Summary
Built in 1958 by the USDA NRCS, this dam serves as a crucial flood risk reduction structure along the TR-Mill Creek river. With a height of 20 feet and a storage capacity of 314 acre-feet, it plays a significant role in managing water flow and protecting downstream areas from flooding.
Managed by the Oklahoma Water Resources Board, SCS-Mill Creek Site-05 boasts a controlled spillway and a single valve outlet gate. Despite its low hazard potential, the dam is classified as having a very high risk due to its age and lack of recent condition assessments. While it has not been modified in recent years, its regular inspection schedule ensures that it remains in operational condition to fulfill its primary purpose of flood risk reduction.
This dam is part of the Fort Worth District and is under the jurisdiction of the state regulatory agency OWRB. Although its condition is currently not rated, its strategic location and design make it a critical component of the region's water resource and climate management infrastructure. With ongoing monitoring and maintenance, SCS-Mill Creek Site-05 continues to contribute to the safety and well-being of the surrounding community.

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.
