Summary
Standing at a height of 26 feet with a length of 434 feet, this earth dam provides a normal storage capacity of 85 acre-feet and a maximum storage of 101 acre-feet. Despite not having a spillway, the dam plays a vital role in fire protection, stock, small fish pond management, and recreational activities in the area.
Owned privately, Williams Lake Dam is not regulated by the state but undergoes regular inspections to ensure its functionality and safety. With a high hazard potential rating, the dam has not been formally rated for its condition assessment, but its risk management measures are yet to be determined. The dam's emergency action plan status and inundation maps preparedness are also currently unavailable, highlighting a need for further risk assessment and management strategies to safeguard the surrounding community and environment from potential hazards.
In the midst of ongoing data updates and risk assessments, Williams Lake Dam remains a significant structure in the Galveston District, serving as a key element in flood risk mitigation and water resource management. With its rich history and multifaceted purposes, the dam stands as a testament to the importance of sustainable infrastructure in the face of changing climate conditions and water resource challenges.

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.
