Summary
Completed in 1974, this dam stands at a height of 41 feet and has a length of 5350 feet, providing a storage capacity of 1940 acre-feet. With a controlled spillway and a maximum discharge of 4000 cubic feet per second, this dam plays a crucial role in managing water flow to protect the surrounding area from flooding.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Uncle John Creek Site-02 indicates a very high risk level, emphasizing the importance of regular inspections and maintenance. The dam is equipped with a slide gate for outlet control, and the last inspection was conducted in November 1997 with a scheduled frequency of every 5 years. While the condition assessment is currently not rated, the dam is under the jurisdiction of the Oklahoma Water Resources Board, ensuring that state regulations for inspection, enforcement, and permitting are being upheld to maintain the structural integrity and safety of the dam.
With its strategic location in the Tulsa District and vital role in flood risk reduction for the surrounding area, SCS-Uncle John Creek Site-02 serves as a key infrastructure managed by the Natural Resources Conservation Service. As water resource and climate enthusiasts, it is essential to monitor the condition and management of such dams to ensure their effectiveness in safeguarding communities against potential flooding events and to promote sustainable water resource management practices in the region.

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.
