About this dam

Mill Pond

Mill Pond, located in Knox, Maine, is a captivating fish and wildlife pond with a rich history dating back to its completion in 1920. This private concrete dam stands at a height of 15 feet, providing a storage capacity of 210 acre-feet and a surface area of 33 acres. The pond serves as a recreational spot and a haven for various wildlife species, making it an essential resource for the local ecosystem.

Maintained and regulated by the Maine Emergency Management Agency (MEMA), Mill Pond has a low hazard potential and is inspected regularly to ensure its structural integrity. With a spillway width of 10 feet and a drainage area of zero, the pond's primary purpose is to support fish and wildlife populations in the area. Additionally, the dam's location near Allen Brook adds to its natural beauty and ecological significance, attracting water resource and climate enthusiasts to enjoy its peaceful surroundings and diverse wildlife.

As a cherished feature in the New England District, Mill Pond continues to provide a vital habitat for various species while offering recreational opportunities for visitors. Its historical significance, combined with its role in supporting local biodiversity, makes it a valuable asset for both the community and the environment. With proper management and maintenance, Mill Pond stands as a beacon of conservation and enjoyment for all who appreciate the intersection of water resources and climate preservation.

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.

FAQ

About Mill Pond

Where does the data for Mill 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.
