Summary

Cimini is a state-owned concrete dam located in Williamsport City, Pennsylvania, along the West Branch Susquehanna River. Completed in 1984, this dam primarily serves a recreational purpose, offering opportunities for outdoor activities in the area. With a height of 14.5 feet and a length of 1015 feet, the dam has a storage capacity of 3924 acre-feet and covers a surface area of 677 acres.

Managed by the Pennsylvania Department of Environmental Protection, Anthony J. Cimini is regulated, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. With a low hazard potential and fair condition assessment, this dam has a relatively low risk profile. The last inspection was conducted in June 2019, with an inspection frequency of 5 years to monitor its integrity and performance.

Water resource and climate enthusiasts would appreciate the role of Anthony J. Cimini in providing recreational opportunities and water storage along the West Branch Susquehanna River. The dam's design and construction reflect a commitment to safety and environmental protection, with state agencies actively involved in its regulation and maintenance. As a key infrastructure asset in Lycoming County, Pennsylvania, this dam contributes to the region's water management and outdoor recreation efforts.

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.
