Summary
Woolpert Co. and completed in 1966. This earth dam stands at a height of 28.7 feet and spans a length of 275 feet, creating a reservoir with a normal storage capacity of 23 acre-feet for recreational purposes. The dam is regulated by the Ohio Department of Natural Resources and has a high hazard potential, although its condition was assessed as satisfactory during the last inspection in March 2016.
With a drainage area of 0.09 square miles and a maximum discharge capacity of 842 cubic feet per second, Lake Marinole Dam serves as a vital component in the management of water resources in the region. The dam is situated on a tributary to Holes Creek, offering not only recreational opportunities but also contributing to flood control and downstream water quality. Despite its critical role, the dam's emergency action plan and risk assessment measures were not available at the time of data collection in 2021, highlighting the importance of ongoing monitoring and maintenance to ensure public safety and environmental protection.
Lake Marinole Dam, nestled in Montgomery County, Ohio, under the jurisdiction of the Louisville District, is a key feature in the local landscape. As climate change continues to impact water resources, the effective management of dams like Lake Marinole becomes increasingly important in safeguarding communities and ecosystems. With its blend of functionality for recreation and water management, Lake Marinole Dam stands as a testament to the integration of human infrastructure with natural systems, showcasing the intricate balance needed to navigate the challenges of a changing climate.

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.
