Manhanock Pond dam
Manhanock Pond
Manhanock Pond, located in Sangerville, Maine, is a picturesque body of water created in 1878 primarily for recreational purposes. The dam that forms the pond is a concrete structure with a height of 10 feet, providing a storage capacity of 2535 acre-feet and a surface area of 420 acres. The pond is fed by the Carlton Stream and serves as a popular spot for fishing, boating, and other outdoor activities for locals and visitors alike.
Managed by the local government and regulated by the Maine Emergency Management Agency, Manhanock Pond has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. The dam has a spillway width of 110 feet and is inspected every 12 months to ensure its safety and functionality. While no major modifications or risk management measures are reported, the pond remains a tranquil and inviting destination for water resource and climate enthusiasts looking to enjoy the natural beauty and recreational opportunities it offers in the heart of Piscataquis County.
With its historical significance dating back over a century, Manhanock Pond continues to be a vital resource for flood risk reduction and water recreation in the region. As climate change and water resource management become increasingly important topics, the careful monitoring and maintenance of this dam and reservoir provide a valuable example of how local governments can balance the need for safety, environmental stewardship, and community enjoyment in managing their water resources.

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 Manhanock Pond
Where does the data for Manhanock Pond 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.
