Summary
The dam stands at a height of 33 feet and has a storage capacity of 122 acre-feet, with a normal storage level of 109 acre-feet. Covering a surface area of 4.3 acres, the dam serves the purpose of managing tailings from the Collins Park Water Treatment Plant, contributing to the efficient operation of the facility.
Managed by the local government and regulated by the Ohio Department of Natural Resources, Collins Park Wtp Sludge Lagoon E has been assessed to be in fair condition with a significant hazard potential. With a last inspection date in October 2019, the dam is subject to regular inspections every five years to ensure its structural integrity and safety. Despite its fair condition, the dam plays a crucial role in the management of tailings, highlighting the importance of effective water resource infrastructure in mitigating environmental impacts and ensuring water quality for the community.
With its location near the Otter Creek and offstream, Collins Park Wtp Sludge Lagoon E stands as a vital component of the water management system in Lucas County, Ohio. Designed by Finkbeiner, Pettis & Strout, Ltd., the dam represents a key piece of infrastructure that supports the operations of the water treatment plant. As climate change continues to impact water resources, the maintenance and monitoring of structures like Collins Park Wtp Sludge Lagoon E become increasingly important in safeguarding water quality and ensuring the resilience of the local water supply system.

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.
