Hey all i got invited yesterday to do some catfishing on the Guadalupe river, Believe it or not I've never done any river fishing before at least not for catfish. I normally use the old tried and true "fish finder" rig with a barrel swivel and egg sinker. I have to assume that there will some kind of current as well. Any info would be greatly appreciated, Thank you!

Id start there. if the current is really strong you'll keep getting hung up or it'll twist up real bad. Try starting at the end of the line...a sinker 15inches of lighter line to a swivel. At the top of the swivel tie a 8inch leader to a hook. Also at the top of the swivel tie your line to the reel.

What he said. That three way rig should work, I would suggest a very heavy weight depending on the current. If it's strong go with a 2-3 oz weight.

Fish the calm spots around sunken logs and such with live bream. That river is full of huge flatheads.

The only change I would make to your rig is to use a flat sinker rather than an egg sinker. That way it doesn't roll in the current. And use a heavier sinker if the current is strong.

Those pyramid weights are pretty good about not rolling in a current as well.
