Summary
Constructed in 2004 by the USDA NRCS, this earth dam stands at a height of 17 feet and has a storage capacity of 77.18 acre-feet. With a normal storage capacity of 26 acre-feet and a surface area of 10.6 acres, this dam plays a crucial role in managing water resources in the area.
The dam features a controlled spillway and a single valve outlet gate, with a hazard potential rated as "Low" and a condition assessment listed as "Not Rated". Despite these designations, the risk assessment for Oknoname 30124 is marked as "Very High (1)". The dam has not been modified since its completion and is under the jurisdiction of the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place to ensure its safety and regulatory compliance.
With its unique design and important role in water management for the region, Oknoname 30124 serves as a key infrastructure for both water resource management and climate resilience efforts in Oklahoma. The dam's presence on West Barnitz Creek and its controlled spillway highlight the importance of effective water infrastructure in addressing the challenges of a changing climate and maintaining water security for the community of Butler and beyond.

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.
