Summary
The dam, completed in 1984, stands at 25 feet in height and serves a primary purpose of "Other," with a storage capacity of 50 acre-feet. Classified as an Earth dam with a Stone core and soil foundation, Miller James is equipped with a controlled spillway and a single valve outlet gate.
Despite being rated as having a low hazard potential, the risk assessment for Miller James indicates a very high risk level, emphasizing the importance of regular inspections and proper risk management measures. The dam's last inspection took place in July 2011, with an inspection frequency of 5 years. While the condition assessment is currently marked as "Not Rated," the dam's emergency action plan status, inundation maps, and overall risk management strategies appear to be lacking updated information.
Situated on Deer Creek within the Tulsa District, Miller James serves as a crucial structure for water resource management in the region. With its historical significance dating back to the 1980s, this dam represents a key component of the local water infrastructure that warrants ongoing attention and oversight to ensure its continued safety and functionality in the face of evolving climate conditions and potential risks.

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.
