Evans City Waterworks No 1 dam
Evans City Waterworks No 1
Evans City Waterworks No 1, located in Jackson Township, Butler County, Pennsylvania, is a vital piece of infrastructure designed for water supply purposes. This dam, completed in 1954, stands at a height of 37.5 feet and spans 400 feet in length. With a storage capacity of 390 acre-feet, it serves as an essential resource for the surrounding community, particularly during times of water scarcity.
Managed by the Pennsylvania Department of Environmental Protection, the Evans City Waterworks No 1 dam is subject to state regulation, inspection, and enforcement to ensure its structural integrity and operational efficiency. Despite being classified as having a high hazard potential, the dam is currently assessed as being in fair condition, highlighting the importance of ongoing maintenance and monitoring efforts. With a surface area of 18 acres and a drainage area of 3.5 square miles, this dam plays a crucial role in managing water resources in the region.
As climate change continues to impact water availability and quality, infrastructure like Evans City Waterworks No 1 will be increasingly important in securing a reliable water supply for communities in Pennsylvania. The data on this dam's specifications and regulatory oversight provide valuable insights for water resource and climate enthusiasts interested in understanding the intersection of infrastructure, water management, and climate resilience.
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 Evans City Waterworks No 1
Where does the data for Evans City Waterworks No 1 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.
