Summary

The dam stands at a height of 38 feet with a structural height of 46 feet and a length of 356 feet, providing a storage capacity of 160 acre-feet. Situated on Chicken Creek in Blaine County, the dam has a low hazard potential and is regulated by the Oklahoma Water Resources Board.

Although the dam has not been rated for its condition, it is inspected every 5 years to ensure its safety and functionality. With a very high risk assessment rating, the dam is deemed to be of utmost importance for risk management measures. The spillway, controlled and 2 feet wide, helps regulate the maximum discharge of 28 cubic feet per second in case of emergencies.

Overall, Chris Didier Dam plays a crucial role in the irrigation system of the area, providing essential water resources for agricultural purposes. Its strategic location and design make it a vital asset for water management in Oklahoma, contributing to the sustainability and resilience of the local ecosystem in the face of changing climate conditions.

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.
