Ladner Pond Dam dam
Ladner Pond Dam
Ladner Pond Dam, also known as Ladner Pond Altermatt Pond, is a privately owned structure located in New Milford, Connecticut. Built in 1965 by the USDA NRCS, this earth dam stands at a height of 18 feet and stretches 350 feet in length, creating a surface area of 15 acres and a storage capacity of 112 acre-feet. The primary purpose of Ladner Pond Dam is for recreation, offering a serene spot for water resource and climate enthusiasts to enjoy.
Situated on the West Aspetuck River Tributary, Ladner Pond Dam is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP) and is subject to state permitting, inspection, and enforcement. With a spillway width of 6 feet and a maximum discharge capacity of 368 cubic feet per second, this dam poses a significant hazard potential, although its condition was assessed as satisfactory during the last inspection in November 2015. The risk assessment for Ladner Pond Dam indicates a moderate risk level, highlighting the importance of ongoing risk management measures to ensure the safety and integrity of this vital water resource structure.
For those interested in the intersection of water resources, climate, and infrastructure, Ladner Pond Dam provides a fascinating case study in dam construction and management. As a key feature in the New Milford landscape, this earth dam serves both recreational and regulatory purposes, underscoring the complexities of balancing human enjoyment with environmental protection. With its rich history, technical specifications, and risk profile, Ladner Pond Dam offers a compelling opportunity for further exploration and analysis by water resource and climate enthusiasts alike.

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 Ladner Pond Dam
Where does the data for Ladner 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 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.
