Summary
Constructed in 1920 by the USDA NRCS, this Earth dam stands at 15 feet tall and spans 700 feet in length. The lake has a storage capacity of 150 acre-feet and is primarily used for recreation purposes.
The dam at Williams Lake poses a significant hazard potential with a moderate risk assessment rating of 3. While the condition of the dam is not rated, it is important to note that it is uncontrolled in terms of spillway type and outlet gates. Despite the lack of state regulation and inspection, the Vicksburg District of the USACE has not been involved in the management or funding of this structure.
Water and climate enthusiasts visiting Williams Lake can enjoy the natural beauty of the surroundings and engage in recreational activities such as fishing, boating, and wildlife viewing. However, caution should be exercised due to the significant hazard potential of the dam and the lack of regular maintenance and oversight. The lake's proximity to TR-PORTER CREEK and the city of EDWARDS adds to its appeal for outdoor enthusiasts seeking a peaceful escape in the heart of Mississippi.

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.
