Summary

The dam, located on TR Brush Creek, serves the primary purpose of flood risk reduction and stands at a height of 17.5 feet with a storage capacity of 9.7 acre-feet. With a drainage area of 1.81 square miles, Manor Creek Farms plays a crucial role in mitigating flood risks in the Butler County region.

Despite its significant hazard potential, Manor Creek Farms has not been rated for its condition assessment as of the last inspection in August 2018. The dam, classified as an Earth type structure with a Buttress core, has a length of 600 feet and has not undergone any modifications in recent years. While the risk management measures and emergency action plans for the dam remain undisclosed, its existence underscores the importance of maintaining and monitoring water resources in the face of changing climate patterns and increasing flood risks.

For water resource and climate enthusiasts, Manor Creek Farms presents a fascinating case study in the management of flood risk through private ownership and state regulation. The dam's location in the Pittsburgh District highlights the interconnectedness of water infrastructure and environmental protection efforts in safeguarding communities from the impacts of extreme weather events. As discussions around climate resilience and water resource management continue to gain prominence, the insights from Manor Creek Farms can inform broader conversations on sustainable infrastructure development and disaster preparedness in a changing climate.

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.
