Long Run Reservoir No 1 dam
Long Run Reservoir No 1
Long Run Reservoir No 1, located in Franklin Township, Carbon County, Pennsylvania, is a crucial water supply reservoir managed by the local government. Completed in 1885, this Earth-type dam stands at a height of 26 feet and spans a length of 290 feet, with a storage capacity of 73 acre-feet. The reservoir serves the primary purpose of water supply, with a normal storage capacity of 61 acre-feet and a surface area of 3 acres.
Despite its age, Long Run Reservoir No 1 is regulated and inspected by the Pennsylvania Department of Environmental Protection, ensuring its structural integrity and safe operation. The dam has a high hazard potential but is currently assessed to be in fair condition. The last inspection was conducted in June 2020, with a frequency of once per year. While the reservoir does not have an Emergency Action Plan (EAP) in place, it meets regulatory guidelines and has emergency contacts updated as necessary.
Water resource and climate enthusiasts will appreciate the historical significance and engineering feat of Long Run Reservoir No 1, as well as its ongoing importance in providing water supply to the local community. The reservoir's location on the Long Run stream, within the Philadelphia District of the US Army Corps of Engineers, highlights the interconnectedness of water resources management in the region. With a commitment to regular inspections and regulatory oversight, Long Run Reservoir No 1 continues to play a vital role in ensuring reliable water supply and public safety in Carbon County.

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 Long Run Reservoir No 1
Where does the data for Long Run Reservoir No 1 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.
