Why Fly Fish For Bass?

We all know trout reign supreme when it comes to fly fishing, but bass fishing with a fly rod is starting to gain popularity and authority among fly fishers. Bass are the most sought after game fish in North America, and can be found virtually anywhere from rural streams to urban ponds. Bass are revered for their hard-hitting strikes and fighting ability, making them even more fun to catch on the fly. Smallmouth Bass

Habitat and Environment

Smallmouth and largemouth differ slightly in their habitats and environmental preferences; thus changing areas where fly fishers look. Both smallmouths and largemouths can be found in the same waterways, but certain conditions may be better for one or the other.

Habitats, Fly Fishing for Smallmouth Bass

Prime Bass Habitat
Bass love weedy shorelines
Smallmouth bass prefer colder water and less pollution. One thing that is important when fly fishing for smallies, is finding adequate cover. When searching for smallmouths in lakes pay attention to weed bed, drop offs, large boulders, submerged logs, and other underwater structure. Smallmouths also thrive in rivers and will tolerate faster currents than largemouths. This proclivity makes them easy to find, and will be in similar areas as trout. Focus attention on undercut banks, eddies, in front and behind boulders, and along seams and foam lines. Smallmouths need  higher levels of dissolved oxygen than largemouths, which is often why they are in deeper water, colder water, and fast moving waters (all generally have more oxygen). Their ideal temperatures are between 65-80 degrees Fahrenheit. Unlike trout, temperatures don’t play as big a role in their activity.

Habitats, Fly Fishing for Largemouth Bass

The ideal largemouth bass habitats consist of warm water, lots of cover, and shallow or slower waters. These robust fish can tolerate more polluted and murky water than smallmouths, and some of the waters are pretty surprising.
Largemouths prefer slow and murky water
Similar to smallmouth and all bass in general. You will want to focus your attention on cover. This could be weed beds, fallen trees, overhanging branches, and other rocky structures. They will generally stay close to shore making them easy to find when casting from a bank. One reason they tend to stay closer to shore is they require less dissolved oxygen than smallmouth and shallow, warmer  waters  do not produce the abundant amount of oxygen as deep cold water. When fly fishing for largemouths in rivers these same habitat principles apply. In addition, when fishing rivers pay attention to the current of the waters. These lazy predators like slow gentle currents. Within booth rivers and lakes, largemouths prefer water temperatures between 70 – 85 degrees, but can tolerate waters up to 90 degrees Fahrenheit!

Bass Behavior

Overview iconUnderstanding bass behaviors is crucial when fly fishing and the more knowledge one has the better angler they will become. First off, bass are predatory and opportunistic in their feeding habits. These behaviors make them less peculiar in what they eat, and makes things easier for the angler who doesn’t need to match the hatch necessarily. However, common sense applies, I.e. A bass isn’t going to eat a grasshopper in the winter or spring time, and it’s probably not best to be using a frog in months of hibernation. Furthermore, bass are smart and will prefer to expend less energy for a meal if they can. With that being said, they are instinctively more likely to strike a wounded prey. Using different retrieves can help mimic injured prey along with fly patterns. They will also prefer smaller meal because those are naturally easier to catch. Therefore, if you’re not getting much action with a particular fly, try downsizing instead of upsizing. Sometimes that smaller fly will be enough to peak the bass’ interest. Bass are known to be migratory based on the season and when they are spawning. But new studies seem to believe that bass have specific migratory patterns each day. They may follow paths or routes up to 3 times a day; similar to deer trails. In addition, bass are schooling fish, and will be found with others of their similar size. Usually bass will travel with 3-10 others. Large bass are seldom in schools, preferring solitude.

Bass Senses

Bass have some very keen senses primarily their sense of sight, taste, and movement. A bass’ sight is probably the most developed and useful sense when hunting, as it allows them to see fairly well even in murky water. Using flies with bright colors, especially red, can help grab their attention. However with this improved sight they don’t tend to be leader shy.
Smallmouth Bass
Bass hunt using their eye sight and lateral line (depicted above as white line running horizontal across fish)
They sense movement through their lateral line, probably the most used sense when feeding. The lateral line allows them to sense the slightest vibrations in the water and can spark curiosity, drawing them closer. Using flies with a lot of movement is advantageous when searching for bass. Lastly, their sense of taste is very important. It is said that bass have excellent taste and can even taste prey before they have it in their mouths. Whether or not this is true, it is safe to make sure your hands or free of any foreign smells when tying on your flies. Based on these senses and to put them in practical terms, using a brightly-colored, vibrating, and odorless fly will be the main factors to consider when choosing your flies.

