Summary
4, located in Crawford County, Ohio, is a vital water supply resource managed by the local government. Constructed in 1983 by the esteemed firm Burgess & Niple, this earth dam stands at a height of 29 feet and boasts a storage capacity of 4,626 acre-feet. With a primary purpose of water supply, the reservoir covers a surface area of 150 acres and serves as a critical source of water for the surrounding community.
Maintained and regulated by the Ohio Department of Natural Resources, Bucyrus Upground Reservoir No. 4 is subject to regular inspections to ensure its structural integrity and operational efficiency. Despite being classified as having a high hazard potential, the dam's condition assessment as of May 2018 was deemed satisfactory, indicating that it is currently in a stable and safe state. With a maximum discharge rate of 64 cubic feet per second, the reservoir plays a crucial role in managing water resources and mitigating potential risks associated with water supply management in the region.
Located just 2.7 miles away from the city of Bucyrus, this offstream reservoir plays a pivotal role in the local water infrastructure. As climate change continues to impact water resources, the maintenance and regulation of structures like Bucyrus Upground Reservoir No. 4 are essential in ensuring the sustainability and resilience of water supply systems in the face of changing environmental conditions.

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.
