Pea Porridge Pond Middle & Little dam
Pea Porridge Pond Middle & Little
Pea Porridge Pond Middle & Little, located in Madison, New Hampshire, is a picturesque water resource managed by the local government for recreational purposes. Built in 1966, this earth dam stands at a height of 17 feet and has a storage capacity of 406 acre-feet, making it a significant feature in the area. The dam regulates the flow of water from the Pea Porridge Pond, which covers a surface area of 49 acres and has a drainage area of 2.74 square miles.
Despite being categorized as having a significant hazard potential, the dam is currently assessed to be in fair condition as of May 2016. Regular inspections are conducted, with the last one taking place in June 2020, to ensure the safety and stability of the structure. The dam's spillway type is uncontrolled, with a width of 17 feet, and a maximum discharge capacity of 895 cubic feet per second. The risk assessment for the dam is moderate, indicating a need for ongoing monitoring and management measures to mitigate potential hazards.
Water resource and climate enthusiasts visiting Pea Porridge Pond Middle & Little can appreciate the beauty of the surrounding area while also gaining insight into the management practices involved in maintaining a crucial piece of infrastructure. With its recreational purposes and environmental significance, this dam serves as a focal point for both local residents and visitors interested in the intersection of water resources and climate resilience.
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 Pea Porridge Pond Middle & Little
Where does the data for Pea Porridge Pond Middle & Little 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 Significant 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.
