Summary
Designed by the USDA NRCS and completed in 2003, this earth dam stands at a height of 27 feet and has a storage capacity of 24 acre-feet. With a low hazard potential and moderate risk assessment rating, the dam serves as a vital component in managing water resources in the area.
The dam features an uncontrolled spillway with a width of 10 feet and has not been rated for condition assessment. Despite its low hazard potential, the dam plays a crucial role in flood control and water management, protecting the surrounding area from potential risks. With a drainage area of 172.8 square miles, Miller Dam provides essential grade stabilization measures for the community of Shanes Dairy and contributes to the overall environmental health of Troublesome Creek.
Although Miller Dam has not undergone recent inspections or condition assessments, its construction and design by the Natural Resources Conservation Service reflect a commitment to water resource management and environmental conservation. As a key infrastructure in the area, the dam serves as a reminder of the importance of maintaining and monitoring water structures to ensure the safety and well-being of local communities and ecosystems in the face of climate change and evolving environmental challenges.

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.
