Summary
is a privately-owned earth dam located in Stephens, Oklahoma, specifically in OAK GROVE CEMETERY along TR DRY CREEK. Built in 1970, this dam stands at a height of 25 feet and has a storage capacity of 50 acre-feet, with a maximum discharge of 1116 cubic feet per second. The dam serves a primary purpose of "Other" and is classified as having a low hazard potential, although it is considered to have a very high risk due to its structural and hydraulic characteristics.
Despite its low hazard potential, Williams R.E. is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular state inspections, with the last inspection dating back to August 2011. The dam features a controlled spillway and a valve outlet gate, with a surface area of 3 acres and a normal storage capacity of 42 acre-feet. Although the dam's condition assessment is currently listed as "Not Rated", its risk assessment is classified as very high, warranting close monitoring and potential risk management measures in the future to ensure the safety of the surrounding area and water resources.

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.
