Summary
The dam serves various purposes, with a normal storage capacity of 120 acre-feet and a maximum storage capacity of 193 acre-feet. It is situated on the TR-Wolf Branch of Big Creek and falls under the jurisdiction of the Rock Island District of the US Army Corps of Engineers.
Despite its low hazard potential and current "Not Rated" condition assessment, Miller Lake Dam lacks recent inspection data and emergency preparedness measures such as an Emergency Action Plan. The dam has not been modified or updated in recent years, raising concerns about its long-term safety and resilience to changing climate conditions. Climate enthusiasts and water resource experts may find interest in monitoring the dam's risk management measures and potential environmental impacts.
With its unique design as a Buttress Earth dam, Miller Lake Dam presents an opportunity for further study and evaluation in the context of water resource management and climate change adaptation. As climate-related risks continue to increase, understanding the condition and potential vulnerabilities of dams like Miller Lake will be crucial for ensuring the safety and sustainability of water resources in the region.

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.
