At Amistad, the fishing rules can change before the shoreline does

Amistad spreads across 64,900 acres of the Rio Grande near Del Rio. Largemouth bass are the main sport fish, while anglers often look for smallmouth bass in the Devils River arm. White bass, stripers, and catfish add other seasons to the lake.

The international line matters. Anyone fishing in Mexican water needs a Mexican fishing license, and TPWD says the requirement covers everyone in the boat. Use the live reservoir page for current boundary and license guidance before crossing.

The boat itself needs attention too. Zebra and quagga mussels are established here. Draining water is required by law, and moving the mussels is illegal. Clean, drain, and dry the boat, trailer, livewell, bait bucket, and gear before the next lake.
