How to Fish Offshore for Bass: Deep Water Masterclass

Offshore bass fishing is a strategy a lot of anglers struggle to learn — but it’s truly necessary if you want to catch bass year-round. No matter where you live, from Idaho to Alabama, Connecticut to California, fish eventually move off the docks, the shallow grass, and the shallow sticks to live their lives offshore. In this masterclass I’m going to give you everything: why bass go deep, how to read your electronics and maps, and how to find and catch them in the three places they live offshore — grass, rock, and wood.

If bass have so many shallow places to live — docks, lily pads, grass, stumps — why would they ever leave? Because that’s where the entire ecosystem moves when water temperatures get too extreme, hot or cold. When the forage base — bluegill, crawfish, shad, baitfish — pulls off the bank, the majority of the bass follow. They live where the food is. So if you’re running the bank in summer or winter throwing everything you normally catch fish on and can’t buy a bite, it’s probably because the fish aren’t even there.

Deep can feel intimidating — how deep is offshore? 50 feet? 100? To me, offshore is anything from 10 to 30 feet, with my most consistent bites coming from structure and cover in 10 to 20 feet. Looked at that way, it’s not so daunting.

A few pieces of gear make offshore fishing far more efficient. First, two fish finders connected by Ethernet or Wi-Fi, so you can share waypoints from one graph to the other. Second, a marker buoy — especially if you don’t have forward-facing sonar. Units like Garmin LiveScope, Humminbird MEGA Live, and Lowrance ActiveTarget have radically changed how anglers fish offshore. It’s expensive technology, but if you can save up — even over a year or two — forward-facing sonar basically eliminates the need for a marker buoy and makes you a dramatically better offshore angler.

Reading a Topographic Map

Mapping is step one. A topographic map shows the contours of what’s down there — imagine a mountain range, but underwater. Almost no lake is a smooth bowl; every one has points, humps, and channels. The main theme is looking for differentiation in the contour-line pattern. Here are the features that hold offshore bass:

The Four Types of Sonar (in Order of Importance)

Side scan is number one for finding offshore bass. It shows what’s to the left and right of the boat as you idle forward; the most recent scan is at the top of the screen and history scrolls down. Objects cast a shadow — just like a flashlight can’t light the back of an object — and the longer the shadow, the taller the object. Hard structure (wood, rock, grass roots) returns a hard white; soft bottom returns darker.

Downscan shows what’s directly under the boat — great for spinning back over something you marked on side scan to confirm it. Traditional 2D sonar reads similarly but, in my opinion, makes far too many things look like fish (brush, grass, and random sticks all show as arches) — I only use it in select situations. And forward-facing sonar lets you drop the trolling motor and see exactly what you marked in seconds. For offshore work, my graphing is mostly side scan, mapping, and forward-facing sonar — I rarely lean on downscan or 2D.

Grass grows in three places: on the bank (most of it — often emergent, so you can find it with your eyes), offshore but connected to the bank (follow the shallow grass out deeper and deeper until you reach 5 to 15 feet), and offshore and disconnected (out in the middle on humps and underwater structure, findable only with your maps and electronics). Most offshore grass fishing happens in a fairly shallow 5 to 10 feet — hydrilla can grow past 25 feet on some lakes, but that’s not the norm.

On the map I start where I always start — points — then work grass edges (grass lines). Fish love edges; nine to ninety-nine times out of a hundred I’d rather fish the edge than the open water beyond it or the thicker grass inside it. Grass edges are rarely a clean line — the grass just thins and scatters. The real key word is irregularities: a little point, indentation, or hole in the grass is where the bass sit. On side scan, grass looks like a stringy cloud; for this shallow work I drop my frequency (down to ~455 kHz for clarity at short range) and tighten my side-scan range to about 40 to 50 feet.

Grass Baits

If you don’t know exactly where the fish are, start with a moving/reaction bait to cover water — my two favorites offshore are the lipless crankbait (great pre-spawn and fall) and the vibrating jig (tough to beat spawn through summer; the trusty Thunder Cricket is a staple). Fish actually react when you rip a treble bait free of the grass, and getting momentarily snagged even tells you whether the grass is healthy — and bass strongly prefer healthy, green, oxygen-producing grass (like fresh coontail) over brown, dying grass.

