4. The three fly lines you need for bass fishing. (4 of 18)

For a lot of bass fisheries, you probably only need one fly line. And, the go-to line for the most part is an intermediate line. An intermediate line is a slow sinking line and you could fish shallow with it, just fish with an unweighted fly. And, you could also fish deep with it. If you put a weighted fly on it'll pull the intermediate weight line down and you could fish it deep, so that's really a go-to line.
But if you're going to be fishing a big lake like this, you're probably going to want two or maybe three fly lines. I never go without a floating line because I love fishing poppers for bass. If there's any opportunity, I'm going to fish a popper so you need a floating line for that. And then, if you're in a big lake, particularly if it's mid-summer and you suspect the bass are suspended deep.
You're probably also going to want a full-sinking line or a depth charged line. So three lines are great, probably two is a good idea on large lakes.
