Caucomgomoc Lake dam
Caucomgomoc Lake
Caucomgomoc Lake, located in Chesuncook, Maine, is a picturesque body of water fed by the Caucomgomoc Stream. This hydroelectric reservoir was completed in 1981 and serves multiple purposes including fish and wildlife pond, flood risk reduction, navigation, recreation, and water supply. With a surface area of 5728 acres and a drainage area of 177.5 square miles, the lake has a maximum discharge capacity of 14,750 cubic feet per second.
The dam at Caucomgomoc Lake stands at a height of 16 feet and has a length of 2584 feet, with a storage capacity of 42,516 acre-feet. The spillway is of the controlled type with a width of 148 feet. Although the hazard potential is considered low, the risk assessment for the area is rated as very high. The Federal Energy Regulatory Commission oversees the regulation and inspection of the dam, ensuring its safe operation for the surrounding community and environment.
For water resource and climate enthusiasts, Caucomgomoc Lake offers an intriguing glimpse into the intricate balance between human infrastructure and natural ecosystems. The lake's role in supporting various activities while managing flood risks and providing hydroelectric power highlights the importance of sustainable water resource management in the face of changing climate conditions. With its scenic beauty and functional design, Caucomgomoc Lake stands as a testament to the ingenuity and responsibility required to harness the power of water for the benefit of all.

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 Caucomgomoc Lake
Where does the data for Caucomgomoc Lake 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.
