Summary

Completed in 1978, the lagoons have a storage capacity of 625 acre-feet and cover a surface area of 33 acres. Situated along Big Walnut Creek - Offstream, the lagoons are regulated by the Department of Natural Resources and undergo regular inspections to ensure their structural integrity.

Despite being classified as a significant hazard potential structure, Parsons Avenue Sludge Lagoons boast a satisfactory condition assessment as of December 2020. With a drainage area of 0.05 square miles, these lagoons play a crucial role in managing tailings and wastewater in the region. The lagoons have a normal storage capacity of 560 acre-feet and are designed as earth dams, highlighting their importance in water resource management and environmental protection efforts in Franklin County, Ohio.

As climate change poses increasing challenges to water resources, the Parsons Avenue Sludge Lagoons stand as a vital infrastructure ensuring proper tailings storage and disposal. The lagoons' adherence to state regulations and their regular inspections signify a commitment to environmental stewardship and public safety. With their strategic location and significant storage capacity, these lagoons play a crucial role in mitigating potential environmental risks and ensuring sustainable water management practices in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
