If you follow our blog, you’ve seen our recent posts about how to choose fly fishing gear for a specific species. We’ve posted about how to choose the best fly rod for Bass here:

In our mission to provide our customers and readers with the most well-rounded information possible, we’ve decided to continue these species-centered posts, this time with fly lines.


Bass are one of the most popular gamefish across the US and beyond. These fish offer a challenging target to anglers who prefer boat fishing, river fishing for Smallmouth, or targeting fish in a tournament setting. Bass are ambush feeders and are generally fooled with a baitfish imitation although they eat crustaceans, bugs, and more. Because they’re found in temperate freshwater conditions, choose a freshwater fly line. Seems intuitive, right? 


As a reminder: Trident Fly Fishing is a full-service fly shop. We spend a lot of time testing gear and writing reviews to give you all of the tools to make your next trip a success.  We are not a blog or a review site. 100% of our funding comes from your gear purchases. So if this blog post helps you on your next fly fishing adventure, please buy your gear from us.


Fly Choice


Choosing a fly line for Bass often depends on fly choice. Here are a few quick tips:


  • Bass are most often found in shallow water environments with lots of structure. That means you're not often throwing sinking flies or sinking lines. A weight forward floating line is usually the best fly line for the job.
  • Bass are ambush feeders which usually means you're throwing larger flies. Large flies into tight cover = a fly line with a short front taper and a compact head designed for tucking large flies into tight structures accurately.
  • A large, lightweight fly thrown (think poppers) in windy environments necessitates a line (and a rod) that cuts through the wind... consider a line that's a half-size heavy or heavier (especially if you're fishing a fast action rod).


Some lines that fit the circumstances above are:



Fishing Deep Structure


Like any fish, Bass aren't only found in shallow water. Bass can also be found holding on deepwater drop-offs or around submerged structure that's not easy to reach without a sinking fly line. In these circumstances, choosing a fly line for deepwater Bass is a little different than choosing a fly line for shallow water Bass.

Choose a line that achieves the sink rate that you desire. If you're fishing structure that's 5-10 feet deep, an intermediate fly line may be the best line for the job. If you're fishing a 20-foot drop-off, a full sinking line may be a better bet. Here are a few recommendations.

River fishing for Smallmouth Bass and Largemouth is also different than casting to tight cover on a lake or throwing sinking lines. River fishing often necessitates a longer cast and a more delicate presentation. Smallmouth can also be caught using slightly smaller flies like a Wooly Bugger so a fly line with a really aggressive front taper or compact head isn't paramount. Other freshwater lines that are designed for Trout are probably your best bet in this scenario, especially if you're casting a rod that's medium-fast or moderate action. Some recommendations include:
