Massachusetts Bog dam
Massachusetts Bog
Massachusetts Bog, located in Franklin, Maine, is a private Fish and Wildlife Pond dating back to 1970. With a dam height of 16 feet and a storage capacity of 264 acre-feet, this timber crib dam serves multiple purposes including fish and wildlife habitat, recreation, and more. The dam, with a hydraulic height of 12 feet, plays a crucial role in maintaining the normal storage of 253 acre-feet across its 30-acre surface area.
Managed by the state regulatory agency MEMA, Massachusetts Bog is inspected regularly with a fair condition assessment reported in August 2016. Despite its low hazard potential, the dam is subject to state jurisdiction, permitting, and enforcement to ensure its continued safety and functionality. With its scenic location along the Massachusetts Bog Stream, this dam provides important ecological benefits while also offering recreational opportunities for enthusiasts and climate advocates alike.
For water resource and climate enthusiasts, Massachusetts Bog represents a valuable ecosystem and recreational area that highlights the importance of proper dam management and maintenance. As a state-regulated facility, this timber crib dam serves as a vital habitat for fish and wildlife, while also offering opportunities for outdoor activities. With ongoing inspections and a focus on safety and sustainability, Massachusetts Bog stands as a testament to the intersection of nature, water resources, and responsible environmental stewardship.
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 Massachusetts Bog
Where does the data for Massachusetts Bog 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.
