Summary
Constructed in 1972 by USDA NRCS, this dam stands at a height of 31 feet and has a length of 790 feet. With a maximum storage capacity of 400 acre-feet and a normal storage of 51 acre-feet, this structure plays a crucial role in managing water resources in the area.
The dam on TR-ROCK CREEK is equipped with a controlled spillway and a single valve outlet gate. Despite being rated as low hazard potential, the risk assessment for this site indicates a very high risk level. The dam has not been inspected since January 1980, with an inspection frequency of 5 years. While the condition assessment is currently not rated, the structure is under the jurisdiction of the Oklahoma Water Resources Board and is subject to state permitting, inspection, and enforcement.
This site, within the Tulsa District and owned by the state, serves as a key infrastructure for flood control in the region. As climate change impacts intensify, the management and maintenance of such water resource facilities become increasingly vital to ensure the safety and resilience of communities in the face of extreme weather events.

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.
