If there’s one technique every serious Lake Lanier striper angler needs to know cold, it’s downlining. It’s not flashy. It’s not complicated. But done right, it’s the most consistently productive way to put stripers in the boat from late spring through the heart of summer and during the cold of the winter, when the fish are deep, the bait is stacked, and the thermocline is doing most of your work for you.
I’ve been running downlines on Lake Lanier for more than 30 years. This is what actually works.
This article is part of our complete Lake Lanier Striper Fishing Tips & Tactics guide — a season-by-season breakdown of how to read the lake and match your presentation to current conditions.
What is downlining?
Downlining means fishing multiple lines directly beneath the boat, each weighted to a specific depth. Unlike trolling, where you’re moving to cover water, downlining is a vertical, slow presentation. You position the boat over fish you’ve located on your sonar, drop your lines to the right depths, and let the live bait do the work.
It’s the go-to technique on Lanier for one simple reason: Lake Lanier stripers follow bait and oxygen levels, not structure. In summer, both compress into specific depth windows — and downlining lets you fish that window precisely, with multiple baits spread across the column at once.
When downlining works best on Lake Lanier
Downlining is most effective from late May through Mid September, when surface temperatures push into the upper 70s and stripers abandon the shallows for deeper, cooler water. You’ll typically find fish holding between 30 and 80 feet during this window, often suspending just above or within the thermocline.
It also works well in winter when fish are holding deep in the main channel — though winter presentations call for some adjustments I’ll cover below.
Spring and fall, when fish are shallower and more aggressive, other techniques like freelining and planer boards often outperform downlining. Knowing when to reach for which tool is half the battle.
The basic downline setup
Here’s the core rig I run:
Rod: A 7 to 7.5-foot medium-light to medium action rod. You want enough backbone to handle a big fish but enough sensitivity to read what the bait is doing. Longer rods give you better angle control when you have multiple lines in the water.
Reel: A quality line counter conventional reel with a smooth drag is non-negotiable. When a 20-pound striper decides to go, you need a drag that gives line evenly without burning off pressure. Cheap drags cost fish.
Main line: 15-20 pound monofilament or low-stretch braid in the 20-30 pound range. I prefer mono for downlining because the stretch acts as a shock absorber on the hookset and during the fight.
Leader: 5 to 6 feet of 12-pound fluorocarbon. Lake Lanier is very clear water. Fluorocarbon is nearly invisible underwater and will get you significantly more strikes than straight mono off the main line. This is not a step to skip.
Weight: 1 to 2 ounces, depending on depth and current.
Hook: A #2 – 1/0 octopus-style hook or octopus circle hook. Hook size should match your bait. Blueback herring running 4 to 6 inches need a hook that gives the bait room to swim naturally without killing it.

Reading your sonar before you drop a line
This is where most self-guided anglers leave fish behind. Before you drop anything in the water, spend time watching your graph. You’re looking for two things: where the bait is suspended, and where the stripers are sitting relative to that bait.
Stripers almost always position below or at the edge of a bait school. If you see a thick cloud of herring at 40 feet and arcs or marks just below at 50 to 60 feet, that’s your window. Set your downlines to bracket that zone — some lines above the fish at 45 feet, some right in the middle at 55, one or two deeper at 65.
If you’re marking fish but not getting bit, the depth adjustment is the first thing to make before you move the boat.
How to stagger your depths
Run multiple lines at different depths within your target zone. A typical four-rod spread on a summer day might look like this: front two lines at 55 and 45 feet, rear two lines at 65 and 50 feet. The goal is to cover the column in the area where fish are actually suspended.
Pay attention to which rod gets the first bite. That depth gets priority — slide the other rods toward it. If the 65-foot line fires twice in a row, the fish are telling you something. Listen to them.
Bait matters more than anything else
Dead bait will catch fish. Live bait will catch more fish. Lively blueback herring are the gold standard on Lanier in summer — they’re the primary forage fish and stripers have been eating them their whole lives. Pick the most active baitfish out of your well and hook them through the nose or just behind the dorsal fin. A herring that swims hard will cover depth on its own, creating a more natural presentation.
Check your bait every 5 to 10 minutes. A dead or listless herring sitting still at depth catches significantly less than a frisky one moving around. Cull weak bait from your well early.
Adjustments that make a difference
Line angle: In flat-calm conditions, your lines will hang nearly vertical. In wind or current, they’ll angle back. Angle is fine — it changes the presentation slightly but doesn’t hurt you. What you want to avoid is so much wind that your lines cross or tangle. Adjust boat position relative to wind to keep lines separated.
Boat position: In summer, I typically stay on spot-lock over a marked school rather than drifting. This lets me keep bait precisely in the strike zone without constantly adjusting weights.
Morning vs. midday: Early morning downlining often means shallower depths — 25 to 40 feet — as fish rise slightly to feed in lower light. By midday they push deeper. Check your graph and adjust accordingly rather than assuming the same depths from last week still apply.
A note on winter downlining
Winter downlining targets fish holding in the deeper main river or main creek channel, often 40 to 60 feet or more. The presentation slows down — less bait movement, smaller profile. Drop to 10 pound fluorocarbon leaders and slightly smaller hooks. Fish are cold, metabolism is slower, and they’ll follow a bait a long distance before committing. Patience matters more in winter than in summer.
The bottom line
Downlining isn’t complicated, but it rewards attention. The anglers who consistently catch fish aren’t doing anything magical — they’re watching their graph, matching their depth to where the fish actually are, fishing live bait that still has some life in it, and making small adjustments instead of big moves.
