Snook stack up and feed on baitfish along sharp inlet drops.

If you bottom fish offshore, you know about ledges. Ledges are golden if you are a snapper or grouper fan. Simply defined, a ledge is a distinct and abrupt rise of rock in otherwise sandy bottom. Some are only a foot high, some are five or more. Bottom veterans mark em on their bottom machines, and guard those coordinates.

Knowledgeable inshore fishermen have long scored on ledges as well. A patch reef dropoff in a shallow sound may hold bait and Spanish mackerel, for example. A shell bar ledge in the Intracoastal Waterway (ICW) can produce everything from flounder to redfish to snook to striped bass and bluefish. But often there are small, overlooked, fish-filled ledges that many inshore anglers fail to notice.

Stuart, Florida angler Sam Heaton and I had a pretty good morning recently working some Indian River flats for snook, small tarpon and seatrout. But as the August sun rose in the sky, the temperature soared and the shallow bite stopped, so Heaton decided to change tactics.

“With this strong falling tide, I’ve got something a little different in mind,” he said, and we ran his skiff to Jupiter Inlet. “Tide’s running perfect for drifting the ledge along this bank. Snook have been stacked up along this ledge for weeks now,” he added. We alternated between freelining live sardines and bumping plastic-tail jigs. Meanwhile, Heaton kept the boat right on the ledge by monitoring his depthfinder and nudging the boat from time to time with his bow and stern-mount electric motors. The shallow side of the ledge was eight feet and the deep side was about 20. The depthfinder clearly marked fish holding tight to the ledge dropoff, which were likely snook.

Man-Made Ledges Ledges also are clearly evident on most inshore charts, and sometimes on aerial photographs. Channel and range markers can lead the way to great ledge fishing action. Inlet and rivermouth jetties, as well as standard riprap banks, can have superb ledge fishing opportunities nearby. Bridges and causeways also create ledges—bridge abutments alter tide and current flow, which build fish-attracting ledges. The mouths of feeder creeks in tidal rivers usually have small ledges that harbor fish, particularly during falling tides.

We hadn’t fished 10 minutes when my deep live bait got nervous, and I felt a solid thump. I waited a moment for the fish to run, and then set the hook. A bulldog run from the ledge to deeper water was signature snook. I pressured the linesider, and worked it close near the boat, where it lunged away again, pulling drag. Once boatside, Heaton grabbed it by its lower jaw, hauling the 24-pounder aboard. Minutes later he positioned the boat atop the ledge, and over two hours we hooked nearly two dozen snook, including one pushing 30 pounds, and many weighing 12 to 20 pounds. Every fish was caught smack on that inlet ledge.

That is only one example of ledge productivity. Wade fishermen are acutely aware of how fishy even the slightest dropoff can be. A 6-inch to 1-foot dropoff is a ledge, and a real fish magnet on an otherwise shallow, flat expanse of bottom. A wader can “feel” a slight dropoff of only a few inches, which often holds feeding gamefish. Casts made parallel to a slight ledge are often most productive because a lure is in the “strike zone” through an entire retrieve.

Last summer while wading near Dauphin Island, Alabama with friends Jake Markris and Scott Heggeman, we hit a banner seatrout spot along such a flats ledge. We were casting plugs, jigs and live baits for trout and redfish, when Scott suddenly tallied three good trout in as many casts. Jake and I quickly waded toward Scott, and found he had located a sandy 2-foot ledge along the Gulfside beach of Dauphin Island, and trout were waiting with open mouths.

Bull redfish, inset, are among ledge-huggers that patrol channel edges.

Such slight inshore ledges are especially productive when current is running strong across them, from the shallow side to the deeper side. Flounder, redfish, black drum, seatrout, ladyfish, snook, tarpon, sheepshead and other species concentrate on the deep side of a ledge, watching and waiting for vulnerable baitfish, crabs and other goodies swept over the drop. Some sand or mud ledges like this can have small key spots for productive fishing. These ledge hotspots may be clusters of oysters or clams, rocks, boulders, weedbeds or pilings. Anything “different” along an inshore ledge can be a major fish magnet. Such things attract bait best, and so are usually the best locations for gamefish.
