Short answer: start with 8–12 colors (roughly 12–15 feet) for most mid-spring walleye trolling, and adjust up or down based on depth and structure. Think of leadcore length as a dial you turn to hit the depth where the fish are cruising. Each color is a marker for depth, and depth is the big driver when you’re trolling for walleye in spring.
Why this range works in mid-spring:
- Walleye often stack along weed edges, drop-offs, and channel banks in the 8–15+ foot zone as the water warms. Hitting that zone reliably gives you more bites without dragging bottom or pulling fish out of structure.
- Leadcore depth is predictable. Each color typically puts your bait at roughly 1–1.5 feet deeper than the previous color, depending on speed and lure weight. That makes 8–12 colors a practical setup for a common spring depth range, with small tweaks for your lake and speed.

Practical setup guide:
- Shallow/start: 4–6 colors (~4–9 ft). If you’re fishing bays or near shore in very clear, shallow water, this keeps baits in the strike zone without snagging.
- Mid-range: 8–12 colors (~12–15 ft). This is the workhorse range for spring, covering weed edges and mid-depth structure where fish frequently hold.
- Deep: 14–18 colors (~18–28 ft). When fish are deeper or you’re fishing channels, larger colorouts let you stay back and fish effectively.
How to dial it in on the water:
- Start with a neutral test: run two rods with different colorouts (e.g., 8 colors on one, 10 colors on the other) to learn where the bite window sits on that day and lake.
- Pair with moderate trolling speeds: about 1.8–2.5 mph is a good ballpark for many lakes; deeper colorouts will hold depth better at these speeds. If bites are light, try a touch slower to drop the bait a few inches; if you’re not getting depth, move up a color or two.
- Adjust by structure and clarity: cleaner, shallower water often means shallower colorouts; murkier water can push fish deeper or toward cover, so add a color or two.
- Keep it simple: bring a few colors-out options (e.g., 6, 10, and 14) and rotate them as the day unfolds. This minimizes guesswork and maximizes bite opportunities.
Gear note: use a quality leadcore line in the 18–36 lb range (depending on rod/reel capacity and target lure weight). You’ll find clear examples and setup details in leadcore-focused tutorials and product guides, such as Sufix Performance Lead Core Line and general leadcore guides like Lead Core Line: The WHAT, WHY & HOW.
Bottom line: 8–12 colors hits the core spring depth for most lakes, giving you a solid balance of depth control, bite windows, and gear compatibility. Start there, fine-tune with a second rod at a different color-out, and trust the fish to tell you when to adjust. Tight lines and may your baits find hungry eyes! 🐟💥
