Upper Peverly Pond Dam dam
Upper Peverly Pond Dam
Upper Peverly Pond Dam, located in Rockingham, New Hampshire, is a Federal-owned structure regulated by the NHDES Dam Bureau. Constructed in 1935, this Earth-type dam stands at a height of 11 feet and spans 400 feet in length, impounding water from Peverly Brook. The dam serves multiple purposes, with a normal storage capacity of 60 acre-feet and a maximum storage capacity of 140 acre-feet.
Managed by the Fish and Wildlife Service, Upper Peverly Pond Dam has a low hazard potential and is currently assessed to be in fair condition as of September 2012. It has undergone modifications in 1998 and 2000 related to its hydraulic components. The dam is equipped with outlet gates for controlled water release and valve operation. While the dam's primary purpose is listed as 'Other', it plays a crucial role in water resource management and environmental conservation efforts in the region.
With its serene surroundings and vital water storage capabilities, Upper Peverly Pond Dam stands as a testament to the importance of sustainable water resource management and climate resilience. As enthusiasts in this field, understanding the infrastructure and regulatory aspects of such dams is crucial in ensuring their safety, functionality, and contribution to the overall ecosystem health.

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 Upper Peverly Pond Dam
Where does the data for Upper Peverly 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.