Once you know where the fish are, slow down with a worm. My four go-tos: an all-purpose swimming worm (the Strike King Cutter Worm — Texas-rig it deep or shallow, hop or swim it), a big ribbon-tail worm (Rage Anaconda) for deeper, hotter summer grass, and a slightly upsized drop shot — which shines when fish sit a foot or two above the grass, keeping the worm wiggling right in their face instead of sinking down into the salad. For the full breakdown on the big-worm game, see my giant worm masterclass, and for the finesse presentation, my drop shot masterclass. If you want to go deeper on grass in general, my ultimate guide to fishing grass covers it all.

Bass live near rock because the forage base — especially crawfish — moves to offshore rock when temperatures hit their extremes. Unlike brush (man-made) or grass (needs oxygen to grow), rock is naturally occurring and can sit at any depth, but the best offshore rock is 10 to 30 feet. Three topographic areas to target: humps (a hill under water — like a rocky mountain, the bottom is often soil and the rock increases toward the top), points (rock on the land side usually continues underwater — but check your map, since underwater points often kick off at odd angles), and spines (a ridge between two deeper areas — the perfect blend of hump and point, often with the best rock, especially where it slopes fast).

For rock I run side scan, mapping, and traditional 2D together — 2D earns its keep here because a fish-sized rock and an actual fish look nearly identical on side scan (both hard white circular returns), so 2D lets me confirm whether a fish is sitting on the pile. I keep my side-scan range around 80 feet for detail, and I like color palettes like orange crawfish, black emerald, or inverse grayscale for picking out hard structure.

Bait-wise, I hardly ever lead with a moving bait on rock — I prefer bottom-contact lures because it’s like target casting to structure I can see. My two favorites are a football jig and a drop shot. If the rock area is massive with no defining boulders, I’ll pick up a moving bait — a soft-plastic swimbait on an Outkast Tackle jighead, a deep-diving crankbait, or an underspin — but most of the time I’m targeting individual rocks and tiny clusters that hold one to five fish.

There are many kinds of offshore wood — standing timber, cane piles, brush piles, laydowns — but the two that matter most offshore are the brush pile and the laydown. Since most brush piles are man-made (trees bundled with wire and sunk with cinder blocks), look where a person would put one: points first, then humps, then breaks (a fast drop usually means hard bottom like rock or clay), and finally flats — especially a flat near docks close to deep water, where dock owners or anglers have almost certainly sunk brush.

How you graph each shape matters. On a point, I idle a straight line in 10 to 20 feet before the point starts, run to the tip, loop through open water, and come back down the other side. On a hump, I take three straight passes to form a triangle — the fish usually aren’t dead-center on top, they’re near the break line. On a break, I zigzag shallow-to-deep down the drop. And on a flat, I put the pedal down and graph as fast as my transducer allows — forget quality, just find the pieces, mark them, and come back to inspect with downscan or forward-facing sonar.

Wood Baits — Weedless First

Conventional wisdom says throw a reaction bait first, but brush piles are so snaggy that I flip the order. I reach first for my confidence lures that won’t get stuck — a big worm on a shaky head and a football jig — and I catch the majority of my brush-pile bass on those two. Only after do I bring in the deep-diving crankbait (a 5, 6, or 8XD) or a sinking jerkbait to nab reaction fish. The logic: if you fire a treble bait in first and snag on cast one, you have to troll over and yank it free, spooking every fish in the pile. Give a pile 10 to 15 minutes of good weedless casts; no bite, move to the next one.

Final Thoughts

Offshore fishing seems daunting at the start — “I don’t even know what I’m looking for out here.” But once you understand your electronics and maps, you can pinpoint areas off the bank with real confidence. Learn your topographic map, master side scan, target the 10-to-20-foot zone, and hunt the three offshore homes: grass, rock, and wood. Find the irregularities, keep your bait in the strike zone, and mark your waypoints. The fish left the bank for a reason — go out there and follow them.
