Trout Run dam
Trout Run
Trout Run is a crucial water resource infrastructure located in Derry Township, Westmoreland County, Pennsylvania. This local government-owned dam was completed in 1927 with the primary purpose of water supply. With a height of 41 feet and a length of 582 feet, Trout Run has a storage capacity of 166 acre-feet, providing essential water resources to the surrounding area. The dam is state-regulated by the Pennsylvania Department of Environmental Protection, ensuring its compliance with safety and environmental standards.
Trout Run's earth dam type with a buttress core design poses a high hazard potential, although its current condition is assessed as fair. The dam undergoes regular inspections, with the last one conducted in December 2020. Despite its age, Trout Run continues to serve its intended purpose effectively, storing 98 acre-feet of water for normal use. The dam's location in the Baltimore District and its association with the Pennsylvania state agency highlight its significance in water resource management and climate resilience efforts in the region.
For water resource and climate enthusiasts, Trout Run stands as a testament to the importance of well-maintained infrastructure in ensuring water supply security. Its presence serves as a vital component of the local water system, contributing to the sustainability and resilience of the surrounding community. Monitoring Trout Run's condition, regulatory compliance, and emergency preparedness measures are essential aspects of ensuring the continued functionality and safety of this critical water resource infrastructure.

About Trout Run
Where does the data for Trout Run 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 below 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.

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.
