Summary
The dam, standing at 23 feet high with a structural height of 28.3 feet, serves to impound Deer Creek and has a storage capacity of 68.05 acre-feet. With a normal storage level of 22 feet and a surface area of 4.3 acres, the dam plays a crucial role in managing water resources in the region.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular state inspections to ensure its safety and compliance with regulations. Despite being classified as low hazard potential, a very high risk assessment rating indicates the importance of proper risk management measures. The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 56.7 cubic feet per second. Its strategic location along Deer Creek contributes to its significance in water resource management for the area.
Overall, Oknoname 30193 serves as a key infrastructure for water supply in Custer City, Oklahoma, with its earth dam structure built on a stone core foundation. The collaborative efforts of private ownership, state regulation, and federal design by the USDA NRCS highlight the importance of effective water resource management and infrastructure development. With a focus on safety and risk management, the dam plays a vital role in safeguarding the local community and environment while ensuring reliable water supply for various purposes.

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.
