Summary
Built in 1960, this earth dam stands at 30 feet in height and spans 400 feet in length, with a storage capacity of 90 acre-feet. Situated on the TR-West Fork Sandy Creek, this dam is regulated by the Oklahoma Water Resources Board and is subject to state inspection and enforcement.
Although classified as having a low hazard potential, this dam poses a very high risk due to its condition assessment not being rated. With a controlled spillway and valve outlet gates, Mcadams T.R. is equipped to handle a maximum discharge of 1700 cubic feet per second. Despite its risk level, this dam has not been modified in recent years and is in need of further assessment to ensure its safety and effectiveness in managing water resources in the region.
For water resource and climate enthusiasts, Mcadams T.R. presents an intriguing case study of a recreational dam in Oklahoma with a complex regulatory framework. With its proximity to the TR-West Fork Sandy Creek, this dam plays a crucial role in managing water flow and storage in the area. As efforts continue to assess and mitigate the risks associated with this dam, stakeholders are encouraged to stay informed and engaged in the ongoing management of this vital water resource infrastructure.

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.
