Lydall Pond #1 Dam Dam
Lydall Pond #1 Dam
Lydall Pond #1 Dam, also known as Salters Pond, is a concrete structure located in Manchester, Connecticut, built in 1898 for recreational purposes. With a height of 12 feet and a length of 150 feet, the dam has a storage capacity of 64 acre-feet and covers a surface area of 9.2 acres. The dam is regulated by the state of Connecticut's Department of Energy and Environmental Protection (DEEP) and has a significant hazard potential.
The dam, situated on Lydall Brook, is designed with an uncontrolled spillway that is 75 feet wide, capable of discharging a maximum of 1200 cubic feet per second. Although it has not been rated for its condition, the dam has undergone inspections with a frequency of 7 years, with the last assessment conducted in October 2014. The risk assessment for the dam is moderate (3), suggesting a need for ongoing monitoring and management measures to ensure its safety and stability.
Enthusiasts of water resources and climate will find Lydall Pond #1 Dam a fascinating structure that not only provides recreational opportunities but also presents challenges in terms of risk management and maintenance. With its historical significance and strategic location in Hartford County, Connecticut, the dam serves as a vital component of the local ecosystem and water management infrastructure, highlighting the importance of sustainable practices in safeguarding our natural resources.

About Lydall Pond #1 Dam
Where does the data for Lydall Pond #1 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.
