Summary
Completed in 1964, this gravity dam primarily serves the purpose of debris control along the Okie Draw river. With a structural height of 26 feet and a hydraulic height of 17 feet, the dam spans 730 feet in length and has a storage capacity of 170 acre-feet.
Despite being classified as having a low hazard potential, the condition assessment of Okie Draw Dam is currently marked as unsatisfactory. The last inspection in July 2017 revealed areas in need of improvement, prompting a moderate risk assessment rating. While the dam does not have outlet gates or locks, it does feature an uncontrolled spillway with a width of 2 feet to manage maximum discharges of up to 660 cubic feet per second.
Water resource and climate enthusiasts may find Okie Draw Dam an intriguing subject for study, given its unique design elements and the ongoing efforts to address its condition assessment. As a vital infrastructure for debris control in the region, the dam's management and maintenance by the Bureau of Land Management highlight the intersection of environmental conservation and engineering in water resource management. Despite its challenges, Okie Draw Dam stands as a testament to the importance of sustainable water infrastructure in mitigating natural hazards and protecting communities downstream.

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.
