Brunner Island Ash Basin No 6 dam
Brunner Island Ash Basin No 6
Brunner Island Ash Basin No 6 is a significant earth dam located in East Manchester Township, Pennsylvania. Completed in 1979, this dam stands at a height of 39 feet and has a length of 8300 feet, providing storage capacity of 2599 acre-feet. Situated within the watershed of the Susquehanna River, this dam is regulated by the Pennsylvania Department of Environmental Protection and undergoes regular inspections to ensure its structural integrity.
The primary purpose of Brunner Island Ash Basin No 6 is classified as 'Other', with a core type of Buttress and an unspecified foundation type. Despite being in satisfactory condition, the dam is designated with a significant hazard potential, calling for a thorough risk assessment and management strategy. In 2007, mechanical modifications were made to enhance its operational efficiency. With its location in a crucial water resource area, this dam plays a vital role in managing water flow and storage within the region.
Owned and maintained by a private entity, Brunner Island Ash Basin No 6 serves as a critical infrastructure in York, Pennsylvania. With its strategic position and storage capacity, this dam contributes to the overall water resource management in the Susquehanna River watershed. Climate and water enthusiasts would find interest in the complexities of managing and maintaining such vital structures to ensure the sustainability and resilience of water resources in the face of changing 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 Brunner Island Ash Basin No 6
Where does the data for Brunner Island Ash Basin No 6 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 Significant 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.