Spawning Habits

Bass spawning season is broken down into 3 categories
  1. Pre-spawn
  2. Spawn
  3. Post spawn
Woman castingIn early spring or when water temperatures reach above 55 degrees will trigger males to move into shallow waters looking to create a nest. Because bass are so widespread this could occur anywhere between March and June depending on location. Most male bass reach sexual maturity between 3-4 years or when they reach at least 8 inches. Nests are constructed in water between 10-2 feet of water, (shallower for largemouths), and consist of clearing a gravel or sandy spot creating an indent in the ground. Once the waters warm to roughly 65 degrees females will also move into shallow waters to mate. Once the spawn occurs females retreat back to deeper waters, leaving the males to tend to and guard the fertilized eggs. After 1-2 weeks the eggs hatch into fry, with the males continuing to protect them for several more weeks. During this period the males are extremely aggressive and attack any potential predator. Most northern states have regulations to not fish until after the spawning season. Some say that catching bass during the spawn might cancel their instinct to spawn that year or even death. However, others say there is little damage to spawning bass, especially large females. If you’re legally fishing for bass during the spawn (most likely southern states) we encourage a quick and gentle release.

Bass Seasons

Depending on where you live the seasons will offer different fishing experiences and require different tactics. Here is a general overview of bass fishing by seasons.


Spring can be an exciting and fruitful time to fish. They are eager to eat and take in calories after the winter. They are not as picky during this time, but tend to focus on smaller hold over fish and crayfish. Crayfish patterns are probably the most effective during the spring. Once spawning occurs females will retreat to slightly deeper waters, leaving the males to tend the small fry on their own. Males will attack virtually anything but imitating predators of the fry such as small bait fish will be the most useful. Females are tired from spawning but very hungry. Using smaller patterns and slow retrieves will be helpful. About 2 weeks after bass spawn Shad, a popular food source of bass will spawn, causing a feeding frenzy. Look for disturbances in shallow water, indicating shad are being chased. There are a number of different fly patterns that match shad; such as grey and white deceivers or clouser minnows. Following the shad spawn, bluegills and other sunfish spawn creating more easy targets for bass. Use similar patterns for shad but introduce more vibrant colors to imitate these other fish species.


As the water warms and summer begins, food sources are prevalent and there isn’t anyone on specific food sources. Anything from smaller baitfish, crayfish and insects can be deadly for bass. Especially smallmouths will rise to the surface for a hopper or damselfly pattern. Summer also means exciting topwater fishing action to imitate frogs and mice. In rivers using simple bead head nymphs will also take bass. Smallies tend to retreat to deeper waters on really bright hot days. Putting on a sink tip line or sinking leader can be necessary to get your fly deep enough. On the other hand, the warm-water-loving largemouths will remain tucked up in shallow weed beds and underwater debris.


Fall can offer some great bass fishing
Once September hits and water temperatures begin to cool lake and river vegetation starts to die off creating more open pockets of water. Surface insects are abundant—using crickets, ants, grasshoppers, and beetle imitations will lure bass to the surface. Early fall generally offers better fishing in the mornings before petering out later in the day. Later in the fall, Shads become the primary food source again. Most of the insects have died off, and receding vegetation causes small baitfish to lose their hiding spots. Shads migrate into shallow water following their main food source, plankton. Many of the shads and other bait fish will die off once the temps drop below 40 degrees and dying shads make great meals for bass later in the fall. Use patterns with some red and slow disjointed retrieves to mimic these dying fish. Crayfish are still abundant and besides shad make up a majority of their diet before winter hits.


Depending on where you live bass fishing tends to slow down. In the northern states most of the lakes and rivers freeze over making angling impossible on a fly rig. In warmer states fishing will depend on what the water temperatures stay at. Most places will result in a decline of vegetation and other bait fish minimizing the amount of food. In addition, the cooler water temps slow the bass’ metabolism, causing less need to eat and slower movements overall. Crayfish are still plentiful during winter.

Best Time of Day and Conditions To Catch Bass

Timing can be key when fishing for bass. Different times, seasons, and weather conditions can affect fishing. It’s possible to catch bass at any time during the day. Although, for summer fishing it’s argued that dawn and dusk yield the best bass fishing. During bright and hot summer days smallmouths retreat to deeper water, but  they can still be caught; it just might require heavier streamers or sink-tip lines. Largemouths are not as peculiar when it comes to warm bright days, and will remain shallow ready to take surface flies. In the cooler months of spring and fall, mid-day fishing is a little better, as it gives time for the water to warm up and in turn, the fish start moving more. Like most fishing, overcast and rainy weather often produces more bass action. Windy conditions can also be productive as the water surface becomes more broken up with waves.

What Do Smallmouth and Largemouth Bass Eat?

Crayfish are a favorite for bass
One of the most important questions to ask when learning how to fly fish for bass. Bass are predatory fish and will eat a variety of creatures. Both largemouth and smallmouth bass eat similar foods, with smallies being more prone to eating insects. Another consideration, due to size, largemouths can handle bigger prey.

Some favorite foods for bass include

  • minnows
  • shad
  • small baitfish
  • leeches
  • crayfish
  • frogs
  • mice
  • insects
It’s important to understand what food sources are prevalent in the waterways you’re fishing. However, because bass are opportunistic, they will eagerly take a fly that does not represent any specific food source.

