Langworthy Pond dam
Langworthy Pond
Langworthy Pond, located in Hopkinton, Rhode Island, is a privately owned dam that serves as an essential water resource in the area. This earth dam, standing at a height of 9 feet with a hydraulic height of 8 feet, plays a crucial role in regulating the flow of Brushy Brook-tributary. With a storage capacity of 3 acre-feet, the pond covers an area of 1 acre and has a spillway width of 14 feet.
Despite being classified as having a significant hazard potential, Langworthy Pond is currently in fair condition, as assessed in October 2017. The dam has been inspected regularly every 5 years, with the last inspection conducted in November 2011. While no major modifications or risk management measures have been reported, the pond's emergency action plan status and adherence to guidelines remain unclear. With its importance to the local water supply and environmental ecosystem, Langworthy Pond stands as a critical infrastructure requiring continuous monitoring and maintenance to ensure its safety and functionality for the community.
Managed by a private owner, Langworthy Pond's presence highlights the intersection of water resource management and climate resilience in Rhode Island. As a state-regulated and permitted structure, the pond represents a key element in the region's water infrastructure, providing both storage capacity and flood control measures. With the potential for significant hazard, continued efforts in risk assessment, emergency preparedness, and maintenance are essential to safeguarding the pond and its surrounding areas from potential disasters.

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 Langworthy Pond
Where does the data for Langworthy Pond 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.
