Ambrose Mine dam
Ambrose Mine
Ambrose Mine is a privately owned water resource structure located in East Franklin Township, Armstrong County, Pennsylvania. It is regulated by the Pennsylvania Department of Environmental Protection and falls under the jurisdiction of the state. The dam, classified as an Earth type with a buttress core, stands at a height of 26 feet and has a length of 260 feet, providing a storage capacity of 30 acre-feet.
The primary purpose of Ambrose Mine is for recreation and other unspecified uses, with a low hazard potential and a condition assessment that is currently not rated. The last inspection of the dam took place in November 2017, with a scheduled inspection frequency of 5 years. Despite not being under the jurisdiction of the US Army Corps of Engineers, Ambrose Mine serves as an important water resource structure for the local community, contributing to the management of the Allegheny River watershed.
Enthusiasts of water resources and climate will find Ambrose Mine to be an intriguing example of a privately owned dam in Pennsylvania. Its location along the Allegheny River, its design as an Earth type dam, and its regulated status by the state make it a noteworthy structure in the region. With a focus on recreation and other purposes, Ambrose Mine plays a vital role in water storage and management, showcasing the intersection of human intervention and natural resources in the area.
Dam data reference
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 Ambrose Mine
Where does the data for Ambrose Mine 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.
