Littleville Dam - Saddle Dike dam
Littleville Dam - Saddle Dike
Littleville Dam - Saddle Dike, located in Hampshire, Massachusetts, along the Westfield River, is a gravity dam with a height of 46 feet and a length of 935 feet. Completed in 1965 by the US Army Corps of Engineers, its primary purpose is flood risk reduction. The dam, managed by USACE, has a high hazard potential and a frequency of inspection every 5 years.
The dam's risk management measures include continual monitoring, prioritizing activities to reduce risks, and engaging with emergency managers and the public to raise awareness and readiness for dam-related emergencies. USACE works closely with local officials to develop emergency and evacuation plans, regularly updates the emergency action plan, and conducts maintenance and repairs as needed to ensure the dam's proper functioning. Despite efforts to mitigate risks, the dam does not eliminate all flood risk, and severe weather events can lead to dam releases or structural issues.
Overall, Littleville Dam - Saddle Dike serves as a crucial asset in managing flood risk in the area. With ongoing risk management measures and collaboration with local authorities, the dam plays a vital role in protecting the surrounding communities from potential flooding events. As the US Army Corps of Engineers continues to monitor and maintain the dam, efforts are focused on enhancing preparedness and response capabilities to ensure the safety and resilience of the region in the face of water resource and climate challenges.
Dam data reference
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 Littleville Dam - Saddle Dike
Where does the data for Littleville Dam - Saddle Dike 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 High 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.
