is a privately owned Earth dam completed in 1973 with a height of 14 feet and a length of 1050 feet. The dam serves a primary purpose of "Other" and has a storage capacity of 24.55 acre-feet, with a surface area of 4.06 acres. Despite having no spillway, the dam is classified as having a "Significant" hazard potential and a "Satisfactory" condition as of the last inspection in November 2017.
Managed by the NHDES Dam Bureau, the dam is subject to state regulations, permitting, inspections, and enforcement. The risk assessment for Monadnock Paper Indust Lag Dam is rated as "High (2)", indicating a need for strong risk management measures. The surrounding area, which includes Hillsborough County, New Hampshire, falls within the jurisdiction of the New England District of the US Army Corps of Engineers.
This dam is a vital component of water resource management in the region, highlighting the intersection of industry, environmental regulations, and climate resilience. With its significant hazard potential and high risk rating, ongoing monitoring and maintenance efforts are crucial to ensure the safety and security of the dam and the surrounding community.
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 Monadnock Paper Indust Lag Dam
Where does the data for Monadnock Paper Indust Lag 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.
