Summary
This dam, designed for the primary purpose of "Other", stands at a height of 30 feet and has a storage capacity of 130 acre-feet. The dam is regulated, permitted, inspected, and enforced by the Oklahoma Water Resources Board (OWRB), ensuring its safety and compliance with state regulations.
The dam's spillway type is controlled, with a spillway width of 1 foot, and it is equipped with a single valve outlet gate. Oakes No 1 has a low hazard potential and its condition is currently not rated. Despite being in operation for over four decades, the dam has a very high risk assessment score of 1, indicating the need for vigilant risk management measures in the event of an emergency. The dam is located on Trail Creek and is under the jurisdiction of the Tulsa District of the US Army Corps of Engineers.
Water resource and climate enthusiasts interested in the infrastructure and management of dams will find Oakes No 1 to be a fascinating case study. This earth dam in Oklahoma serves as a critical water storage structure, with a capacity to hold 130 acre-feet of water. The dam's design and construction by the Natural Resources Conservation Service reflect a commitment to sustainable water resource management. With a low hazard potential but a high risk assessment score, Oakes No 1 highlights the importance of ongoing monitoring and maintenance to ensure the safety and integrity of water infrastructure in the face of changing climate conditions.

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.
