Summary

Built in 1905, this gravity dam stands at 10 feet tall and has a structural height of 14 feet, with a storage capacity of 60 acre-feet. With a surface area of 10 acres and a drainage area of 9 square miles, Round Top Pond plays a crucial role in providing recreational opportunities while also serving as a habitat for various wildlife species.

Despite its age, Round Top Pond has a low hazard potential but is currently in poor condition, as assessed in October 2017. The dam has a normal storage capacity of 50 acre-feet and a maximum discharge rate of 2076 cubic feet per second. With a spillway width of 58 feet, the dam is equipped to handle excess water flow during heavy rainfall events. Although the dam has not been modified in recent years, regular inspections are conducted to ensure its structural integrity and the safety of surrounding areas.

As a significant water resource in Providence County, Round Top Pond contributes to the overall health of Roundtop Brook and provides valuable habitat for various aquatic and terrestrial species. While the dam's condition may be a concern, ongoing inspections and potential maintenance efforts aim to preserve this important ecosystem and recreational area for future generations to enjoy.

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.
