Summary

Completed in 1972, this dam stands at 37 feet high and has a storage capacity of 1190 acre-feet, with a normal storage level of 234 acre-feet. The dam has a controlled spillway and a single valve outlet gate for water release.

Despite being rated as having a low hazard potential, this dam has a very high risk assessment due to its age and lack of recent inspections. The condition of the dam is currently not rated, and it is unclear if an Emergency Action Plan (EAP) has been prepared or updated recently. The risk management measures and inundation maps for the area have not been documented, highlighting the need for further assessment and planning to ensure the safety and integrity of this critical water resource infrastructure.

Given its location in a high-risk area and the potential consequences of failure, it is imperative that the state regulatory agency, OWRB, conducts regular inspections and maintenance of SCS-Fort Cobb Laterals Site-012. Climate enthusiasts and water resource experts should closely monitor the condition and management of this dam to prevent any potential disasters and ensure the safety of the surrounding community and environment.

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.
