Lake Saxony dam
Lake Saxony
Lake Saxony, located in Jefferson Township, Butler County, Pennsylvania, is a private irrigation reservoir built in 1958 on Sarver Run. The dam, primarily used for irrigation purposes, stands at a height of 25.7 feet and has a storage capacity of 320 acre-feet. With a surface area of 9.6 acres and a drainage area of 1.1 square miles, the reservoir provides essential water resources for agricultural needs in the region.
Managed by the Pennsylvania Department of Environmental Protection, Lake Saxony is regulated, inspected, and enforced to ensure its structural integrity and safety. Despite being classified as having a high hazard potential, the dam is in fair condition as of the last inspection in September 2020. The reservoir also offers recreational opportunities in addition to its primary irrigation function, making it a valuable asset for the community.
Over the years, Lake Saxony has undergone modifications, most notably in 2005 for hydraulic improvements. With its significant storage capacity and strategic location, the reservoir plays a crucial role in water management and conservation efforts in the area. Climate and water resource enthusiasts can appreciate the unique characteristics and importance of Lake Saxony in sustaining both agricultural and recreational activities while ensuring water security for the region.

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 Lake Saxony
Where does the data for Lake Saxony 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.
