Summary
Completed in 1964, this dam stands at a height of 45 feet and has a length of 1310 feet, providing a normal storage capacity of 200 acre-feet and a maximum storage of 1844 acre-feet. The dam, situated on Browns Creek, is under the oversight of the Oklahoma Water Resources Board and is inspected every 5 years to ensure its structural integrity.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Little Deep Fork Creek Site-54 indicates a very high risk level (1). With a controlled spillway and a single valve outlet gate, this dam plays a crucial role in mitigating flood risks in the region. However, the condition assessment is currently listed as "Not Rated," highlighting the need for further evaluation and potential maintenance to ensure the continued effectiveness of this essential water resource infrastructure.
Water resource and climate enthusiasts will appreciate the significance of SCS-Little Deep Fork Creek Site-54 in managing flood risks and protecting the surrounding area from potential inundation. As part of the flood risk reduction infrastructure in Okmulgee County, Oklahoma, this earth dam serves as a vital component of the state's water resource management strategy. With its location on Browns Creek and its impressive storage capacity, this dam exemplifies the importance of proactive inspection and maintenance to safeguard communities and ecosystems from the impacts of extreme weather events and changing climate patterns.

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.
