Summary
Completed in 1966, this structure stands at a height of 26 feet and has a maximum storage capacity of 50 acre-feet. It serves primarily for purposes other than flood control or water supply, with a spillway designed for controlled release of water in case of excess inflow.
Managed by the Oklahoma Water Resources Board, Woldridge is classified as having a low hazard potential, but a very high risk assessment due to its critical location and structural characteristics. Despite not being rated for condition assessment, the dam undergoes regular inspections every 5 years to ensure its safety and functionality. With one valve for outlet gates and a drainage area connected to the TR-Horse Creek stream, Woldridge plays a crucial role in water resource management for the region.
Enthusiasts of water resources and climate will find Woldridge to be an intriguing case study in dam infrastructure, with a unique design featuring stone core and soil foundation. Located within the Tulsa District of Oklahoma, this dam may not be the largest in terms of size, but its importance in managing water flow and storage cannot be understated. As climate change continues to impact water resources, monitoring and maintaining structures like Woldridge becomes increasingly vital for sustainable water management practices in the region.

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.
