Amistad is one of those lakes where the combination of factors -- international border reservoir, clear warm water, rocky canyon structure -- produces fishing that surprises people the first time they see it. The largemouth bass fishery is genuinely world-class. The Devils River arm holds excellent smallmouth. The striped bass bite adds variety. 65,000 acres of the Rio Grande on the Texas-Mexico border with Del Rio 12 miles away. Just remember: crossing to the Mexico side of the border buoys requires a Mexican fishing license for everyone in the boat.

The bite is most consistent when anglers focus on proven techniques and presentations. Live bait and standard lures continue to produce results in October, with success often depending on targeting the right depths and structures where fish are holding this month.

Lake Amistad Largemouth Bass Fishing Report
Largemouth bass at Lake Amistad are the primary draw for anglers who travel specifically to fish the reservoir. The combination of clear water, warm temperatures extending the growing season, and abundant rocky limestone structure produces large fish throughout the lake. The lake is consistently ranked among the top largemouth bass fisheries in Texas and the world. TPWD regulation: 14-inch minimum, 5-fish combined daily bag limit for all black bass. Verify current regulations at tpwd.texas.gov. Spring is the primary season, with prespawn fish staging on rocky main-lake points and submerged channel edges in March before moving into the protected coves and canyon pockets to spawn in April and May. The clear water at Amistad makes sight fishing during the spawn a genuine option when conditions align. Summer bass relate to the deeper rocky structure and the shade of submerged canyon walls in 15 to 25 feet. Crankbaits and drop shots worked along rocky transitions produce fish year-round. Fall crankbait and topwater fishing on the main-lake points and creek arm mouths produces actively feeding largemouth through November.
Lake Amistad Smallmouth Bass Fishing Report
Smallmouth bass at Lake Amistad concentrate primarily in the Devils River arm of the reservoir, where cooler temperatures, current influence, and rocky canyon structure create ideal smallmouth habitat. The Devils River arm is considered one of the better smallmouth fisheries in southwest Texas. TPWD regulation: 14-inch minimum, 5-fish combined daily bag limit with all black bass. Verify current regulations at tpwd.texas.gov. Tube jigs, drop shots, and small crankbaits worked along the rocky canyon walls and submerged point transitions of the Devils River arm in 5 to 20 feet produce consistent smallmouth. Spring smallmouth fishing peaks in March and April as fish move to gravel and rock spawning areas adjacent to the deeper canyon structure. The rocky sections of the main lake near the Devils River confluence also hold smallmouth mixed with largemouth. Fall is productive as smallmouth move shallower to feed aggressively ahead of winter.

Striped bass at Lake Amistad are maintained by a TPWD stocking program and provide an additional sport fish target throughout the main lake basin. Striped bass do not reproduce naturally in the reservoir. TPWD regulation: 18-inch minimum, 5-fish combined daily limit with hybrid striped bass. Verify current regulations at tpwd.texas.gov. Striped bass at Amistad follow shad schools throughout the main lake and the deeper open-water areas. Trolling deep-diving crankbaits and umbrella rigs in 20 to 35 feet along the main channel produces stripers, particularly during the warmer months when fish hold in the thermocline. Surface feeding activity in fall when stripers push shad to the surface provides the most exciting striped bass fishing of the year.
Lake Amistad White Bass Fishing Report

TPWD regulation: 12-inch minimum, 25-fish combined daily limit with blue catfish (maximum 10 fish 20 inches or longer). Verify current regulations at tpwd.texas.gov. Cut shad, chicken liver, and prepared catfish baits fished on the bottom near the main channel transitions and tributary mouths produce consistent channel catfish. Summer night fishing from NPS public access areas around the lake is the primary catfish approach. The Rio Grande inflow area concentrates catfish during spring high-water periods.

Summer night fishing in the main Rio Grande channel with stout tackle produces blue catfish in the 10 to 30-pound range.
If you haven't replaced your braided line in a season or two, now's the time. Braid holds up better than mono, but abrasion from wood and rock adds up. Reaction Tackle is one of my favorite places to order from.

About Lake Amistad
Lake Amistad (Amistad Reservoir) is the international reservoir on the Texas-Mexico border that has built a reputation as one of the world's premier largemouth bass fisheries. The International Boundary and Water Commission completed Amistad Dam on the Rio Grande in 1969, creating 65,000 acres of clear, warm reservoir water fed by the Rio Grande and the Devils River. Val Verde County, Texas, is the only US county on the reservoir. The National Park Service manages Amistad National Recreation Area on the US side. The Devils River arm adds exceptional smallmouth bass habitat to a lake already known for trophy largemouth.
International border regulations. The US-Mexico international border on Amistad is marked by numbered buoys (RG1 through RG28) following the historic Rio Grande channel. Texas (TPWD) regulations and a valid Texas fishing license apply on the US side. On the Mexico side of the border buoys, all persons in the boat must hold a valid Mexican fishing license, and Mexican fishing regulations apply. The limits differ between the two countries. Verify current Texas regulations at tpwd.texas.gov and obtain a Mexican fishing license if planning to fish the Mexico side.
Devils River arm. The Devils River enters Amistad from the north and creates a distinctly different arm of the reservoir with cooler temperatures, cleaner water, and rocky canyon structure that supports excellent smallmouth bass. Anglers targeting smallmouth specifically should focus efforts in the Devils River arm, particularly in spring and fall when fish are most active in shallower structure.
Lake size and access. Lake Amistad covers approximately 65,000 acres at conservation pool on the Texas-Mexico border in Val Verde County, Texas. Del Rio, Texas (population approximately 35,000) is the primary gateway approximately 12 miles southeast of the dam. US Highway 90 connects Del Rio to the lake. The NPS Amistad National Recreation Area provides boat ramps and public access on the US side. Entrance fees may apply at NPS facilities.
