Summary
This private-owned earth dam stands at a height of 14 feet with a length of 1150 feet, offering a storage capacity of 106 acre-feet. Despite its modest size, the dam plays a crucial role in managing water resources in the region, with a normal storage capacity of 67 acre-feet and a maximum discharge rate of 2 cubic feet per second.
The dam's condition assessment in 2014 rated it as poor, indicating a need for maintenance and possibly rehabilitation to ensure its long-term reliability and safety. The inspection frequency is set at every two years, with the last inspection conducted in February 2017. While the hazard potential is not available, the risk assessment categorizes the dam's risk level as moderate. With the Texas Commission on Environmental Quality (TCEQ) overseeing state regulation, inspection, and enforcement, Williams Dam remains a critical infrastructure for water resource management and climate resilience in the area.
Water resource and climate enthusiasts will find Williams Dam as a fascinating example of how small-scale dams play a crucial role in local water management systems. It presents both the challenges of maintaining aging infrastructure and the opportunities for sustainable water use in the face of changing climate conditions. As efforts continue to assess and address the dam's condition and risk factors, its significance in ensuring water security for the community and ecosystem resilience in the region remains paramount.

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.
