Century Village Dam dam
Century Village Dam
The Century Village Dam, located in Londonderry, New Hampshire, was completed in 1988 and serves primarily for recreation purposes. Owned privately, the dam is regulated by the NHDES Dam Bureau and is subject to state jurisdiction, permitting, inspection, and enforcement. With a height of 8 feet and a length of 200 feet, the dam has a storage capacity of 50 acre-feet and covers a surface area of 7 acres.
Despite being classified as having a significant hazard potential, the dam is currently assessed to be in fair condition. The last inspection in August 2017 found the structure to be functioning adequately. Although the dam has an uncontrolled spillway type and no outlet gates, its risk assessment is categorized as moderate. The surrounding area is at risk of inundation, but no specific measures for risk management or emergency action planning have been disclosed.
Water resource and climate enthusiasts interested in the Century Village Dam will find a unique case study in dam management and recreational use in New Hampshire. The dam's presence along an unnamed stream in Rockingham County highlights the importance of regulating private dams to ensure public safety and environmental protection. As a significant hazard potential structure, the Century Village Dam serves as a reminder of the importance of ongoing maintenance and risk assessment in the management of water resources and infrastructure.

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 Century Village Dam
Where does the data for Century Village 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.
