Jordan Mill Privilege dam
Jordan Mill Privilege
Jordan Mill Privilege is a historic structure located in Cumberland, Maine, along the Royal River. Built in 1770, this concrete dam serves multiple purposes including fire protection, stock maintenance, and serving as a small fish pond. With a height of 12 feet and a storage capacity of 150 acre-feet, it covers a surface area of 25 acres and drains a 13-square mile watershed area. Despite its age, the dam is in fair condition and has a low hazard potential.
Managed by a private owner, Jordan Mill Privilege is regulated by the Maine Emergency Management Agency, ensuring that it meets state permitting, inspection, and enforcement requirements. The dam's primary purpose of providing fire protection and supporting recreational activities highlights its importance to the local community. With a spillway width of 12 feet and a history dating back over two centuries, the Jordan Mill Privilege is a key feature in the region's water resource management and climate adaptation efforts.
For water resource and climate enthusiasts, the Jordan Mill Privilege offers a glimpse into the historical significance of water infrastructure in Maine. Its unique design and functionality make it an important asset for maintaining water levels, protecting against fires, and supporting local wildlife. With its low hazard potential and fair condition assessment, the dam continues to play a vital role in the region's water management strategies. As climate change impacts become more pronounced, structures like Jordan Mill Privilege serve as crucial components in ensuring water security and resilience for communities in Maine.

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 Jordan Mill Privilege
Where does the data for Jordan Mill Privilege 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.
