Summary

Completed in 1957, this earth dam stands at a height of 25 feet and has a storage capacity of 60 acre-feet. It is regulated by the Oklahoma Water Resources Board and is subject to state inspections and enforcement measures. The dam's primary purpose is classified as 'Other', with a spillway type of 'Controlled'.

The Wickham R No 4 dam poses a low hazard potential but is categorized as having a very high risk level. Despite its age, the dam's condition has not been rated, and its last inspection took place in November 2010. The emergency action plan status is unknown, and there are no inundation maps prepared for the area. The dam's outlet gates consist of one valve, and it is not associated with any other structures in the vicinity.

Climate and water resource enthusiasts may be interested in Wickham R No 4 due to its location on the Wilhorse Creek in Roger Mills County, Oklahoma. The dam plays a crucial role in water management in the area, with a maximum discharge capacity of 1470 cubic feet per second. While the risk level is high, the dam's low hazard potential suggests that it may not pose an immediate threat to surrounding communities. Ongoing inspections and enforcement measures aim to ensure the safety and integrity of this essential water resource infrastructure.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
