Summary
The dam has a controlled spillway type with a width of 2 feet and is equipped with a single valve outlet gate. Despite its low hazard potential, Shadwick has a very high risk assessment rating, emphasizing the importance of ongoing monitoring and maintenance.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and falls under state jurisdiction for permitting, inspection, and enforcement. The last inspection of Shadwick took place in December 2010, with an inspection frequency of 5 years. The condition assessment of the dam is currently listed as "Not Rated," highlighting the need for further evaluation to ensure its structural integrity and safety. While the dam has not been modified in recent years, its risk management measures and emergency preparedness plans are not clearly defined, indicating a potential area for improvement in ensuring the safety of the surrounding community and environment.
Overall, Shadwick stands as a critical infrastructure component in the water resource management of Le Flore County, Oklahoma. With its strategic location on Coal Creek and significant storage capacity, ongoing monitoring and maintenance efforts are essential to mitigate the very high risk assessment associated with the dam. Collaboration between the private owner, state regulatory agencies, and local stakeholders will be crucial in implementing effective risk management measures and emergency response plans to safeguard against potential hazards and ensure the long-term sustainability of this vital water resource infrastructure.

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.
