It also contains many oyster bars, grass lines, and deep holes, as well as downed trees that provide structure for fish to hang around.
With the open end of the lagoon facing Fripp Inlet, boaters have easy access with the Russ Point boat landing less than a mile away. Once in the lagoon, a few key areas offer anglers good opportunities to boat all of the inshore big three.
The pedestrian bridge, close to the mouth of the lagoon, offers shade and structure and is within casting distance of grass lines and oyster bars, and it offers various water depths. Mud minnows will catch all three of the inshore slam species.
The next hotspot is within 100 yards of the pedestrian bridge and occurs at low tide. In this spot, a sandbar covers about 95 percent of the lagoon's width at dead low tide, leaving a very narrow, deep hole. Any fish moving in and out of the lagoon must pass through this narrow body of water.
"It's the first place I target at low tide," said Lady's Island's John Long, who has caught flounder, trout and reds from this area. "It's a good place to get out of the boat, stretch your legs, and catch the inshore slam."
A third spot for anglers to key on is the "dogleg" of the lagoon. About 100 yards from the big sandbar, the lagoon makes a 90-degree turn to the left, then quickly turns back 90 degrees to the right after about 40 yards. A large, barnacle-encrusted oak tree lies half-sunken in the dogleg, and several half-submerged palmetto trees are present as well. A line of grass covers the left bank of this spot, with oyster bars all around.
It's a challenging spot due to all the obstacles that a hooked fish can use as refuge, but the obstacles are also one reason so many fish gather in this spot.
Mud minnows and shrimp presented under a popping cork or on the bottom will catch redfish and trout, and fiddler crabs are a favorite food of redfish. Flounder won't pass up a free meal slowly dragged over the bottom, but mud minnows are an angler's best bet for hooking these flat fish. Artificial baits like DOA shrimp and paddletail grubs are also good choices.
The lagoon is a great place to catch black drum, sheepshead, spot, and whiting.
