Float fishing with a centerpin reel is the most effective method for presenting bait naturally in a river. The free-spinning spool lets current pull line off the reel at exactly the speed of the water, creating a drag-free drift that no other reel type can match. This guide covers how to set up a centerpin float rig from scratch — float selection, shot patterns, leader construction, and drift control — for steelhead, salmon, and river trout.

Float Selection

Centerpin floats are typically balsa or foam stick floats in sizes from 3 to 15 grams, with the size determined by water speed and depth. Faster, deeper water requires a larger float with more buoyancy to support the heavier shot pattern needed to reach and hold bottom. Slower, shallower water uses smaller floats with lighter shot for a more delicate presentation. The float should be sized so that the shot pattern sinks it to the point where only the painted tip and a small portion of the stem remain above water — this maximizes sensitivity by minimizing the resistance a fish feels when it takes the bait and pulls the float under.

Fixed floats attach to the line at a set depth using silicone sleeves or thread stops. They work well when fishing water up to the rod's length in depth (typically 10 to 13 feet for centerpin rods). Slip floats slide freely on the line and are stopped at the desired depth by a small knot or bead — they allow fishing depths that exceed the rod length because the float slides down to the shot pattern during casting and rises to the stop knot once in the water. For most steelhead and salmon rivers, fixed floats cover the productive water, but slip floats are necessary for deep pools and runs where fish hold below 12 feet.

Shot Patterns

The shot pattern controls how the bait sinks and at what speed it descends through the water column. The goal is a natural, progressive sink that mimics how a natural food item drifts and settles in current. Three basic patterns cover most situations.

A bulk-and-dropper pattern places the majority of the shot weight in a cluster 18 to 24 inches above the hook, with a single small dropper shot 6 to 8 inches above the hook. The bulk gets the bait down quickly, and the dropper provides fine-tuning for the last few inches of depth. This is the most common steelhead pattern because steelhead often hold near the bottom in moderate to heavy current, and the bulk weight gets the bait into the strike zone without the long delay of a gradually tapered pattern.

A shirt-button pattern distributes shot progressively from large near the float to small near the hook, with decreasing sizes at increasing intervals. This creates the most natural sink rate — the bait descends gradually rather than plummeting and then hovering. It is the preferred pattern for pressured fish and clear water where a sudden, aggressive bait entry spooks fish.

A bottom-bounce pattern uses a single large shot (or small pencil weight) at the bottom of the rig, positioned 12 to 18 inches above the hook. The weight bounces along the bottom while the bait trails behind it, elevated slightly above the substrate. This works in heavy current where lighter shot patterns cannot maintain bottom contact.

Leader and Terminal Tackle

The leader below the float is 6 to 10-pound fluorocarbon, typically 2 to 4 feet long depending on water clarity. In clear water, a longer, lighter leader (8-pound, 4 feet) reduces visibility and spook risk. In stained water, a shorter, heavier leader (10-pound, 2 feet) provides more control and abrasion resistance around structure. The hook is typically a size 4 to 8 octopus or egg hook, depending on bait type — smaller for single roe bags and worms, larger for clusters and skein.

Bait options for centerpin float fishing include cured salmon or steelhead roe (the most popular steelhead bait), wax worms, maggots, artificial beads (which mimic drifting eggs), and soft plastics like small worm imitations. Roe is typically tied in small mesh bags (spawn sacks) or fished as loose clusters held by a hook and a small piece of yarn. Beads are threaded onto the leader above the hook, held in place by a peg or toothpick, and fished to imitate a single egg drifting through the water column.

Drift Control

The centerpin drift is what makes this method so effective: the free-spinning spool lets the float travel at exactly the speed of the current, with zero drag from the reel. Your job is to manage the line between the rod tip and the float — keeping it straight (no bellies that create drag), slightly behind the float (feeding line downstream ahead of the float creates a downstream bow that pulls the float and kills the drift), and off the water surface as much as possible (line on the water catches microcurrents that create drag).

Rod height is the primary control. Hold the rod high (45 to 60 degrees) to lift line off the water and reduce surface drag. As the float drifts further downstream, lower the rod gradually to feed more line. At the end of the drift, the float should be directly downstream of your position with a straight line from rod tip to float. At this point, hold the drift (the bait swings upward in the current — sometimes triggering a strike at the hang-down point) for a few seconds, then reel in and cast again.
