About this dam

Treated Water Pond

Treated Water Pond, located in Fallowfield Township, Pennsylvania, is a privately owned water resource regulated by the Pennsylvania Department of Environmental Protection. This earth dam structure, completed in 1966, serves a primary purpose of "Other" and has a storage capacity of 877 acre-feet. With a dam height of 58.8 feet and a length of 3400 feet, the pond covers a surface area of 25 acres and drains an area of 0.06 square miles.

The dam's hazard potential is rated as "High", but its condition assessment is deemed "Satisfactory". It is regularly inspected by the Mine Safety and Health Administration, with the last inspection taking place in April 2020. Despite being non-federally owned, Treated Water Pond falls under state jurisdiction and is subject to permitting, inspection, and enforcement by the Pennsylvania Department of Environmental Protection. Its location near Sawmill Creek in Washington County, Pennsylvania highlights its importance in managing water resources in the region.

For water resource and climate enthusiasts, Treated Water Pond represents a significant infrastructure that plays a crucial role in water management and regulation. Its storage capacity, structural characteristics, and regulatory oversight make it a key component in ensuring water quality and safety in the area. As climate change continues to impact water resources, understanding and monitoring structures like Treated Water Pond are essential for sustainable water management practices in 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.

FAQ

About Treated Water Pond

Where does the data for Treated Water Pond 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.
