Whitewater Brook Dam dam
Whitewater Brook Dam
Whitewater Brook Dam in Claremont, New Hampshire, stands as a vital local government-owned structure designed for water supply purposes. Completed in 1968, this Earth-type dam boasts a height of 95 feet and a length of 425 feet, with a storage capacity of 665 acre-feet. Situated on the White Water Brook, it plays a crucial role in regulating water flow and ensuring a stable water supply for the region.
With a high hazard potential but a satisfactory condition assessment, Whitewater Brook Dam is closely monitored by the New Hampshire Department of Environmental Services Dam Bureau, showcasing a commitment to safety and regulatory compliance. The dam's uncontrolled spillway, with a width of 120 feet, is designed to handle maximum discharges of up to 9695 cubic feet per second, ensuring effective flood control measures. Despite its moderate risk level, the dam's emergency action plan and risk management measures are essential components in safeguarding the surrounding community from potential hazards.
Overall, Whitewater Brook Dam stands as a significant infrastructure asset in Sullivan County, New Hampshire, serving as a critical water resource for the area. Its strategic location, design features, and regulatory oversight highlight its importance in water management and climate resilience efforts, making it a valuable asset for water resource and climate enthusiasts alike.
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 Whitewater Brook Dam
Where does the data for Whitewater Brook 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.
