Summary

With a height of 51.9 feet and a length of 470 feet, the dam provides a storage capacity of 144 acre-feet and a surface area of 8.5 acres. It is regulated by the Ohio Department of Natural Resources and has a significant hazard potential, although its condition is assessed as fair.

The dam, situated on a tributary to Newman Run, serves as a popular recreation spot for locals and visitors, offering opportunities for fishing, boating, and other water activities. Its state-regulated status ensures that it undergoes regular inspections, with the last assessment conducted in July 2019. While the dam's emergency action plan status and risk assessment details are currently unspecified, its compliance with state permitting, inspection, and enforcement requirements underscores its commitment to safety and environmental stewardship.

Managed by a private entity, Roemer Lake Dam remains a vital infrastructure for water resource management and climate resilience in Warren County, Ohio. Its contribution to local recreation and its adherence to state regulations highlight its role in balancing human needs with environmental protection. As water enthusiasts and climate advocates, understanding the nuances of dam management and safety at Roemer Lake can inform ongoing discussions about sustainable water resource utilization and climate adaptation strategies in the region.

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.
