Summary

Managed by the local government and regulated by the Department of Natural Resources, this dam stands at a height of 33 feet and has a storage capacity of 93.2 million gallons. The dam's primary purpose is to ensure a stable water supply for the area, with normal storage levels at 64.4 million gallons.

Located in Greenshills, Ohio, this dam plays a crucial role in water resource management for the region. With a drainage area of 0.4 square miles and a surface area of 4.7 acres, the dam has a maximum discharge capacity of 465 cubic feet per second. Despite its significant hazard potential, the dam is assessed to be in satisfactory condition as of the last inspection in April 2016. Emergency action plans are in place, demonstrating preparedness for any potential risks associated with the dam.

For water resource and climate enthusiasts, the Winton Woods Golf Course Lake "E" Dam serves as a focal point for understanding the intersection of infrastructure, water supply, and environmental stewardship. As a vital component of the local water management system, this dam exemplifies the importance of sustainable practices in safeguarding precious water resources for future generations. With a history of successful operation and maintenance, the dam stands as a testament to effective dam engineering and regulatory oversight in ensuring the resilience of water infrastructure in the face of changing climatic 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.
