Bog Brook Pond Dam dam
Bog Brook Pond Dam
Bog Brook Pond Dam, also known as Palazzi Pond Dam, is a privately owned structure located in Springfield, New Hampshire. This earth dam, completed in 1957, serves primarily for recreational purposes and stands at a height of 18 feet with a length of 700 feet. The dam has a storage capacity of 144.1 acre-feet, with a normal storage level of 64.7 acre-feet, covering a surface area of 17.6 acres.
Managed by the NHDES DAM BUREAU, the dam is state regulated, inspected, and enforced to ensure its safety and compliance with regulations. In terms of risk assessment, it has been classified as having a moderate risk level. The dam's hazard potential is considered low, and its condition assessment is satisfactory. While the dam does not have a designated Emergency Action Plan (EAP) or inundation maps prepared, it meets the necessary guidelines for operation.
With Bog Brook flowing through it, the dam plays a crucial role in the local water resource management and contributes to the environmental landscape of the area. Enthusiasts interested in water resources and climate can appreciate the significance of this structure in providing recreational opportunities while also being mindful of its maintenance and regulatory oversight to ensure safety and sustainability for the surrounding community and ecosystem.
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 Bog Brook Pond Dam
Where does the data for Bog Brook 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.
