Summary
This Earth-type dam was completed in 1978 and has a height of 25 feet, providing a storage capacity of 50 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections to ensure its structural integrity and safety.
Despite being classified as having a low hazard potential, Davis Elvin J is considered to have a very high risk due to its location and the potential consequences of failure. The dam features a controlled spillway and one valve outlet gate, with a spillway width of 1 foot. The surrounding area has a surface area of 2 acres and is part of the TR Trail Creek watershed. While the dam has not been rated for its condition, it is subject to regular inspections every 5 years to monitor any changes in its risk profile.
Overall, Davis Elvin J serves a crucial role in mitigating flood risks in the area and is under the jurisdiction of the state regulatory agency, OWRB. With its strategic location and design features, this dam plays a vital role in protecting the surrounding community from potential flooding events. Climate and water resource enthusiasts would find this information valuable in understanding the role of dams in managing water resources and mitigating climate-related risks.

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.
