Find Smallmouth as the Weather Warms in the Spring

Anglers across the state often associate spring with trout fishing season. Mountain streams are typically in prime flow conditions during this time of the year, and spring hatches have the fish feeding regularly. However, trout shouldn’t be the only fish on anglers’ minds during this time of the year.

Spring also coincides with great opportunities to target smallmouth bass as rivers across the state warm up from the winter months. Water temperatures warming is a thermal cue that triggers increased metabolism and activity of smallmouth bass, creating excellent fishing conditions across the state for bronzeback enthusiasts.

River Conditions and Smallmouth Biology  

On average years during late winter, water temperatures climb out of the 30s and into the 40s on rivers and streams across the state. As winter transitions to spring, water temperatures will continue to increase into the upper 40s and 50s. Smallmouth bass will react favorably to the warming trends and these fish will move out of the winter holes and into transitionary water in mid to late March. By late March, smallmouth can consistently be found holding in the middle of the water column behind mid-river boulders and along the edges of current seams where fast water meets slow water. These fish can also be found holding along ledges, drops offs, in riffles, and even along the banks.

Mid to late March signals the beginning of pre-spawn activity for smallmouth bass. Spawning typically begins in late April and continues all through the month of May on our Virginia rivers and streams. During pre-spawn, smallmouth can be very aggressive as they get territorial and put on weight for the spawning season. These fish actively ambush smaller forage fish and crayfish during this time of the year. Late March and April can provide for exciting fishing during the pre-spawn feeding frenzy.

Smallmouth bass are benthic spawners; males build nests in clean substrate including gravel, pebble, and cobble bottom. Males are cued to start this process when water temperatures climb into the 60s. These fish often seek out softer currents in 2 to 6 feet of water behind boulders, logs, or other obstructions when choosing spawning sites. Male smallmouth will dig a depression into the river bottom before spawning with a female.

After the spawn, males will stick around and guard their nests from aquatic and terrestrial predators. Spawning success is highly dependent on spring flows. High, muddy water from heavy spring rain events can impact smallmouth bass recruitment and spawning success. Because smallmouth are benthic spawners, high water in the spring time can wash beds out or cover them up with sediment, impacting recruitment and leading to variations in abundance of certain age classes within the population.

Spring can often coincide with high flows on rivers and streams across Virginia. Late winter snow melt and early spring rains can sometimes put rivers at flood level stages. Make sure to exercise caution during this time of the year and check the flows before you head to the river. In these high flows, smallmouth will orient to cover where they don’t have to fight super strong currents to find food. Even in high, muddy water, smallmouth are looking for meals and can be caught with a little persistence and determination as long as the river isn’t in flood stage.

Tactics and Techniques

It can be best to cover water when fishing for pre-spawn smallmouth bass. Floating the larger rivers during this time of the year is a great way to accomplish this, just remember to wear your personal flotation device. If you are wade-fishing smaller to medium-size rivers, don’t be afraid to do some hiking to cover ground on foot.

The pre-spawn bite is best approached by fishing subsurface minnow imitations in late March through April. Make sure to have some crankbaits on hand in a variety of colors during this time of the year. Rattling lipless crankbaits or noisy lipped crankbaits can be productive when the water is high and stained. The Rat-L-Trap causes commotion that attracts spring bass in these conditions. Soft plastic swimbaits like the Keitech Swing Impact Swimbait or Sassy Shads work well and sink deep quickly when fished on a jig head. Flashy spinnerbaits also entice strikes from spring smallmouth in stained water conditions.

When fly fishing our larger rivers, consider stripping streamers on a 250-grain full sinking line when the water is high and off color. The full sinking line gets your streamer down quickly when in heavy current. In average flows, you will be able to get away with a sink tip on our larger rivers and simply a floating line on our smaller to medium-sized rivers. The Half & Half is my favorite pattern to fish this time of the year. Chartreuse and white, tan and white, or olive and white are good color combinations. This bulky pattern pushes a lot of water and draws in strikes from big pre-spawn bass.

Clouser minnows and Chuck Kraft’s Kreelex are good “go-to patterns” during this time of the year. The flashy profile of the Kreelex does a great job of attracting smallmouth in high, stained flows. Doug Lane, local guide and owner of Angler’s Lane fly shop in Lynchburg, mentioned that “one can expect to catch some of the most aggressive fighting smallmouth during the pre-spawn weeks of March and early April.  Chuck Kraft once told me the key is to work one’s fly more slowly than one is accustomed to in the summer. This nugget from a wise fishing guide, the first full-time river smallmouth guide in Virginia, makes tremendous sense when you consider that the water is somewhat cooler, and the fish are often removing your presentation away from the area they are looking to spawn in.”

Also consider carrying large articulated streamers in your fly box during this time of the year. Remember, it pays to cover water during this time of the year, especially if you are floating. It’s important to target the right habitat, like mid-river boulders, ledges, drop-offs, or the tail-outs of mid-river islands, as you float downstream.

Topwater flies and lures will become more productive as summer approaches and April turns to May. Sometimes the bite can be tricky during the prime spawning month of May. During the spawn, smallmouth can sometimes refrain from eating actively. However, there are certainly fish to be caught in May as some smallmouth will spawn earlier than others. All in all, spring offers a welcome change from the slower fishing that occurs during the winter months. Strongly consider adding smallmouth to your list of favorite species to target as the trees bloom and the grass grows.
