Summary
This dam, designed for flood risk reduction along the TR-Elk Creek, stands at a height of 22 feet and has a normal storage capacity of 34 acre-feet. With a low hazard potential and a very high risk assessment rating, this dam is regulated by the Oklahoma Water Resources Board and undergoes regular state inspections and enforcement measures to ensure its safety and functionality.
The dam features a controlled spillway and a single valve outlet gate, with a hydraulic height of 19 feet and a length of 1020 feet. The surrounding area covers 10 acres, serving a maximum discharge of 975 cubic feet per second. Despite not having a current condition assessment, this dam remains a crucial asset for flood control in the Washita County area. While it may not have undergone recent modifications or assessments, its state-regulated status and continuous state oversight ensure its ongoing operational reliability.
As water resource and climate enthusiasts, the information on SCS-Upper Elk Creek Site-39 provides insight into the management and infrastructure of flood risk reduction in Oklahoma. The dam's design and purpose, along with its state ownership and regulatory framework, highlight the importance of sustainable water resource management and the critical role of state agencies in maintaining the safety and integrity of vital water infrastructure. The data on this dam serves as a reminder of the ongoing efforts to protect communities and ecosystems from the impacts of extreme weather events and changing climate conditions.

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.
