Summary
This dam, completed in 1960, serves a primary purpose that falls under the "Other" category and is classified as an Earth dam with stone core types and soil foundations. It has a height of 35 feet, a length of 330 feet, and a storage capacity of 74 acre-feet, with a normal storage level of 42 acre-feet.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, with a low hazard potential and a very high risk assessment rating. Despite its age, McCurdy Wc remains in good condition, as it has not been rated for its current condition. The dam features a controlled spillway and one valve outlet gate, with a maximum discharge capacity of 2,760 cubic feet per second. The surrounding area covers approximately 7 acres and is situated along the TR-Turkey Creek, under the jurisdiction of the Tulsa District of the US Army Corps of Engineers.
Overall, McCurdy Wc represents a critical water management infrastructure in the region, ensuring water storage and flood control for the surrounding area. With its historical significance and ongoing regulatory oversight, this dam continues to play a vital role in safeguarding water resources and mitigating potential risks associated with its operation. For water resource and climate enthusiasts, McCurdy Wc serves as a compelling example of the intersection between human infrastructure and environmental stewardship in managing water systems.

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.
