Summary
Built in 1965, this Earth-type dam stands at a height of 27 feet and has a storage capacity of 80 acre-feet. With a maximum discharge of 2460 cubic feet per second, the dam serves a primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board (OWRB). Despite being rated as having a low hazard potential, the risk assessment for Davis No 1 is classified as "Very High (1)", highlighting the importance of proper maintenance and monitoring.
This dam is equipped with a controlled spillway and one outlet valve. It has been inspected every 5 years, with the last inspection taking place in August 2006. The condition of the dam is currently listed as "Not Rated", indicating a need for further assessment. Although the dam is not owned or funded by any federal agencies, it is subject to state permitting, inspection, and enforcement. With its location in a high-risk area, it is crucial for stakeholders to ensure that proper risk management measures are in place to address any potential threats to the structure and surrounding community.

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.
