Mitchell Sludge Sedimentation Pond dam
Mitchell Sludge Sedimentation Pond
The Mitchell Sludge Sedimentation Pond, located in Union Township, Pennsylvania, is a privately owned earth dam structure designed for sedimentation purposes along the Monongahela River. Completed in 1982, this 50-foot high dam has a storage capacity of 16 acre-feet and covers a surface area of 0.5 acres. With a drainage area of 0.11 square miles, the pond plays a crucial role in managing sedimentation and water quality in the region.
Managed by the Pennsylvania Department of Environmental Protection, the Mitchell Sludge Sedimentation Pond is considered to have a significant hazard potential, although its condition assessment is deemed satisfactory. Regular inspections are conducted to ensure its structural integrity and operational effectiveness, with the last inspection taking place in November 2017. Despite its private ownership, the dam is regulated and permitted by the state, reflecting a commitment to environmental protection and water resource management.
As a key component of the water infrastructure in Washington County, Pennsylvania, the Mitchell Sludge Sedimentation Pond serves as a vital resource for sediment control and water quality improvement in the region. With its strategic location along the Monongahela River, the dam plays a crucial role in managing sedimentation, highlighting the importance of proactive maintenance and regulatory oversight to ensure its continued effectiveness in safeguarding water resources and mitigating environmental impacts.

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 Mitchell Sludge Sedimentation Pond
Where does the data for Mitchell Sludge Sedimentation 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 Significant 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.
