Summary
With a dam height of 30 feet and a storage capacity of 64 acre-feet, this structure serves the primary purpose of mitigating flooding in the area. Despite being state-regulated and not having a designated state jurisdiction, this dam presents a high hazard potential, although its condition assessment is currently not rated.
The dam, owned by a private entity, has not been inspected since September 1978, indicating a potential need for updated safety assessments. The emergency action plan (EAP) status and risk assessment for the dam are also unclear, raising questions about the level of preparedness in case of a catastrophic event. Additionally, the lack of inundation maps and assigned risk management measures suggests a need for improved monitoring and maintenance protocols to ensure the safety and effectiveness of the dam in the face of changing climate conditions.
For water resource and climate enthusiasts, Great Midwest Corp -Mononame 168 serves as a case study in the ongoing challenges of managing and maintaining aging infrastructure in the face of increasing environmental risks. With its location in a high-hazard area and limited regulatory oversight, this dam underscores the importance of proactive risk assessment and emergency preparedness measures to protect both the local community and the surrounding ecosystem from potential flooding events. Addressing the gaps in inspection frequency, emergency planning, and risk assessment for this dam will be crucial in ensuring its continued functionality and resilience in the years to come.

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.
