Aldon Mill Pond Dam Dam
Aldon Mill Pond Dam
Aldon Mill Pond Dam, also known as Tankerhoosen Pond, is a picturesque masonry dam located in Talcotville, Connecticut. Built in 1920, this dam serves primarily for recreational purposes and stands at 25 feet high with a length of 95 feet. With a storage capacity of 87 acre-feet and a drainage area of 12.6 square miles, it contributes to the beauty and ecosystem of the Tankerhoosen River.
Despite its historic significance and recreational value, Aldon Mill Pond Dam has been flagged with a significant hazard potential and poor condition assessment. The last inspection in 2015 revealed areas of concern, prompting the need for further evaluation and potential maintenance or rehabilitation. The dam's spillway, an uncontrolled type with a width of 72 feet, poses potential risks that must be addressed to ensure the safety of surrounding communities and the environment.
As enthusiasts of water resources and climate, it is crucial to monitor and address the condition of Aldon Mill Pond Dam to mitigate potential hazards and preserve its role in recreation and water management. With a moderate risk assessment rating and a history dating back to the early 20th century, this dam serves as a reminder of the delicate balance between human development and environmental stewardship in our changing climate.

About Aldon Mill Pond Dam
Where does the data for Aldon Mill Pond Dam 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 Significant 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.
