Summary
Built in 1976 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along TR-House Creek. Standing at 35 feet in height with a hydraulic height of 30 feet, Clement Milford has a storage capacity of 75 acre-feet and a maximum discharge rate of 1162 cubic feet per second.
Managed by the Oklahoma Water Resources Board (OWRB), Clement Milford is regulated, permitted, inspected, and enforced by the state. The dam features a controlled spillway and one outlet valve, with a low hazard potential and a risk assessment rating of "Very High (1)". While the condition assessment is currently listed as "Not Rated", the dam undergoes inspections every five years to ensure its structural integrity and safety. Despite being a private structure, Clement Milford plays a crucial role in mitigating flood risks in the region and is an important asset for water resource and climate enthusiasts to study and monitor.
With its historical completion in the mid-1970s and ongoing state regulation and inspections, Clement Milford remains a key feature in the flood risk reduction infrastructure of Marshall County, Oklahoma. As part of the overall flood management strategy in the area, this earth dam constructed by the Natural Resources Conservation Service continues to be a vital component in protecting communities and properties along TR-House Creek. As climate change intensifies and water resources face increasing pressures, understanding and maintaining structures like Clement Milford are essential for ensuring the resilience and safety of the surrounding environment and residents.

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.
