13,421-acre South-Central Inshore Biscayne Bay section with quality-assured NOAA contours, NPS-documented target fish, mapped seagrass and oyster habitat, charted structure, and verified public access. The water tops out around 11 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. Here's the year, species by species, as the scoring engine sees it.
On the chart, South-Central Inshore Biscayne Bay draws 13,457 acres inside 36.4 miles of shoreline — 6 islands included. The 2.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 11.7 mi, about 3 mi across. For a second option, South-Central Mid-Bay Biscayne Bay lies 4 mi south.
The spring pattern is a shallow one: red drum (redfish) in 1 to 8 ft. As the season builds they drop to 2 to 11 ft, wintering in 2 to 11 ft. Top water on the chart: 2004 - 2015 continuous seagrass edge, a seagrass edge in the 5 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a weedless gold spoon or a paddletail swimbait gets it done.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | dawn & dusk | 2004 - 2015 continuous seagrass edge (5 ft) | Gold weedless spoon, Paddletail on 1/4 oz jighead |
| Summer | 2 to 11 ft chart-limited; documented 2 to 12 ft | dawn & dusk | Dangerous NOAA charted wreck (6 ft) | Weedless gold spoon, Paddletail swimbait |
| Fall | 2 to 11 ft chart-limited; documented 3 to 20 ft | dawn & midday | Feeding flat (7 ft) | 1/2 oz spoon (schools), Big paddletail |
| Winter | 2 to 11 ft chart-limited; documented 3 to 15 ft | midday & dawn | Feeding flat (7 ft) | Scented soft plastic on 1/8 oz head, Slow-rolled paddletail |
Spring spotted seatrout on South-Central Inshore Biscayne Bay hold shallow, usually 2 to 10 ft. By summer they slide out to 3 to 11 ft, and by winter most fish are in 3 to 11 ft. The chart's best answer is 2004 - 2015 continuous seagrass edge — seagrass edge, 5 ft, prime for spring. Prime time lands in early morning. The summer box starts with a popping cork + shrimp or a 1/4 oz jighead + paddletail (deep grass edge).

|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | 2004 - 2015 continuous seagrass edge (5 ft) | Topwater walker, Suspending twitchbait |
| Summer | 3 to 11 ft chart-limited; documented 4 to 15 ft | dawn | 2004 - 2015 continuous seagrass edge (5 ft) | Popping cork + shrimp, 1/4 oz jighead + paddletail (deep grass edge) |
| Fall | 3 to 11 ft chart-limited; documented 3 to 12 ft | dawn | 2004 - 2015 continuous seagrass edge (5 ft) | Popping cork rig, Soft plastic jerkbait |
| Winter | 3 to 11 ft chart-limited; documented 5 to 20 ft | midday & dusk | Feeding flat (7 ft) | Suspending twitchbait (long pauses), Scented plastic crawled on bottom |
The spring pattern is a shallow one: snook in 2 to 11 ft. The depth story barely changes: 2 to 11 ft through summer, 3 to 11 ft in winter. The spot to know is 2004 - 2015 continuous seagrass edge, a seagrass edge in about 5 ft of water that rates good for snook in spring. Plan around early morning and the evening in the warm months. Summer baits: a flair hawk jig (passes, night) or a big swimbait in the current gets it done.

Start shallow in spring: sheepshead sit in 2 to 11 ft that time of year. They don't go far with the seasons — 2 to 11 ft covers summer, 3 to 11 ft covers winter. The spot to know is Dangerous NOAA charted wreck, a wreck in about 6 ft of water that rates prime for sheepshead in spring. Warm-month bites cluster around early morning. Throw a small jig + crab piece until the fish tell you otherwise.

Spring puts gulf flounder in skinny water — 2 to 11 ft is the zone. Summer fish stay in 2 to 11 ft, and winter fish hold in 3 to 11 ft. Spring gulf flounder concentrate at 2004 - 2015 continuous seagrass edge, a good-rated seagrass edge around 5 ft. Warm-month bites cluster around early morning and the evening. A paddletail dragged on bottom or a bucktail + swimming mullet covers the summer program.

Spring gray snapper (mangrove snapper) on South-Central Inshore Biscayne Bay hold shallow, usually 2 to 11 ft. Depth-wise the year is flat: 1 to 11 ft in summer, 2 to 11 ft once it turns cold. The chart's best answer is Dangerous NOAA charted wreck — wreck, 6 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a small bucktail or a paddletail.
