Ridgley Pond Dam dam
Ridgley Pond Dam
Ridgley Pond Dam, located in Templeton, Massachusetts, is a private-owned structure that serves primarily for recreation purposes. This Earth dam, with a height of 12 feet and a hydraulic height of 11.5 feet, impounds the waters of the Otter River. With a normal storage capacity of 33 acre-feet and a surface area of 6.53 acres, the dam is regulated by the Department of Conservation and Recreation in Massachusetts.
The dam's hazard potential is classified as significant, with a satisfactory condition assessment as of October 2016. Despite its moderate risk level, the dam's emergency action plan status and risk management measures are currently unlisted. As a popular recreation spot, Ridgley Pond Dam presents an important water resource for the local community, offering opportunities for fishing, boating, and other outdoor activities.
While the dam has not been modified in recent years, regular inspections are conducted to ensure its structural integrity and safety. The dam's location in Worcester County, Massachusetts, makes it a key feature in the region's water resource management. As climate enthusiasts and water resource advocates, it is imperative to monitor and support the maintenance and upkeep of structures like Ridgley Pond Dam to mitigate potential risks and preserve the health of our waterways in the face of changing environmental conditions.
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 Ridgley Pond Dam
Where does the data for Ridgley 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.
