Summary
Completed in 1971, this earth dam stands at a height of 24 feet and spans a length of 800 feet, providing a storage capacity of 210 acre-feet. Situated on Hackberry Creek, the dam serves as a critical resource for water management in the region.
Despite its important role in the local water supply, Williams Lake Dam does not have a spillway and is not regulated by the state. The dam's hazard potential is labeled as "Not Available," indicating a lack of recent assessment. With a risk assessment rating of "High (2)," there is a need for ongoing monitoring and maintenance to ensure the safety and integrity of the structure. Additionally, the dam lacks an Emergency Action Plan (EAP) and may benefit from the development of such guidelines to address potential risks and emergencies.
In the context of increasing climate variability and water resource challenges, Williams Lake Dam serves as a vital asset for the community. As enthusiasts in water resource and climate management, it is imperative to advocate for the proper maintenance and regulation of such structures to safeguard against potential hazards and ensure sustainable water management practices for future generations.

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.
