Summary

Constructed in 1960 by the USDA NRCS, this dam stands at a height of 45 feet and has a hydraulic height of 39 feet. It has a storage capacity of 290 acre-feet and a normal storage level of 145 acre-feet, covering a surface area of 33 acres. The dam is regulated by the Oklahoma Water Resources Board and has a low hazard potential, with a very high risk assessment ranking.

Despite being last inspected in 1980, this dam remains in a condition that has not been rated. It has an outlet gate consisting of one valve and a controlled spillway with a width of 1 foot. While the dam is not under the jurisdiction of a federal agency, it is subject to state regulation, permitting, inspection, and enforcement by the OWRB. The surrounding area is at a very high risk of flooding, emphasizing the importance of maintaining and monitoring the structural integrity of SCS-Lost Duck Creek Site-D2 for the safety of the community and water resources in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
