Colvin Sedimentation Pond dam
Colvin Sedimentation Pond
Colvin Sedimentation Pond, located in Monongahela Township, Greene County, Pennsylvania, is a privately owned Earth dam constructed in 1980 to manage sedimentation in TR Whiteley Creek. With a height of 43 feet and a length of 300 feet, the pond has a storage capacity of 85 acre-feet, providing essential water resource management in the area. The dam's primary purpose is categorized as 'Other', serving as a crucial structure for sediment control and water quality maintenance.
Managed by the Pennsylvania Department of Environmental Protection, Colvin Sedimentation Pond is regulated, inspected, and enforced by state authorities to ensure its structural integrity and hazard mitigation. The dam's condition assessment is reported as 'Satisfactory', with a significant hazard potential, highlighting the importance of regular inspections and maintenance. Despite its satisfactory condition, the dam's emergency action plan status, inundation maps, and risk assessment information remain unspecified, indicating a potential area for improvement in emergency preparedness and risk management measures.
With its strategic location and significant role in sediment control and water management, Colvin Sedimentation Pond stands as a vital infrastructure in Greene County, Pennsylvania. As a key component of water resource management in the region, the dam's condition and emergency preparedness are crucial aspects that require continuous monitoring and updating to ensure the safety and efficiency of its operations for both water resource and climate enthusiasts alike.

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 Colvin Sedimentation Pond
Where does the data for Colvin 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.
