Mill Pond Lpp Dam
Mill Pond Lpp
Mill Pond Lpp in Maine is a privately owned concrete dam constructed in 1917 for flood risk reduction along the Mattanawcook Stream. With a dam height of 18 feet and a storage capacity of 132 acre-feet, this structure serves multiple purposes including fire protection, stock, and small fish pond management. The dam's low hazard potential and not rated condition assessment suggest a stable and well-maintained infrastructure.
Located in Penobscot County, this dam has a hydraulic height of 16 feet and a spillway width of 112 feet, ensuring efficient water management during peak discharge events. Although last inspected in 2007, with inspection frequency of 12 years, Mill Pond Lpp remains a crucial asset for water resource management in the region. With state regulation and enforcement in place, the dam continues to play a vital role in protecting the local community from flooding and ensuring water availability for various needs.
As climate change impacts intensify, structures like Mill Pond Lpp highlight the importance of resilient infrastructure for adapting to changing hydrological patterns. With its historical significance and multifaceted purposes, this dam symbolizes the intersection of water resource management, climate resilience, and community safety. As water resource and climate enthusiasts, understanding and advocating for the upkeep and modernization of such critical infrastructure is essential for ensuring sustainable water management in the face of a changing climate.

About Mill Pond Lpp
Where does the data for Mill Pond Lpp 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 below 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.

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.
