About this dam

Pingree Pond

Pingree Pond, located in Piscataquis County, Maine, is a private water resource managed for hydroelectric power generation, fish and wildlife conservation, and recreational activities. The dam, completed in 1900, is primarily made of concrete and spans 105 feet in length with a height of 16 feet. The reservoir has a storage capacity of 117 acre-feet and covers a surface area of 26 acres, serving as a habitat for various aquatic species and a popular spot for outdoor enthusiasts.

Owned and regulated by private entities, Pingree Pond is under the jurisdiction of the Maine Emergency Management Agency (MEMA) for permitting, inspection, and enforcement purposes. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. With a spillway width of 20 feet and a hydraulic height of 12 feet, the structure is designed to manage water flow effectively while ensuring safety and environmental sustainability.

Despite its historical significance and functional purpose for hydroelectricity, Pingree Pond's risk management measures, emergency action plan, and inundation maps have not been fully developed or updated. As climate change continues to impact water resources and extreme weather events become more frequent, proper maintenance and monitoring of this valuable water infrastructure are essential for the safety of the surrounding community and the preservation of the ecosystem.

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 Pingree Pond

Where does the data for Pingree 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.
