Oak Tree dam
Oak Tree
Oak Tree is a private-owned dam located in Shenango Township, Mercer County, Pennsylvania, along the Oak Branch stream. Built in 1967, this earth dam stands at a height of 24 feet and stretches 245 feet in length, with a storage capacity of 68 acre-feet. The primary purpose of Oak Tree Dam is for recreation, offering a surface area of 4.3 acres within a drainage area of 1.27 square miles.
Managed by the Pennsylvania Department of Environmental Protection, Oak Tree Dam is state-regulated and undergoes regular inspections, with the last inspection conducted in July 2019. Classified with a low hazard potential and a condition assessment of "Not Rated," this structure has not been evaluated for its emergency action plan (EAP) preparedness or risk management measures. Despite its relatively low risk, Oak Tree Dam remains an important feature for water resource and climate enthusiasts seeking recreational opportunities in the area.
With its serene setting and recreational offerings, Oak Tree Dam serves as a valuable asset within the community, providing both leisure activities and crucial water resource management functions. As enthusiasts explore the dam's surroundings, they can appreciate its historical significance and the role it plays in enhancing the local environment. Its regulated status and regular inspections ensure its continued safety and functionality, making it a noteworthy site for those interested in water resource management and climate-related activities.

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 Oak Tree
Where does the data for Oak Tree 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 Low 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.
