Summary
This earth dam, with a height of 10 feet and a storage capacity of 300 acre-feet, serves a primary purpose related to wastewater management. Despite being categorized as having a low hazard potential, the dam is subject to regular inspection, regulation, and enforcement by state authorities to ensure its continued safety and functionality.
This buttress-type dam features an uncontrolled spillway and is not currently rated for condition assessment. While it has a moderate risk level, with a risk management summary yet to be provided, the dam's emergency action plan status and inundation maps preparedness are unclear. With no outlet gates or associated structures, the Kosciusko Sewage Lagoon Number 1 Dam remains a critical component of the local water resource infrastructure, warranting ongoing monitoring and maintenance to mitigate potential risks and safeguard the surrounding community and environment.
As water resource and climate enthusiasts, understanding the significance of structures like the Kosciusko Sewage Lagoon Number 1 Dam in managing wastewater and protecting water quality is essential. With its specified purpose, design characteristics, and risk profile, this dam serves as a focal point for regulatory oversight and risk management efforts, highlighting the importance of proactive maintenance and emergency preparedness in ensuring the safety and sustainability of our water resources.

Dam Data Reference
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.
