Summary
Built in 1969 by the USDA NRCS, this earth dam stands at a height of 60 feet and spans a length of 3624 feet, providing critical protection to the surrounding area from potential flooding events. The dam has a maximum storage capacity of 10,000 acre-feet and serves a drainage area of 23.23 square miles, with a spillway width of 4 feet to control water flow.
With a hazard potential rated as high and a risk assessment indicating a very high level of risk, the SCS-Upper Elk Creek Site-22r is closely monitored and inspected by the state regulatory agency, OWRB. Despite being classified as in fair condition, the dam is equipped with necessary safety features such as a slide (sluice gate) outlet gate and an emergency action plan for potential incidents. The surrounding community in Port, Oklahoma relies on the protection provided by this dam to mitigate flood risks and safeguard their water resources, making it an essential piece of infrastructure in the region.

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.
