58,980-acre outer Tampa Bay section with NOAA survey contours across passes, channels, reefs, wrecks and seagrass edges. The water tops out around 80 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. Species by species, here's what the data says the year looks like.
On the chart, Lower Tampa Bay draws 59,105 acres inside 130.8 miles of shoreline — 84 islands included. A development index of 3.8 means a maze of bays and points: far more casting targets than a round bowl of the same size. Littoral water — the productive band under ~15 ft — makes up 45% of this chart. Call it 13.6 mi long by 11 mi wide at the broadest reach. The nearest mapped water is Mullet Key Bayou, 5 mi to the northwest.
The spring pattern is a shallow one: snook in 2 to 12 ft. As the season builds they drop to 3 to 15 ft, wintering in 4 to 15 ft. Top water on the chart: 2024 continuous seagrass edge, a seagrass edge in the 4 ft range, good in spring. Time it for early morning and the evening. Summer baits: a flair hawk jig (passes, night) or a big swimbait in the current gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 12 ft | dawn & dusk | 2024 continuous seagrass edge (4 ft) | Paddletail on 1/4 oz head, Suspending twitchbait |
| Summer | 3 to 15 ft | dawn & dusk | 2024 continuous seagrass edge (4 ft) | Flair hawk jig (passes, night), Big swimbait in the current |
| Fall | 2 to 12 ft | dawn & dusk | 2024 continuous seagrass edge (4 ft) | Big paddletail (mullet run), Topwater walker |
| Winter | 4 to 15 ft | midday | open water | Slow-rolled paddletail, Scented jerkbait crawled in canals |
Start shallow in spring: sheepshead sit in 5 to 25 ft that time of year. They don't go far with the seasons — 3 to 15 ft covers summer, 10 to 30 ft covers winter. Top water on the chart: Egmont Key Reef (Bay), 25, an artificial reef in the 21 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a small jig + crab piece until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | Egmont Key Reef (Bay), 25 (21 ft) | 1/4 oz jighead + fiddler, Sheepshead jig + shrimp piece |
| Summer | 3 to 15 ft | dawn | 2024 oyster bars edge (3 ft) | Small jig + crab piece |
| Fall | 5 to 20 ft | midday | Egmont Key Reef (Bay), 13 (20 ft) | Jighead + shrimp, Small crab jig |
| Winter | 10 to 30 ft | midday | Egmont Key Reef (Bay), 25 (21 ft) | Heavier jig + crab (deep pilings) |
Spring spotted seatrout on Lower Tampa Bay hold shallow, usually 2 to 10 ft. They move out to 4 to 15 ft in summer and finish the year down in 5 to 20 ft. Put 2024 continuous seagrass edge first on the milk run — a seagrass edge near 4 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a popping cork + shrimp or a 1/4 oz jighead + paddletail (deep grass edge).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | 2024 continuous seagrass edge (4 ft) | Topwater walker, Suspending twitchbait |
| Summer | 4 to 15 ft | dawn | 2024 continuous seagrass edge (4 ft) | Popping cork + shrimp, 1/4 oz jighead + paddletail (deep grass edge) |
| Fall | 3 to 12 ft | dawn | 2024 continuous seagrass edge (4 ft) | Popping cork rig, Soft plastic jerkbait |
| Winter | 5 to 20 ft | midday & dusk | Shallow feeding flat (17 ft) | Suspending twitchbait (long pauses), Scented plastic crawled on bottom |
The spring pattern is a shallow one: red drum (redfish) in 1 to 8 ft. Midsummer fish sit out in 2 to 12 ft before dropping to 3 to 15 ft for winter. The spot to know is 2024 oyster bars edge, an oyster reef in about 3 ft of water that rates prime for red drum (redfish) in spring. Plan around early morning and the evening in the warm months. Summer baits: a weedless gold spoon or a paddletail swimbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | dawn & dusk | 2024 oyster bars edge (3 ft) | Gold weedless spoon, Paddletail on 1/4 oz jighead |
| Summer | 2 to 12 ft | dawn & dusk | 2024 oyster bars edge (3 ft) | Weedless gold spoon, Paddletail swimbait |
| Fall | 3 to 20 ft | dawn & midday | 2024 oyster bars edge (3 ft) | 1/2 oz spoon (schools), Big paddletail |
| Winter | 3 to 15 ft | midday & dawn | Shallow feeding flat (16 ft) | Scented soft plastic on 1/8 oz head, Slow-rolled paddletail |
Spring gray snapper (mangrove snapper) on Lower Tampa Bay hold shallow, usually 3 to 22 ft. They move out to 4 to 30 ft in summer and finish the year down in 8 to 45 ft. Put Egmont Key Reef (Bay), 25 first on the milk run — an artificial reef near 21 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a small bucktail or a paddletail.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 22 ft | dawn & dusk | Egmont Key Reef (Bay), 25 (21 ft) | Small paddletail, Jighead + shrimp imitation |
| Summer | 4 to 30 ft | dawn & dusk | Egmont Key Reef (Bay), 25 (21 ft) | Small bucktail, Paddletail |
| Fall | 5 to 35 ft | dawn & dusk | Egmont Key Reef (Bay), 25 (21 ft) | Small vertical jig, Jighead + paddletail |
| Winter | 8 to 45 ft | midday | Egmont Key Reef (Bay), 25 (21 ft) | Small jig worked slowly |
Spring puts gulf flounder in skinny water — 2 to 14 ft is the zone. Warm water sends them out to 4 to 20 ft; cold water stacks them in 12 to 40 ft. 2024 continuous seagrass edge is the standout, a seagrass edge at roughly 4 ft, rated good for spring gulf flounder. Plan around early morning and the evening in the warm months. A paddletail dragged on bottom or a bucktail + swimming mullet covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 14 ft | dawn | 2024 continuous seagrass edge (4 ft) | 1/4 oz jighead + paddletail, Bucktail + scented shrimp |
| Summer | 4 to 20 ft | dawn & dusk | 2024 continuous seagrass edge (4 ft) | Paddletail dragged on bottom, Bucktail + swimming mullet |
| Fall | 6 to 28 ft | midday & dusk | Shallow feeding flat (17 ft) | 3/8 oz bucktail + scented grub, Paddletail on a heavier jighead |
| Winter | 12 to 40 ft | midday | Sharp break (41 ft) | Slow jig + scented grub |
