Summary
Completed in 2011, this Earth-type dam stands at a height of 12.3 feet and has a storage capacity of 278.5 acre-feet, serving as a crucial component in the management of water resources in the area. With a drainage area of 0.04 square miles, the lagoon plays a significant role in controlling water flow and ensuring water quality in the tributary to the Auglaize River.
Despite its satisfactory condition assessment in 2017, the Auglaize River Wwt Lagoon has been identified as having a significant hazard potential. Regular inspections are conducted every five years to ensure its structural integrity and operational efficiency. Emergency action plans are in place to mitigate potential risks and protect the surrounding community in case of a dam failure. With its strategic location and design, this lagoon remains a crucial infrastructure for water management and climate resilience efforts in the region, providing a sustainable solution for water resource enthusiasts and climate advocates alike.

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.
