Jones Pond dam
Jones Pond
Jones Pond in Hancock, Maine, is a privately owned reservoir that serves multiple purposes, including flood risk reduction, fish and wildlife habitat, and recreation. Built in 1920, this concrete dam stands at a height of 7 feet and has a hydraulic height of 5 feet. With a storage capacity of 4408 acre-feet and a surface area of 467 acres, Jones Pond plays a crucial role in managing water resources in the area.
Managed by the Maine Emergency Management Agency, Jones Pond is under state jurisdiction and is subject to regulation, permitting, inspection, and enforcement. Despite its low hazard potential, the condition of the dam is currently not rated. The reservoir's spillway width is 15 feet, and it is equipped to handle potential emergencies effectively. While the dam has not been modified in recent years, it is important for water resource and climate enthusiasts to stay informed about its risk management measures and emergency preparedness protocols.
Located near Jones Stream, this significant water infrastructure is a key component of flood risk reduction efforts in the region. With its historical significance and multifaceted purposes, Jones Pond serves as a valuable asset for both the local community and the broader ecosystem. As climate change continues to pose challenges for water management, understanding and monitoring the condition of dams like Jones Pond is essential for ensuring the safety and sustainability of water resources in the area.

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.
Plan around the weather

About Jones Pond
Where does the data for Jones 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.
