Summary
The dam, primarily constructed of earth, serves the Big Creek Drainage Canal and has a normal storage capacity of 62 acre-feet. With a low hazard potential and a moderate risk assessment rating of 3, Williams has not been subject to a condition assessment and is currently deemed as "Not Rated."
While the dam has not been regulated or inspected by the state, it falls under the jurisdiction of the Memphis District of the US Army Corps of Engineers. Despite the lack of state oversight, Williams has a maximum storage capacity of 105 acre-feet, covering a surface area of 10.4 acres. The dam features an uncontrolled spillway and has not been modified in recent years. With no associated structures or outlet gates, Williams remains a key feature in the water resource management of the area.
Although no emergency action plan (EAP) has been prepared for Williams, the dam meets moderate risk management guidelines. As of the last inspection in December 2020, the dam's condition assessment remains unknown. With a designated inspection frequency of 5 years, Williams continues to play a crucial role in flood control and water resource management within the region, under the supervision of the Memphis District of the US Army Corps of Engineers.

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.
