Inland Trolling Basics for Beginners

Trolling is the art of dragging lures or bait behind a moving boat to cover water and find fish. It is the most efficient prospecting technique in open-water situations where fish are scattered across large areas. Rather than waiting for fish to come to you (as in anchored or bank fishing), trolling brings your presentation to the fish by systematically covering water until you find concentrations of active feeders.

Essential Equipment

A basic trolling setup requires a rod, reel, and appropriate lures. Trolling rods are typically seven to eight-and-a-half feet long with moderate or moderate-fast action — the flex absorbs the constant vibration of a trolling lure and provides a shock absorber when a fish strikes at speed. Line-counter reels are strongly recommended because they allow you to replicate successful line lengths precisely. Without a counter, you are guessing at the length of line deployed, which makes it nearly impossible to return to a productive setup after reeling in to check bait, clear weeds, or land a fish.

Boat speed is the most critical variable in trolling. Most freshwater trolling targets walleye, trout, salmon, or bass at speeds between one and three miles per hour. Within that range, speed determines which lures run correctly (each crankbait has an optimal speed range where its action is most lifelike), how deep lures run (slower speeds mean shallower running depths for most diving lures), and which species are most likely to strike (walleyes prefer slower presentations than salmon, which prefer faster ones). Use a GPS unit or trolling motor with a speed readout to maintain consistent speed — even half a mile per hour variation can change lure action and depth enough to affect catch rates.

Lure Selection and Depth Control

Crankbaits are the most popular trolling lures because they run at consistent depths determined by their lip size, line length, and boat speed. Each crankbait model has a published dive curve showing its running depth at various line lengths and speeds. Use these charts to select the right crankbait for your target depth — a number five Rapala Shad Rap runs about twelve feet deep at 100 feet of line at two miles per hour, while a number seven of the same lure runs eighteen feet. By choosing the right lure and deploying the correct line length (measured on your line counter), you place the bait precisely at the depth where fish are holding.

Planer boards, diving planers, and downriggers extend your trolling capabilities beyond what a crankbait alone can achieve. Planer boards clip onto the line and pull it to the side of the boat, spreading your trolling pattern wider and keeping lines out of the boat's wake. Diving planers pull lures deeper than their natural running depth, reaching fish in the twenty to forty-foot range that most crankbaits cannot reach on flat line. Downriggers use a heavy ball lowered on a cable to take lures to exact depths — the lure releases from the ball when a fish strikes, and you fight the fish on unencumbered line. Each of these tools adds complexity and cost but dramatically increases the water you can effectively cover.

Finding Fish While Trolling

Use your electronics (fish finder, depth sounder) continuously while trolling. Mark waypoints at every fish catch, every baitfish school, and every structural feature that looks promising. After a trolling session, review these waypoints on a map — patterns emerge that reveal where fish concentrate on specific structure types, depths, and contour features. Troll along contour lines (depth transitions where shallow water drops to deep) rather than randomly across open water. Fish concentrate along these edges because baitfish travel along contour breaks, and predators position themselves on the deeper side of the break to ambush prey moving along the edge.

Trolling Patterns and Strategy

Effective trolling follows structure rather than covering random open water. Contour trolling follows a specific depth line — holding the boat at a constant depth while following the natural curves of the shoreline, underwater point, or submerged reef. This keeps your lures in the strike zone (the depth range where fish are holding) for the maximum amount of time. Use your depth finder to maintain a consistent depth as the bottom contour curves and bends. S-turns (gentle weaving back and forth across the contour line) change lure speed and direction, triggering strikes from fish that ignored the straight-line pass — the outside lure speeds up and rises during the turn while the inside lure slows and drops, creating a speed and depth change that mimics fleeing baitfish.

Trolling speed experiments are essential for consistent success. Start at the standard speed for your target species (1.5 mph for walleye, 2.0 mph for trout, 2.5 mph for salmon) and adjust in half-mile-per-hour increments until you trigger strikes. On any given day, fish may prefer a speed significantly different from the textbook recommendation — water temperature, barometric pressure, and prey behavior all influence the retrieve speed that produces. When you catch a fish, note the exact GPS speed and replicate it for subsequent passes.

Managing Multiple Lines

Running multiple lines increases your chances by covering more water and presenting different lure options simultaneously. Start with two rods — one on each side of the boat — set at different line lengths and running at different depths. This two-rod approach covers a vertical range that identifies the productive depth faster than a single lure at one depth. As you develop confidence, add additional rods (regulations permitting) with planer boards to spread your pattern laterally, covering a trolling swath of fifty to a hundred feet rather than the six-foot width of a single boat.

Line management is critical with multiple rods. Stagger your line lengths so that if a fish takes one line and runs, it does not tangle with adjacent lines. Keep outside lines shorter than inside lines so that turning the boat does not cross lines. Use different colored line or different line-counter settings on each rod so you can identify which rod is hit and replicate its setup on the other rods.

Common Mistakes to Avoid

The most common trolling mistake is fishing too fast. Speed kills more trolling presentations than any other error — a crankbait designed to wobble enticingly at 1.8 mph becomes an erratic, unnatural blur at 2.5 mph. Use your GPS speed readout and resist the temptation to cover water faster than your lures run properly. The second most common mistake is ignoring your electronics. Many beginning trollers stare at the rod tips waiting for a bite while their depth finder shows no fish, no structure, and no baitfish beneath the boat. If the screen is blank, you are trolling over unproductive water — move to structure, find baitfish on the screen, and troll through those zones.

Line tangles from improper line management are the third common mistake. Stagger your line lengths, use planer boards to separate lines laterally, and make gentle turns rather than sharp ones that cross lines. When setting out multiple lines, deploy the inside (shortest) line first and the outside (longest) line last — this prevents the longer line from crossing over the shorter one during deployment. Reverse the order when reeling in: retrieve the outside line first, then the inside line.
