Summary
Constructed in 1965 by the USDA NRCS, this earth dam on TR-LONG CREEK serves various purposes beyond traditional water storage. With a height of 26 feet and a capacity of 50 acre-feet, Mcnaught plays a crucial role in flood control and water conservation efforts in the area.
Managed by the Oklahoma Water Resources Board, Mcnaught is regulated, inspected, and enforced to ensure its structural integrity and safety. Despite its low hazard potential, the dam has a very high risk assessment rating, reflecting the importance of proper management and maintenance. With a controlled spillway and a single valve outlet gate, Mcnaught is equipped to handle maximum discharge of 250 cubic feet per second, making it a vital component of the local water infrastructure.
While Mcnaught's condition assessment is currently not rated, its risk management measures are under constant evaluation to mitigate potential threats. As a key structure in the Tulsa District, this dam serves as a crucial resource for the surrounding community, highlighting the intersection of water resource management, climate resilience, and environmental sustainability.

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.
