Hughes Hollow Slurry Impoundment dam
Hughes Hollow Slurry Impoundment
Hughes Hollow Slurry Impoundment in Greene, Pennsylvania, is a privately owned structure regulated by the Pennsylvania Department of Environmental Protection. Located in Wayne Township, this Earth-type dam stands at a height of 245 feet and stretches 1350 feet in length, with a storage capacity of 3905 acre-feet. Despite its significant size, the dam is rated as having a high hazard potential but maintains a satisfactory condition based on the last inspection in March 2021.
The impoundment, situated along Hughes Run, serves a primary purpose that is classified as "Other," with a normal storage capacity of 3548 acre-feet and a surface area of 50 acres. While the dam lacks specific details on its spillway type and spillway width, it is equipped for inspections and enforcement by the state regulatory agency. The risk assessment and emergency action plan status for the site remain unclear, underscoring the need for further evaluation and preparedness in the event of an emergency related to the dam's operation.
For water resource and climate enthusiasts, the Hughes Hollow Slurry Impoundment represents a key infrastructure in Pennsylvania that requires ongoing monitoring and maintenance to ensure public safety and environmental protection. With its substantial storage capacity and high hazard potential, stakeholders must stay vigilant in addressing any potential risks associated with this dam to mitigate the impact on downstream areas and the surrounding ecosystem.

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 Hughes Hollow Slurry Impoundment
Where does the data for Hughes Hollow Slurry Impoundment 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 High 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.
