21,620-acre North Indian River Lagoon section above Max Brewer Causeway with quality-assured NOAA BlueTopo and 2022 Indian River Lagoon topobathymetric contours, exact-polygon FWC fish evidence, mapped seagrass and verified public access. The water tops out around 23 ft. The depth chart is built from real agency bathymetry referenced to NAVD88; directly measured coverage remains distinguished from source interpolation. The channels, holes and drop-offs come from the source data, not a distance-from-shore model. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 21,666 acres, worked by 47.5 miles of shoreline, with 16 islands in the mix. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 10.5 mi long by 6.7 mi wide at the broadest reach. South Lake sits 9 mi southwest — the closest neighbouring chart.
In spring, spotted seatrout run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 4 to 15 ft, and winter fish settle into 5 to 20 ft. 2025 continuous seagrass edge is the standout, a seagrass edge at roughly 2 ft, rated prime for spring spotted seatrout. Time it for early morning. You won't need more than a popping cork + shrimp or a 1/4 oz jighead + paddletail (deep grass edge) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | 2025 continuous seagrass edge (2 ft) | Topwater walker, Suspending twitchbait |
| Summer | 4 to 15 ft | dawn | 2025 continuous seagrass edge (4 ft) | Popping cork + shrimp, 1/4 oz jighead + paddletail (deep grass edge) |
| Fall | 3 to 12 ft | dawn | 2025 continuous seagrass edge (3 ft) | Popping cork rig, Soft plastic jerkbait |
| Winter | 5 to 20 ft | midday & dusk | open water | Suspending twitchbait (long pauses), Scented plastic crawled on bottom |
Early season red drum (redfish) use the shallows, holding in 1 to 8 ft. Summer is a 2 to 12 ft game here, winter a 3 to 15 ft one. The chart's best answer is 2025 continuous seagrass edge — seagrass edge, 2 ft, prime for spring. Best bite is early morning and the evening. Tie on a weedless gold spoon or a paddletail swimbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | dawn & dusk | 2025 continuous seagrass edge (2 ft) | Gold weedless spoon, Paddletail on 1/4 oz jighead |
| Summer | 2 to 12 ft | dawn & dusk | 2025 continuous seagrass edge (2 ft) | Weedless gold spoon, Paddletail swimbait |
| Fall | 3 to 20 ft | dawn & midday | open water | 1/2 oz spoon (schools), Big paddletail |
| Winter | 3 to 15 ft | midday & dawn | open water | Scented soft plastic on 1/8 oz head, Slow-rolled paddletail |
Spring puts permit in skinny water — 3 to 23 ft is the zone. Summer fish stay in 2 to 23 ft, and winter fish hold in 6 to 23 ft. Spring permit concentrate at 2025 continuous seagrass edge, a prime-rated seagrass edge around 3 ft. Warm-month bites cluster around early morning and midday. A crab fly or a crab imitation covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 23 ft | dawn | 2025 continuous seagrass edge (3 ft) | Small crab fly, Shrimp-pattern jig |
| Summer | 2 to 23 ft | dawn & midday | 2025 continuous seagrass edge (2 ft) | Crab fly, Crab imitation |
| Fall | 3 to 23 ft | dawn | open water | Crab imitation, Shrimp-pattern jig |
| Winter | 6 to 23 ft | midday | open water | Crab imitation worked deep |
When the water first warms, snook slide up into 2 to 12 ft. Summer is a 3 to 15 ft game here, winter a 4 to 15 ft one. Start at 2025 continuous seagrass edge. It's a seagrass edge holding about 2 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a flair hawk jig (passes, night) or a big swimbait in the current rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
