Summary
is a privately owned dam located in Stephens, Oklahoma, specifically at the ST HWY 7 BRIDGE over TR LITTLE BEAVER CREEK. Completed in 1980, this Earth type dam stands at a height of 25 feet and has a hydraulic height of 22 feet, with a maximum storage capacity of 50 acre-feet. The dam serves a primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board.
Despite its low hazard potential, Fredrick J.C. has been classified as having a very high risk due to its condition assessment being marked as "Not Rated." The dam features a controlled spillway with a width of 1 foot and an outlet gate consisting of a single valve. In terms of inspection, the dam is assessed every 5 years, with the last inspection taking place in September 2011. With its location in a high-risk area and lack of a current condition assessment, further monitoring and assessment of Fredrick J.C. is crucial for ensuring its safety and reliability in the face of potential climate impacts.

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.
