Harrisville Pond dam
Harrisville Pond
Harrisville Pond, located in Burrillville, Rhode Island, is a picturesque body of water that serves as a popular recreational spot for locals and visitors alike. The pond, with a surface area of 18 acres and a maximum storage capacity of 100 acre-feet, was completed in 1854 and has a primary purpose of recreation. Managed by local government authorities, the dam at Harrisville Pond is a Rockfill type with a structural height of 22 feet, providing essential water storage and flood control benefits for the surrounding area.
With a drainage area of 43 square miles and a maximum discharge capacity of 3200 cubic feet per second, Harrisville Pond plays a crucial role in managing water flow along the Pascoag River. The dam, standing at 19 feet tall with a hydraulic height of 17 feet, has been assessed to be in fair condition with a high hazard potential. Regular inspections are conducted to ensure the dam's integrity and safety, with the last assessment taking place in October 2017.
Despite its age, Harrisville Pond continues to be a valuable resource for the community, offering opportunities for fishing, boating, and other recreational activities. Its historic significance, combined with its practical function in water management, makes it a focal point for water resource and climate enthusiasts interested in the intersection of human development and natural ecosystems.
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 Harrisville Pond
Where does the data for Harrisville 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 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.
