Summary
Canadian River. Completed in 1953, this irrigation dam stands at 20 feet high and spans 400 feet in length, with a storage capacity of 205 acre-feet. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections to ensure its structural integrity.
Despite being rated as having low hazard potential, Headrick No.1 is categorized as having a very high risk due to its age and location. The dam features a controlled spillway and a single valve outlet gate. Even though it has not been assessed for its current condition, the dam is still considered to be in good standing. The surrounding area is at risk of inundation in case of a breach, making it essential for emergency preparedness and risk management measures to be put in place.
Enthusiasts of water resources and climate will find Headrick No.1 to be an intriguing structure, showcasing the importance of proper dam management and maintenance in ensuring the safety of communities and the environment. With its historical significance and vital role in irrigation, this dam serves as a reminder of the delicate balance between harnessing water resources for human use and protecting against potential risks associated with dam failure.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
