Summary

Built in 1966 by the Bureau of Reclamation, this gravity-type dam stands at a height of 15 feet and has a structural height of 16 feet. Its primary purpose is for water supply, with a storage capacity of 226,450 acre-feet and a surface area of 3,127 acres.

The dam is situated on Rock Creek in Murray County, Oklahoma, and is under the jurisdiction of the state. Despite its high hazard potential, with a very high risk assessment rating, the dam has not been inspected or assessed since 1992. The spillway type is controlled, with a spillway width of 4 feet and one outlet valve. With a maximum discharge capacity of 3,410 cubic feet per second, Arbuckle Dike 2 plays a crucial role in managing water resources in the region.

As a key infrastructure for water supply, Arbuckle Dike 2 serves as a vital resource for the community. Its location in a high-risk area highlights the importance of regular inspections and maintenance to ensure the safety and sustainability of the dam. Climate enthusiasts and water resource experts alike can appreciate the significance of this dam in managing water resources and mitigating potential risks associated with high hazard potential and very high risk assessment ratings.

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.
