North Fork dam
North Fork
North Fork, a local government-owned dam in Somerset, Pennsylvania, plays a crucial role in water supply management. Completed in 1932, this Earth dam stands at a height of 105 feet and spans 900 feet, with a storage capacity of 4316 acre-feet. The dam's primary purpose is water supply, serving to regulate the flow of the North Fork Bens Creek.
Despite its essential function, North Fork poses a high hazard potential due to its poor condition assessment, prompting concerns for risk management. With a very high risk rating, this dam's safety and stability are critical issues that require attention and strategic measures to mitigate potential hazards. The Pennsylvania Department of Environmental Protection oversees state regulations, permitting, inspection, and enforcement for this dam, emphasizing the importance of ongoing monitoring and maintenance to ensure public safety and water resource sustainability.
As a key infrastructure for water resource management in the region, North Fork serves as a critical asset for Conemaugh Township. However, with its high hazard potential and poor condition, there is an urgent need for risk assessment, management measures, and maintenance to safeguard the dam's integrity and the surrounding community. Collaboration between local authorities, regulatory agencies, and stakeholders is essential to address the challenges posed by this vital water supply structure and ensure its long-term resilience in the face of evolving climate and environmental conditions.

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 North Fork
Where does the data for North Fork 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.
