Summary
Built in 1950, the dam stands at a height of 40 feet and has a storage capacity of 190 acre-feet. The dam serves a primary purpose that is classified as "Other", with a spillway type of "Controlled" and a hazard potential rated as "Low". Despite being in operation for several decades, the dam's condition assessment remains "Not Rated", and it has not undergone recent modifications or updates.
The dam's location in Grady County, Oklahoma, under the jurisdiction of the OWRB, places it within the Tulsa District of the US Army Corps of Engineers. Despite a "Very High (1)" risk assessment, the dam has not had an Emergency Action Plan (EAP) prepared or updated, and there is no record of inundation maps or risk management measures in place. The last inspection date was in 2010, with an inspection frequency of 5 years, indicating a potential need for increased monitoring and maintenance to address the identified risks associated with the dam.
As an important structure for water resource management in the area, Oknoname 051061's data highlights the need for continued oversight and potential improvements to ensure the safety and effectiveness of the dam in mitigating flood risks and providing water storage. Climate and water resource enthusiasts may find interest in further exploration of the dam's history, current condition, and regulatory oversight to understand its role in the local ecosystem and the potential impacts of climate change on its operations.

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.
