Summary
This earth dam was completed in 1935, with a structural height of 25 feet and a length of 327 feet, providing a storage capacity of 66 acre-feet. The dam is associated with the Bureau of Indian Affairs, who also handle the funding, design, construction, regulation, inspection, and operation of the structure.
Despite its relatively small size and storage capacity, South Okreek is deemed to have a high hazard potential. The dam does not have a spillway and its condition assessment is currently listed as "Not Available". There is no Emergency Action Plan (EAP) in place, and the inspection frequency is listed as 0. Given the lack of available data on the dam's current condition and risk management measures, further assessment and potential improvements may be necessary to ensure the safety and reliability of the structure for both the surrounding community and the environment.
For water resource and climate enthusiasts, South Okreek presents an interesting case study in dam management and safety. With its location in Todd County, near the Oak Creek stream, the dam serves multiple purposes including fire protection, stock watering, and recreational activities in addition to its primary function as a fish and wildlife pond. The presence of a high hazard potential underscores the importance of proactive maintenance and monitoring to mitigate any potential risks associated with the structure, making it a valuable site for ongoing research and analysis in the field of water resource management.

Dam Data Reference
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.
