Clark Pond West Dam dam
Clark Pond West Dam
Clark Pond West Dam, located in Auburn, New Hampshire, serves as a vital water supply structure managed by the local government. Built in 1811, this earth dam stands at a height of 9 feet and has a storage capacity of 100 acre-feet. With a spillway width of 57 feet and a maximum discharge of 1677 cubic feet per second, the dam plays a crucial role in managing water resources in the region.
Despite being classified as having a low hazard potential, the dam is rated in fair condition with a moderate risk assessment. Regular inspections are conducted by the New Hampshire Department of Environmental Services Dam Bureau, ensuring that the structure meets safety standards. The surrounding area boasts a surface area of 40 acres and a drainage area of 14.5 square miles, making it an important feature in the local hydrological landscape.
For water resource and climate enthusiasts, Clark Pond West Dam offers a fascinating case study in dam management and water supply infrastructure. As a key component in the region's water resource system, this historic earth dam continues to play a vital role in providing water to the community while maintaining a balance between water supply needs and environmental conservation. Its location in Rockingham County, New Hampshire, makes it a prime example of how dam structures contribute to sustainable water management practices in the face of changing climate conditions.

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 Clark Pond West Dam
Where does the data for Clark Pond West 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.
