Summary
is a privately owned dam located in Stephens, Oklahoma, specifically at the ST HWY 7 BRIDGE on TR STAGE STAND CREEK. Built in 1965, this Earth dam stands at a height of 23 feet with a hydraulic height of 18 feet and a length of 565 feet. It has a storage capacity of 114 acre-feet and a maximum discharge of 2080 cubic feet per second. Despite its low hazard potential, it is classified as having a very high risk due to its condition assessment not being rated.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and receives state permitting, inspection, and enforcement. The primary purpose of Johnson R.E. is categorized as "Other," with its primary dam type being Earth with Stone core types and soil foundations. It has a controlled spillway with a width of 1 foot and one outlet gate valve. The dam is not associated with any federal agencies and has not undergone any modifications in recent years. The last inspection was conducted in September 2011, with a scheduled inspection frequency of 5 years.
Overall, Johnson R.E. is a significant structure that plays a crucial role in managing water resources in the region. Its presence ensures water storage and flood control for the surrounding area. With its state-regulated status and routine inspections, the dam continues to operate effectively despite its high-risk classification. Water resource and climate enthusiasts will find Johnson R.E. to be an interesting case study in dam management and regulation.

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.
