Mid-spring walleyes are on the move as water temps creep up, so your best bet is to read the screen for subtle but tells-you-quick signs rather than waiting for a big, obvious target. Here’s a practical, field-ready approach to identifying walleye on sonar and side imaging, with tips you can apply on your next trip:
-
Start with 2D sonar arches near structure
- Walleyes often show as slender arches or tight, compact targets close to the bottom or along ledges. If you’re seeing small, sharp arches hugging a drop-off or shoreline edge, that can be a solid sign of walleye with a light to moderate jig or minnow presentation. Use the arch as a trigger to drop your lure into that zone and test for bites.

-
Watch for suspended targets around bait schools
- Walleye often herd bait and move just off the bottom. If you see a blob of bait with smaller marks stacked around it in the water column, it’s a strong sign they’re in the area. If you’ve got Side Imaging, you’ll notice fish silhouettes that aren’t hugging the bottom.

-
Look for patterns along ledges and weed edges
- In spring, walleyes chase bait along the edge of structure—drops, points, and weedlines. On sonar, that shows as a line of arches or scattered targets moving along a depth change rather than a single large school on the bottom. When you spot that pattern, work your jigging cadence across the depth change to test bites. For a quick reference on how sonar visuals relate to real fish, see [All About Walleye] (All About Walleye - (In just 7 MINUTES)) and the general sonar-reading guides linked above.
-
Use proper sonar settings to separate fish from structure
- Increase sensitivity enough to see faint fish without turning the screen into noise. Turn on depth range and bottom lock to keep the bottom clearly defined, then observe when new targets appear as you raise or lower your lure. If you’re unsure what you’re seeing, refer to basic interpretations in beginner sonar videos: What walleyes actually look like on Side Imaging and How to read fish finder sonar.
-
Quick action plan when you locate signs
- If you find arches near a drop or edge, drop a light jig (1/16 to 1/8 oz) or a live minnow under a small jig and vertical jig with a slow, steady cadence. If bites don’t come after a couple of drops, inch the lure deeper or shallower along the edge and test different speeds. In spring, small changes in depth and cadence often trigger strikes when the fish are chasing bait.
Seasonal reminder: mid-spring can bring shifting fish holds as spawning windows close and post-spawn fish relocate. Stay patient, adjust depths with the sun angle, and trust the sonar to show you where the active pockets are. Tight lines and steady pressure welcome those first walleye bites of the season! 🐟🎣
