Spruce Run Reservoir dam
Spruce Run Reservoir
Spruce Run Reservoir, located in White Deer Township, Pennsylvania, is a vital water supply reservoir with a capacity of 1,860 acre-feet and a surface area of 64 acres. The reservoir was completed in 1957 and primarily serves as a source of water for the surrounding area. With a drainage area of 13.5 square miles, Spruce Run Reservoir plays a crucial role in providing water for various purposes, including domestic, agricultural, and industrial use.
This Earth dam structure stands at a height of 46 feet and spans a length of 4,900 feet, with a core type of Buttress. The reservoir underwent structural modifications in 2005 to ensure its continued functionality and safety. Despite being rated as having a high hazard potential, the dam is currently assessed to be in fair condition. Regular inspections are conducted, with the last inspection taking place in June 2020, to monitor the dam's integrity and address any maintenance needs promptly.
Managed by a private entity and regulated by the Pennsylvania Department of Environmental Protection, Spruce Run Reservoir is a critical water resource in Union County, Pennsylvania. Its strategic location and significant storage capacity make it an essential component of the region's water infrastructure, ensuring a reliable supply of water for the community while also contributing to the area's environmental sustainability efforts.

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 Spruce Run Reservoir
Where does the data for Spruce Run Reservoir 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.
