Summary

Completed in 1984, this structure stands at a height of 41 feet and spans 660 feet in length, providing a critical storage capacity of 112 acre-feet. The dam serves as a key component of flood risk reduction efforts in the region, with a primary purpose of safeguarding the local community from potential inundation.

Managed by the local government, Conneautville (Pa-112) is regulated by the Pennsylvania Department of Environmental Protection, ensuring that the dam meets state standards for safety and operation. Despite being assessed as in fair condition, it has a high hazard potential, underscoring the importance of regular inspections and maintenance. With a capacity to store 81 acre-feet of water under normal conditions, this dam plays a crucial role in protecting the surrounding area from the impacts of extreme weather events and ensuring the resilience of the local water resources.

As a key flood risk reduction infrastructure in the Pittsburgh District, Conneautville (Pa-112) is a testament to the collaborative efforts of various agencies and designers. With its strategic location in Conneautville Borough and the support of the Natural Resources Conservation Service, this dam exemplifies the importance of proactive measures in water resource management and climate resilience. Its role in safeguarding the community and surrounding areas from potential flooding highlights the critical intersection between infrastructure development, environmental protection, and public safety in the face of changing climate conditions.

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. 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

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, 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.
