Summary
This Earth-type dam, with a height of 39.5 feet and a length of 360 feet, was completed in 1988 and has a storage capacity of 374.5 acre-feet. The pond covers a surface area of 12 acres and has a drainage area of 2.7 square miles, making it a vital component of water resource management in Allegheny County.
Managed by the Pennsylvania Department of Environmental Protection, the Midfield Sedimentation Pond is state-regulated and undergoes regular inspections to ensure its structural integrity and effectiveness in flood control. Despite its high hazard potential, the dam is currently in satisfactory condition, with the last inspection conducted in November 2020. As a local government-owned facility, it plays a key role in protecting the surrounding area from potential flooding events and serves as a vital asset in the region's water resource management strategy.
With its primary purpose focused on flood risk reduction, the Midfield Sedimentation Pond stands as a testament to the collaborative efforts between local and state agencies in mitigating the impact of extreme weather events on the community. As climate change continues to influence precipitation patterns and water availability, the importance of well-maintained infrastructure like this sedimentation pond cannot be overstated. As a critical component of the region's water resource infrastructure, the Midfield Sedimentation Pond serves as a vital tool in adapting to the challenges posed by a changing climate and protecting the local community from the threat of flooding.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
