Summary
The dam holds a maximum storage capacity of 210 acre-feet and serves the West Red Bluff Creek watershed. With a dam height of 22 feet and a length of 900 feet, Miller Dam plays a crucial role in managing water resources in the region.
Although the dam has a low hazard potential, it is regulated and inspected by the Oklahoma Water Resources Board to ensure its safety and functionality. The spillway, which is controlled and 1 foot wide, helps manage water flow during periods of high discharge. The dam is equipped with a valve outlet gate for water release, and while its condition is currently not rated, it undergoes inspections every 5 years to ensure compliance with regulatory standards.
For water resource and climate enthusiasts, Miller Dam serves as a vital infrastructure for irrigation and water storage in Ellis County. Its location in the West Red Bluff Creek watershed and association with the Tulsa District highlight its significance in managing water resources in the region. Despite its low hazard potential, the dam is subject to regular inspections and regulatory oversight to maintain its integrity and functionality for the community it serves.

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.
