Summary

Completed in 1957, this earth dam stands at a height of 69 feet and serves primarily for irrigation purposes, with a storage capacity of 37,520 acre-feet. The dam also supports recreation and water supply needs in the region, covering a surface area of 1,090 acres.

Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Lake Weatherford Dam has undergone modifications in 1993 for structural enhancements. The dam's spillway, with a width of 2,250 feet, helps manage potential overflow events. Despite a moderate risk assessment, the dam's condition is deemed satisfactory, with regular inspections and a robust emergency action plan in place. This crucial infrastructure plays a key role in water resource management and climate resilience efforts in the area.

Enthusiasts of water resources and climate dynamics will find Lake Weatherford Dam's design and operational details intriguing. With its strategic location and significant role in irrigation and water supply, this earth dam on the Clear Fork Trinity River stands as a testament to effective water management practices in Texas. From its construction in the 1950s to its modern-day risk assessment and emergency preparedness measures, Lake Weatherford Dam continues to be a cornerstone of sustainable water resource management in the region, showcasing the intersection of human engineering and environmental stewardship.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
