Sedimentation Pond "L-1" dam
Sedimentation Pond "L-1"
Sedimentation Pond "L-1" in Winslow Township, Pennsylvania, is a private earth dam completed in 1992 with a primary purpose of sedimentation. The dam, standing at a height of 15 feet and a length of 270 feet, has a storage capacity of 77 acre-feet and serves as a critical infrastructure for managing water resources in the area. Located on TR Soldier Run in Jefferson County, this pond plays a vital role in controlling sediment and runoff to protect the surrounding environment.
Managed by the Pennsylvania Department of Environmental Protection, Sedimentation Pond "L-1" is state-regulated, inspected, and enforced to ensure its structural integrity and operational efficiency. With a low hazard potential and no current condition rating, the dam continues to fulfill its intended purpose effectively. The last inspection in July 2016 deemed it safe, with a five-year inspection frequency to monitor any changes in its performance. Although not rated for condition assessment, the dam's presence contributes to the overall water management strategy in the region.
The location of Sedimentation Pond "L-1" near Pittsburgh District provides essential water storage and sediment control measures for the local community. With a focus on sedimentation and a capacity to hold 77 acre-feet of water, this earth dam stands as a reliable resource for maintaining water quality and quantity in the area. As climate change impacts water resources, the proper management of structures like Sedimentation Pond "L-1" becomes increasingly important to ensure sustainable water practices for the future.

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 Sedimentation Pond "L-1"
Where does the data for Sedimentation Pond "L-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 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.
