Summary
This lagoon, completed in 1997, serves as an Earth-type dam with a height of 10 feet and a storage capacity of 80.5 acre-feet. With a surface area of 8.1 acres and a drainage area of 0.02 square miles, this lagoon plays a crucial role in managing water resources in the region.
The primary purpose of West Mansfield Wwt Lagoon is classified as 'Other', and it is used for various purposes including water management and environmental protection. The lagoon has a significant hazard potential and is classified as in fair condition as of the last assessment in November 2020. With a regular inspection frequency of 5 years, this lagoon ensures the safety and efficiency of its operations while meeting state regulatory standards. Furthermore, it is situated near an unnamed tributary to Bloke Creek, highlighting its importance in the local water ecosystem.
Managed by the local government and designed by Poggemeyer Design Group, West Mansfield Wwt Lagoon stands as a vital infrastructure supporting the water resource management efforts in Logan County, Ohio. With its completion in 1997, this lagoon has been instrumental in flood control, water storage, and environmental conservation in the region. Its consistent inspection and regulatory compliance demonstrate a commitment to ensuring the sustainability and resilience of the local water resources in the face of climate challenges and 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.