Best Fly Fishing Flies for Bass

Most bass flies will be either streamer flies or topwater flies. Bass will also take small nymphs in rivers and creeks, along with some surface insects such as mayflies, caddisflies, dragonflies/damselflies, and terrestrials. For topwater flies there are 3 main varieties that bass cannot resist which are
  • Poppers
  • Sliders
  • Divers
  • Deer Hair Frog PopperPoppers – Fly fishing poppers for bass can be incredibly effective. Poppers are a type of fly used to imitate surface creatures, primarily frogs and mice. Poppers can be made from foam, cork, hair, and wood.

These flies have a flat or slightly concave front that when stripped make a distinct “popping” sound that can be heard by nearby bass.

Poppers are best used in shallow waters especially among weeds and other structures. Some popular poppers are Boogle bugs, double barrel popper, and the peeper popper. Deer Hair Frog Popper

  • Dahlberg DiverDivers – Another topwater fly popular for bass are called divers. They are similar to poppers but their bullet shaped design allows them to dive under water before returning to the surface when stripped.

These movements look virtually identical to a frog diving underwater. Dahlberg Divers are the most well-known pattern and can entice ferocious strikes from big bass. Dahlberg Diver

  • Sneaky Pete SliderSliders – A hybrid between poppers and divers. Due to their cone shaped design, sliders submerge underwater when stripped, but not as extreme as a diver fly. One popular slider pattern is the Sneaky Pete, which represents frogs, and small baitfish. Sneaky Pete
  • Deer Hair MouseDeer Hair Mouse – This is one of the better known mouse patterns. The deer hair is helpful as it creates more noise and water movements, indicative of a struggling mouse. Cast this fly near banks with overhung trees near dusk or dawn. Deer Hair Mouse
  • Crayfish – As mentioned above bass love crayfish, and many times crayfish make up the majority of their diet. When fishing for bass and not sure what to tie on, start with a crayfish pattern. There are hundreds of crayfish patterns, and can be found in numerous styles, colors, and materials.

Some of our recommended patterns include: the skulldaddy crayfish, clouser crayfish, the near Nuff crayfish, and soft shell crayfish. Assorted Crayfish Flies

  • Game Changer FlyGame Changer – This is a type of articulated streamer with usually 3 segmented parts. Because of this design it creates “S” curve movements identical to small baitfish. The extra movements also push more water, signaling to bass that there is prey nearby. They can be tied in many different colors and sizes depending on the fish you’re wanting to imitate. Game Changer Fly
  • Wooly Bugger – an instant classic, this fly works wonders for trout, panfish and bass. It is very versatile and will mimic a leech, small minnow, and even crayfish. This fly is easy to tie and can be fished a variety of ways. Wooly Buggers
  • Bunny Leech FliesBunny Leech – The bunny leech is another tried and true fly that is also easy to tie. It can be made in a variety of colors but most traditionally black. They are a go-to summer fly, and the rabbit fur makes for realistic movements of a leech that bass can’t resist.  Bunny Leech
  • Clouser minnow – This simple yet effective streamer can be made with a few materials and can depict a number of different minnow species. Assorted Clouser Minnows
  • Hoppers –  Grasshoppers appear in Assorted Hopper Flieslate summer lasting around till fall. These insects are notorious for their poor flying ability and often end up in rivers, lakes, and ponds where they are easy meals for bass.

There are a variety of hopper patterns made from different materials. Assorted Hopper Flies

  • Dragonflies/damselflies – For bass, dragonflies and damselflies can mean a Dragonfly Fly Assortmentbig meal. These bugs are known for being expert flyers but will occasionally fall into the water where a hungry bass can pick them off. There are several different types of dragonfly patterns. Assorted Dragonfly/damselfies

Bass Fly Fishing Gear

Most anglers fishing for bass can get away with conventional trout fishing gear. However, if you’re wanting to get more serious about fly fishing for bass there are a few considerations when picking out gear.

Bass Fly Fishing Rods

Fly rods iconWhen finding what rod you should use for bass, there are few things to keep in mind. The first is the weight of the rod. This can be determined by a few different factors: the size of flies you’ll be casting, and size of water you’re fishing, and size of the fish you’re chasing. If you’re going to be fishing smaller rivers and creeks with mostly nymphs and small streamers a 5-6 weight rod should be fine. On larger rivers that require longer casts with bigger flies, having something with a little more heft like a 6 or 7 weight will make things much easier. Lastly, the weight of the rod depends on the weight of fish you’re targeting. If you’re intentionally searching for trophy largemouths, having a bigger rod is necessary. The length of the rod is another consideration, and depends largely on where you’ll be fishing. A shorter rod is more effective when fishing in tight quarters or casting among trees and under branches. A rod with a little more length is suitable for wide open rivers and lakes as it helps for more accurate and longer casts.

Bass Fly Fishing Reels

When it comes to bass reels, having something lightweight with a good drag system. Because of how strong bass fights, they’ll often be pulling lines off your reel. You’ll want a reel with a solid drag system that can be adjusted depending on the size of the fish. Large arbor reels are also preferred and very important. Large arbor reels allow for maximum line pickup and speed.

Bass Fly Fishing Line

When it comes to lines when fly fishing for bass a typical weight forward line will do the trick. However, when fishing for smallmouths during the summer in deeper water, having a sink tip line or sinking leader will be necessary to get your fly down deep enough.
