Summary

With a height of 30 feet and a storage capacity of 140 acre-feet, this pond serves multiple purposes, including flood control and water storage. The dam is regulated by the Oklahoma Water Resources Board and has a controlled spillway with a width of 1 foot.

Despite its low hazard potential and a very high risk assessment rating, Chisum Pond has not been rated for its condition assessment. The last inspection took place in May 2011, with a scheduled inspection frequency of 5 years. The emergency action plan for the dam is not specified, and no inundation maps or risk management measures are mentioned in the data. The risk assessment indicates a very high risk level, but further details on risk characterization and management are not provided.

For water resource and climate enthusiasts, Chisum Pond presents an interesting case study in dam infrastructure and risk assessment. With its location on the Verdigris River and a drainage area of 608 square miles, this dam plays a crucial role in water management in the region. Despite its relatively low hazard potential, the lack of recent condition assessments and emergency preparedness raises questions about the long-term safety and sustainability of this important water resource.

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.
