Summary
Completed in 1969, this earth dam with a height of 18 feet and a length of 550 feet, impounds the TR East Branch Wyalusing Creek, providing a storage capacity of 67 acre-feet and covering a surface area of 12 acres. Despite its purpose primarily for recreation, its strategic location and state-regulated status underline its importance in water management and conservation efforts.
Managed by the Pennsylvania Department of Environmental Protection, Bonnice is subject to regular inspections, with the last one conducted in August 2020. With a hazard potential classified as significant, the dam's condition remains unrated, highlighting the need for ongoing monitoring and maintenance to ensure its safety and functionality. While the dam's Emergency Action Plan status and risk assessment details are currently unspecified, the structure's critical role in water management underscores the importance of proactive risk management and emergency preparedness measures.
As part of the larger water infrastructure in the Susquehanna region and under the jurisdiction of both state and federal agencies, Bonnice serves as a vital component in water resource management and climate resilience strategies. Its presence along the TR East Branch Wyalusing Creek not only offers recreational opportunities but also underscores the interconnectedness of water resources, infrastructure, and environmental stewardship in safeguarding communities and ecosystems against the impacts of climate change and water-related hazards.

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.
