Bonnice dam
Bonnice
Bonnice, a privately-owned dam located in Jessup Township, Pennsylvania, stands as both a recreational asset and a significant water resource in the region. 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
- 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.
- 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.
- 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.
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, environmental 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.

About Bonnice
Where does the data for Bonnice come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
