Summary

Completed in 1958, this earth dam stands at a height of 81 feet and spans a length of 5980 feet, creating a reservoir with a maximum storage capacity of 531,000 acre-feet. The dam is situated on the Nueces River and is regulated by the Texas Commission on Environmental Quality (TCEQ).

With a surface area of 44,100 acres and a drainage area of 16,656 square miles, Wesley E Seale Dam plays a crucial role in managing water flow and providing flood control for the region. The dam features a controlled spillway, outlet gates, and other controlled mechanisms to ensure the safety and efficiency of its operations. Regular inspections and maintenance have deemed the dam to be in satisfactory condition, with a low hazard potential and a high level of risk management measures in place.

As a key infrastructure for water management and recreation, Wesley E Seale Dam continues to be a significant asset to the community, offering not only essential water supply but also opportunities for outdoor activities and enjoyment. With a strong foundation and proactive risk assessment and management practices, the dam stands as a reliable and resilient structure in the face of changing climate conditions and water resource challenges.

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.
