Designed by J M Jowers, this earth dam stands at a height of 60 feet and spans a length of 612 feet, with a maximum storage capacity of 10,350 acre-feet. With a normal storage capacity of 7,590 acre-feet, the dam plays a crucial role in supporting agricultural activities in the region.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Upper Nueces Lake Dam undergoes regular inspections with an inspection frequency of 5 years. The dam features various outlet gates including other controlled, slide (sluice gate), and uncontrolled gates. Despite some modifications in 1990, the dam's hazard potential is not available, and its condition assessment is currently unrated.
While the dam's risk assessment and management measures are not specified, its emergency action plan (EAP) was last revised in 2010. With a spillway width of 280 feet and a maximum discharge capacity of 3,648 cubic feet per second, Upper Nueces Lake Dam stands as a crucial infrastructure for water resource management and climate resilience in Zavala County, Texas.
