York Haven East Channel Dam dam
York Haven East Channel Dam
The York Haven East Channel Dam in Pennsylvania, completed in 1918, stands as a concrete gravity dam on the Susquehanna River, serving multiple purposes such as hydroelectric power generation, recreation, and water supply. With a height of 8 feet and a length of 950 feet, the dam boasts a storage capacity of 7800 acre-feet and a maximum discharge of 21300 cubic feet per second. Managed by the Federal Energy Regulatory Commission, the dam is crucial for enhancing water resource management and climate resilience in the region.
Despite being classified as having a low hazard potential, the dam presents moderate risks that require careful monitoring and management. Given its strategic location and significant impact on the surrounding area, the York Haven East Channel Dam plays a vital role in ensuring water security and supporting sustainable development. With its historical significance and ongoing contributions to the local community, the dam serves as a testament to the importance of effective dam infrastructure in addressing the challenges of a changing climate.
As a key component of the water infrastructure in Dauphin County, Pennsylvania, the York Haven East Channel Dam underscores the critical need for proactive risk assessment and management in safeguarding water resources and mitigating climate-related hazards. With its blend of historic heritage and modern functionality, the dam continues to play a pivotal role in promoting environmental sustainability and enhancing the resilience of the region in the face of evolving climate dynamics.

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 York Haven East Channel Dam
Where does the data for York Haven East Channel Dam 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 Low 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.
