Lost Creek Upground Reservoir Reservoir Report
Last Updated: February 21, 2026
Lost Creek Upground Reservoir, located in Lima, Ohio, was completed in 1917 and is owned by the local government.
Summary
Managed by the Department of Natural Resources, this reservoir serves as a vital water supply source for the area. With a dam height of 38 feet and a storage capacity of 3113 acre-feet, it covers a surface area of 121 acres and has a drainage area of 0.19 square miles.
Despite its age, Lost Creek Upground Reservoir is in fair condition with a high hazard potential, as determined by a 2017 assessment. The dam, primarily made of earth, stands at 9880 feet in length and is subject to inspections every 5 years to ensure its structural integrity. Although no spillway width is specified, the reservoir's stability is maintained through state-regulated permitting, inspection, and enforcement protocols.
Lost Creek Upground Reservoir, situated along the Ottawa River, plays a crucial role in providing water for the local community. With its historical significance and ongoing monitoring for safety, this reservoir stands as a testament to the importance of sustainable water resource management in the face of changing climate conditions.

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.
