Knight Meadow Pond Dam dam
Knight Meadow Pond Dam
Knight Meadow Pond Dam in Webster, New Hampshire, is a state-regulated structure with a primary purpose of recreation. Built in 1966, this earth dam stands at a height of 9 feet and has a length of 90 feet, creating a reservoir with a storage capacity of 483 acre-feet. The dam is situated on Knight Meadow Brook, within the Merrimack County of New Hampshire, and is owned by the state.
Despite being classified as having a low hazard potential, the dam's condition is assessed as fair, with the last inspection in June 2017. The structure boasts a moderate risk assessment rating, indicating the need for careful monitoring and risk management measures. With a drainage area of 3.7 square miles and a maximum discharge rate of 748 cubic feet per second, Knight Meadow Pond Dam plays a crucial role in water resource management and flood control in the region.
Enthusiasts of water resources and climate will find Knight Meadow Pond Dam an intriguing example of a recreational dam with both recreational and practical functions. Its design and construction reflect the engineering efforts to balance water storage needs with environmental considerations, making it a vital component of the local landscape and ecosystem. As climate change continues to impact water resources, structures like Knight Meadow Pond Dam will play a crucial role in adapting to and mitigating the effects of changing weather patterns on the region's water supply and flood control efforts.

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 Knight Meadow Pond Dam
Where does the data for Knight Meadow Pond 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 Low 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.
