Summary

Built in 1885, this private dam serves primarily for recreation purposes and stands as a testament to historical engineering with its masonry construction and a height of 21 feet. The dam boasts a normal storage capacity of 295 acre-feet and a maximum storage of 360 acre-feet, providing ample water for the lake's surface area of 47 acres.

Despite its age, Boone Lake's dam is deemed to be in fair condition with a high hazard potential, indicating the importance of regular inspections and maintenance. With a hydraulic height of 16 feet and a spillway width of 72 feet, the dam is capable of handling a maximum discharge of 472 cubic feet per second. Although there are no associated locks, the dam's structural integrity is closely monitored by state regulatory agencies to ensure the safety of the surrounding community. Whether you're a water resource enthusiast or a climate advocate, Boone Lake is a noteworthy example of sustainable water management and a beloved recreational spot in Rhode Island's Washington County.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
