About this dam

Negro Pond

Negro Pond, located in Windham Township, Pennsylvania, is a privately owned recreational water resource built in 1919. This earth dam structure stands at a height of 7 feet and spans 125 feet in length, with a storage capacity of 750 acre-feet. The pond covers an area of 81 acres and is fed by the Little Mehoopany Creek, making it a picturesque destination for water and climate enthusiasts.

Despite its historical significance, Negro Pond has been classified as having a high hazard potential and a poor condition assessment, indicating the need for maintenance and potential improvements. The Pennsylvania Department of Environmental Protection regulates the pond, overseeing its inspection, enforcement, and permitting processes. With a moderate risk assessment of 3, there is room for further risk management measures to ensure the safety and sustainability of this valuable water resource.

As a key recreational site in Wyoming County, Pennsylvania, Negro Pond offers opportunities for outdoor activities and serves as a habitat for diverse flora and fauna. Its presence along the Little Mehoopany Creek contributes to the local ecosystem and water network, making it a vital component for both residents and visitors to enjoy and appreciate. Efforts to enhance the pond's condition and reduce potential risks will help preserve its ecological value and ensure its continued contribution to the surrounding environment.

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 Negro Pond

Where does the data for Negro 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.
