Reynoldsville Storage #5 dam
Reynoldsville Storage #5
Reynoldsville Storage #5, located in Winslow Township, Pennsylvania, is a crucial earth dam built in 1901 for water supply purposes. With a height of 26 feet and a length of 240 feet, the dam has a storage capacity of 34 acre-feet, serving the surrounding area with a normal storage of 21 acre-feet. The structure overlooks the picturesque Pitchpine Run, contributing to the local Jefferson County's water resource management.
Despite its historical significance, Reynoldsville Storage #5 is facing challenges with a high hazard potential and poor condition assessment. The dam was last inspected in October 2020, with a frequency of one inspection per year. In 2007, structural modifications were made to enhance the dam's safety and reliability, but ongoing maintenance and potential risk management measures are needed to ensure the community's safety and water supply sustainability.
With the Pennsylvania Department of Environmental Protection as the state regulatory agency overseeing its operations, Reynoldsville Storage #5 serves as a critical infrastructure in the region. The dam's significance lies not only in its water supply functions but also in the need for continued monitoring, maintenance, and possibly, risk mitigation strategies to adapt to changing climate conditions and ensure the resilience of this essential water resource facility.

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 Reynoldsville Storage #5
Where does the data for Reynoldsville Storage #5 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.
