Summary
The lagoon was completed in 1995 and serves as a water resource management system for an unnamed tributary to Sycarmore Run. With a maximum storage capacity of 83 acre-feet and a surface area of 8.5 acres, the lagoon plays a crucial role in water containment and treatment in the region.
Managed by the Department of Natural Resources in Ohio, the Waynoka Wwt Lagoon is subject to state regulations, inspections, and enforcement to ensure its structural integrity and environmental impact. With a significant hazard potential but deemed to be in satisfactory condition during the last assessment in May 2018, the lagoon has a regular inspection frequency of 5 years. It is crucial for water resource and climate enthusiasts to monitor the lagoon's condition and risk management measures to protect the surrounding ecosystem and water quality.
As part of the local government's infrastructure, the Waynoka Wwt Lagoon serves as a vital component in controlling water discharge, with a maximum discharge rate of 5 cubic feet per second. Despite its relatively small drainage area of 0.01 square miles, the lagoon plays a significant role in mitigating flood risks and ensuring water quality in the region. For enthusiasts interested in water resource management and climate resilience, understanding the design, purpose, and condition of the Waynoka Wwt Lagoon provides valuable insights into sustainable water infrastructure development and management practices.

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.
