Summary
With a height of 23 feet and a length of 710 feet, it has a storage capacity of 350 acre-feet and a surface area of 17 acres. The dam features a controlled spillway with a width of 1 foot and an outlet gate consisting of a single valve.
Despite being classified as having a low hazard potential, Oknoname 049003 is deemed to have a very high risk level, with a risk assessment rating of 1. The dam is regulated by the Oklahoma Water Resources Board (OWRB), with state jurisdiction, permitting, inspection, and enforcement all in place. However, the condition of the dam is currently listed as "Not Rated", with the last inspection conducted in 2002 and an inspection frequency of every 5 years.
As a popular recreation spot in Maysville, Oklahoma, Oknoname 049003 serves as a crucial water resource for the local community. While the dam's risk level is a concern, its historical significance and contribution to the area's water supply make it a focal point for water resource and climate enthusiasts interested in the intersection between dam safety, recreational use, and environmental stewardship.

Dam Data Reference
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.
