Bethlehem Sewage Lagoon Dam dam
Bethlehem Sewage Lagoon Dam
The Bethlehem Sewage Lagoon Dam is a significant earth dam located in Grafton County, New Hampshire. Built in 1985, this dam serves a primary purpose other than water storage, with a height of 13 feet and a length of 2108 feet. The dam is owned by the local government and is regulated by the NHDES Dam Bureau, ensuring that it meets state inspection, enforcement, and permitting requirements.
With a storage capacity of 26 acre-feet, the Bethlehem Sewage Lagoon Dam plays a crucial role in managing wastewater in the area. Despite its satisfactory condition assessment, the dam is classified as having a significant hazard potential, warranting regular inspections and potential risk management measures. The surrounding community, including residents and water resource enthusiasts, can rest assured that the dam is being closely monitored to ensure public safety and environmental protection.
As a key infrastructure in Bethlehem, New Hampshire, the Bethlehem Sewage Lagoon Dam represents a vital component of the local water resource management system. With its strategic location and state regulatory oversight, this dam serves as a reminder of the importance of maintaining and monitoring critical infrastructure to safeguard against potential risks and ensure the continued availability of clean water for the community.

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 Bethlehem Sewage Lagoon Dam
Where does the data for Bethlehem Sewage Lagoon 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.
