Fishing in Big Bend National Park

Big Bend is desert country, and the water here reflects that.

The Rio Grande cuts the park's southern boundary for roughly 118 miles, carving the three major canyons — Santa Elena, Mariscal, and Boquillas — before continuing downstream as the Rio Grande Wild and Scenic River.

Two tributaries, Tornillo Creek and Terlingua Creek, also run through the park, though the Rio Grande is the only water open to fishing.

The park holds about 40 fish species in total, but most are minnow-sized; what anglers are actually targeting are the catfish. Blue, channel, and flathead catfish are the species you'll find on the end of a line here.

Spring and fall are the practical seasons — summer temperatures in the Chihuahuan Desert make bank fishing a serious physical commitment, and the river fishes better when the heat backs off.

The Rio Grande is open year-round, so winter fishing is possible for those willing to deal with the remoteness. Access is almost entirely bank fishing from the U. S. side.

The river is not a put-in-and-motor situation; the canyons are roadless and reaching the water often means hiking. Rio Grande Village, near the eastern end of the park, is one of the more accessible stretches.

The permit setup here is different from anywhere else in Texas. A state fishing license is not required inside the park boundary, but you do need a free NPS fishing permit, available at any visitor center.

On the Rio Grande Wild and Scenic River outside the park, a Texas state license applies instead. Legal methods inside the park are pole and line, rod and reel, throw lines, and trot lines — jug lines are prohibited within park boundaries.

Chumming is also illegal. Certain springs and ponds are completely closed to fishing; the spring-fed pond near Rio Grande Village shelters the Big Bend Gambusia, a fish found nowhere else on earth, and it is off-limits entirely.

The Rio Grande has lost species here that won't come back — the American eel and Atlantic sturgeon both disappeared after upstream dams blocked their migration routes. What's left is worth protecting carefully.
