Holley Lane Pond Reservoir Report
Nearby: Sylvester Pond Harris Pond
Last Updated: March 17, 2026
Holley Lane Pond is a privately owned water resource located in Providence, Rhode Island, with a high hazard potential and poor condition assessment.
Summary
This pond is regulated by the state and undergoes regular inspections, enforcement, and permitting processes. It is situated near Iron Rock Brook and has a dam height of 8 feet, although other details such as dam volume, storage capacity, and completion year are unknown.
Despite its lack of specific information on purposes or design, Holley Lane Pond remains a focal point for water resource and climate enthusiasts in the region. The pond's association with the New England District of the US Army Corps of Engineers adds to its significance, although it does not fall under federal ownership or funding. With a history dating back to an inspection in 2013, efforts to ensure the safety and integrity of Holley Lane Pond are crucial for both the local community and environmental sustainability in the area.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
