Baker River Site 2 Dam Dam
Baker River Site 2 Dam
Baker River Site 2 Dam, also known as Hildreth Dam, is a state-owned structure located in Warren, New Hampshire. Built in 1965 by the USDA NRCS, this Earth dam serves the primary purpose of flood risk reduction along Berry Brook. Standing at a height of 68 feet and spanning 805 feet in length, the dam has a storage capacity of 2300 acre-feet and a surface area of 39 acres.
With a high hazard potential and fair condition assessment, Baker River Site 2 Dam is regulated by the NHDES Dam Bureau and undergoes regular inspections to ensure its safety and effectiveness. Despite its age, the dam continues to play a crucial role in mitigating flood risks in the region, with a maximum discharge capacity of 439 cubic feet per second. While the dam has not been modified in recent years, its emergency action plan is regularly reviewed and updated to meet guidelines and ensure preparedness for any potential risks.
For water resource and climate enthusiasts, Baker River Site 2 Dam represents a key infrastructure asset in the state's flood risk reduction strategy. As part of the Natural Resources Conservation Service's portfolio, this buttress-type dam has been instrumental in managing water levels and protecting downstream areas from flooding. With its location in Grafton County and a storage capacity of 2300 acre-feet, Baker River Site 2 Dam stands as a testament to effective water resource management and the importance of infrastructure resilience in the face of changing climate conditions.

About Baker River Site 2 Dam
Where does the data for Baker River Site 2 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 below 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.

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.
