2,979-acre Big Lagoon fishing map with NOAA BlueTopo survey contours (69.79% measured, 98.35% assessed), source-traceable wreck, pier, channel, seagrass, shoal and terrain spots, five exact-water fish profiles, four forage calendars, three official public access points and current Florida rules. The water tops out around 26 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. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 2,985 acres, worked by 18 miles of shoreline, broken up by 4 islands. A development index of 2.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. 69% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 6.6 mi of water from one end to the other, 1.2 mi at the beam. Sherman Inlet sits 4 mi east — the closest neighbouring chart.
In spring, gray snapper (mangrove snapper) run shallow here, mostly 3 to 22 ft. Midsummer fish sit out in 3 to 26 ft before dropping to 5 to 26 ft for winter. Summer gray snapper (mangrove snapper) concentrate at NOAA charted pier, a prime-rated dock line around 4 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small bucktail or a paddletail most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 22 ft | dawn & dusk | NOAA charted pier (4 ft) | Small paddletail, Jighead + shrimp imitation |
| Summer | 3 to 26 ft | dawn & dusk | NOAA charted pier (4 ft) | Small bucktail, Paddletail |
| Fall | 4 to 26 ft | dawn & dusk | NOAA charted wreck (19 ft) | Small vertical jig, Jighead + paddletail |
| Winter | 5 to 26 ft | midday | NOAA charted wreck (19 ft) | Small jig worked slowly |
In spring, spotted seatrout run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 5 to 20 ft for winter. Spring spotted seatrout concentrate at 2011 patchy (discontinuous) seagrass edge, a prime-rated seagrass edge around 2 ft. Fish it in early morning and you'll meet the bite. 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 | 2011 patchy (discontinuous) seagrass edge (2 ft) | Topwater walker, Suspending twitchbait |
| Summer | 4 to 15 ft | dawn | 2017 patchy (discontinuous) seagrass edge (4 ft) | Popping cork + shrimp, 1/4 oz jighead + paddletail (deep grass edge) |
| Fall | 3 to 12 ft | dawn | 2017 patchy (discontinuous) seagrass edge (4 ft) | Popping cork rig, Soft plastic jerkbait |
| Winter | 5 to 20 ft | midday & dusk | Perdido Bay channel edge (8 ft) | Suspending twitchbait (long pauses), Scented plastic crawled on bottom |
Spring sheepshead on Big Lagoon hold shallow, usually 5 to 25 ft. Depth-wise the year is flat: 3 to 15 ft in summer, 8 to 26 ft once it turns cold. The chart's best answer is NOAA charted pier — dock line, 4 ft, prime for summer. Prime time lands in early morning. The summer box starts with a small jig + crab piece.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | NOAA charted wreck (19 ft) | 1/4 oz jighead + fiddler, Sheepshead jig + shrimp piece |
| Summer | 3 to 15 ft | dawn | NOAA charted pier (4 ft) | Small jig + crab piece |
| Fall | 5 to 20 ft | midday | NOAA charted pile (7 ft) | Jighead + shrimp, Small crab jig |
| Winter | 8 to 26 ft | midday | NOAA charted wreck (19 ft) | Heavier jig + crab (deep pilings) |
Early season red drum (redfish) use the shallows, holding in 1 to 8 ft. Expect a summer slide to 2 to 12 ft, then a winter hold in 3 to 15 ft. Put Perdido Bay channel edge first on the milk run — a channel edge near 8 ft that grades prime for winter. In summer the feeding windows fall in 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 | 2011 patchy (discontinuous) seagrass edge (2 ft) | Gold weedless spoon, Paddletail on 1/4 oz jighead |
| Summer | 2 to 12 ft | dawn & dusk | Perdido Bay channel edge (8 ft) | Weedless gold spoon, Paddletail swimbait |
| Fall | 3 to 20 ft | dawn & midday | NOAA BlueTopo measured channel shoulder (15 ft) | 1/2 oz spoon (schools), Big paddletail |
| Winter | 3 to 15 ft | midday & dawn | Perdido Bay channel edge (8 ft) | Scented soft plastic on 1/8 oz head, Slow-rolled paddletail |
Spring puts spanish mackerel in skinny water — 4 to 26 ft is the zone. Summer fish stay in 3 to 26 ft, and winter fish hold in 8 to 26 ft. NOAA BlueTopo measured channel shoulder is the standout, a gravel shoal at roughly 15 ft, rated prime for summer spanish mackerel. Plan around early morning and the evening in the warm months. A small spoon trolled or cast or a fast metal jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 26 ft | dawn | NOAA BlueTopo measured channel shoulder (15 ft) | Small casting spoon, Gotcha-style plug |
| Summer | 3 to 26 ft | dawn & dusk | NOAA BlueTopo measured channel shoulder (15 ft) | Small spoon trolled or cast, Fast metal jig |
| Fall | 4 to 26 ft | dawn & midday | NOAA BlueTopo measured channel shoulder (15 ft) | Casting spoon, Small metal jig |
| Winter | 8 to 26 ft | midday | Perdido Bay channel edge (8 ft) | Small metal jig in confirmed offshore water |
Big Lagoon carries 65 mapped structure features, topping out (or rather bottoming out) at Perdido Bay channel edge, about 21 ft down.

Big Lagoon is about 26 ft (8 m) deep at its deepest point. The depth chart is built from real agency bathymetry referenced to NAVD88; directly measured coverage remains distinguished from source interpolation. The contours reflect measured and quality-assessed source depths.
Anglers target gray snapper (mangrove snapper), spotted seatrout, sheepshead, red drum (redfish), spanish mackerel on Big Lagoon.
NOAA charted pier is the top-rated area: a dock line in about 4 ft of water that rates prime for gray snapper (mangrove snapper) in summer. Open the map above to see every rated spot for each species and season.
For gray snapper (mangrove snapper), the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Big Lagoon is regulated by the Florida Fish and Wildlife Conservation Commission (saltwater). Check the official Florida regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
