This Indian River Lagoon fishing report covers mid-August, when the lagoon runs hot and the fishing compresses into a narrow morning window. Surface temperatures reach the high 80s by nine o’clock, and fish that feed on the shallow grass at sunrise slide to the deeper edges and channel drop-offs as the day builds. Speckled trout are the lead target. Plan around the new moon at the end of the week, which moves more water through the system than the lagoon sees in the two weeks before it.
What’s Hitting
Speckled trout are the most consistent target, feeding on the deeper grass and potholes at first light. Redfish hold along the spoil islands and mangrove shorelines and school up on the higher water. Black drum sit around the bridge pilings and the deeper docks, a good option once the trout bite fades.
Snook are in the residential canals and around the causeways, catch-and-release only. Juvenile tarpon and ladyfish roll in the deeper basins at sunrise, and mangrove snapper are on every piece of hard structure in the system.
Where to Find Them
The spoil islands along the Intracoastal from Melbourne south through Sebastian are the reliable redfish and trout water. The Wabasso, Melbourne and Eau Gallie causeways hold drum, snapper and snook.
Once the sun is up, move to the deeper grass edges in 4 to 6 feet near the channel for trout. Sebastian Inlet is worth a night pass for snook and the occasional tarpon on the strong tides.
Tides & Conditions
Expect lagoon water from 86 to 90 degrees. New-moon tides mean better flow through Sebastian Inlet and more movement in the lagoon proper, and the fish respond to it. Storms build by early afternoon most days, so fish the dawn window and plan to be off the water before the lightning. Water clarity is fair in the central lagoon and stained after rain; look for the cleaner edges, which is usually where you find the trout.
Tackle & Tactics
A 2500-size reel with 10- to 15-pound braid and 20- to 25-pound fluorocarbon covers the lagoon work.
- Trout: soft plastics on a quarter-ounce jighead are the most versatile presentation on the deeper grass; a topwater walker at first light is the fun version and still catches.
- Redfish: gold spoons and weedless plastics along the islands.
- Black drum: on the bridges, a piece of fresh dead shrimp on a knocker rig and 20-pound leader is all you need.
Local Intel This Week
Wabasso Causeway, the Sebastian Inlet ramp and the Eau Gallie ramp are the practical public launches: Sebastian Inlet for the night inlet pass, Wabasso and Eau Gallie for the causeways and spoil islands. Shore anglers can work the causeway catwalks after dark for drum, snapper and snook. Concentrate on the spoil islands, the causeways and the deeper grass edges rather than the shallow interior.
Snook harvest is closed on the Atlantic coast in mid-August, and redfish and trout rules vary by lagoon zone. Check current FWC and federal regulations and seasons before keeping fish.
This Week’s Tip
When the sun gets up, find the clean-water edge. In August the lagoon holds distinct bands of clearer and dirtier water, and the trout sit right on the seam. Idle along until you can see the grass again, then start casting; that line is worth more than any GPS number.
