Summary

Built in 1960 by the USDA NRCS, this Earth-type dam stands at a height of 43 feet and has a hydraulic height of 38 feet, providing storage for up to 1,054 acre-feet of water. With a controlled spillway and a low hazard potential, this dam plays a critical role in managing the water resources in the area, particularly along the TR-Dead Indian Creek.

Despite its age, SCS-Dead Indian-Wldhorse Cr Site-05 has not been inspected since 1980, with a scheduled inspection frequency of every 5 years. The dam is currently rated as "Not Rated" in terms of condition assessment, and while it has not experienced any modifications in recent years, its risk assessment remains high due to its very high risk level (1). With one valve outlet gate and a surface area of 47 acres, this dam serves as a vital infrastructure for flood control and water management in the region, under the oversight of the Oklahoma Water Resources Board (OWRB).

As climate change continues to impact water resources and the frequency of extreme weather events, the maintenance and upkeep of structures like SCS-Dead Indian-Wldhorse Cr Site-05 become increasingly crucial. With adequate state regulatory oversight and enforcement, as well as regular inspections and risk assessments, this dam plays a vital role in protecting downstream communities from flooding and ensuring the sustainable management of water resources in Roger Mills, Oklahoma.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
