Summary
This private-owned Earth dam stands at a height of 24.9 feet and has a hydraulic height of 20.4 feet. With a storage capacity of 121 acre-feet and a surface area of 9.9 acres, the dam serves as a popular recreational spot in Marion County, offering opportunities for fishing, boating, and wildlife observation.
Although the dam poses a low hazard potential, its condition has not been rated in recent inspections. The last inspection took place in October 2017, with a frequency of every 5 years. Despite its moderate risk assessment level, the dam is not State-regulated and does not require permitting. This lack of regulation may raise concerns among water resource and climate enthusiasts, highlighting the importance of monitoring and maintaining the dam's integrity to ensure public safety and environmental protection.
With the dam's uncontrolled spillway and outlet gates, there is a need for ongoing risk management measures to mitigate potential hazards and ensure the safety of downstream communities. As the dam is not under the jurisdiction of federal agencies, it is crucial for the private owner to conduct regular inspections and emergency preparedness efforts. Lower Williams Lake Dam serves as a reminder of the importance of sustainable dam management practices in the face of changing climate conditions and increasing water resource demands.

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.
