17,401-acre Lower Pine Island Sound section with quality-assured NOAA direct survey soundings and assessed contours, exact-polygon FWC fish occurrence, mapped seagrass and oyster habitat, charted structure, and verified named-water public access. The water tops out around 24 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 the data behind the map says about each species, season by season:
Traced from the shoreline, Lower Pine Island Sound runs 17,439 acres with 73.9 miles of edge — 30 islands included. An index of 4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 98% of the surface — that's where the groceries are. Call it 7.7 mi long by 7.3 mi wide at the broadest reach. Closest neighbour on DepthScout: San Carlos Bay, 7 mi east of here.
Spring puts sheepshead in skinny water — 5 to 24 ft is the zone. Summer fish stay in 3 to 15 ft, and winter fish hold in 7 to 24 ft. Summer sheepshead concentrate at Dangerous NOAA charted wreck, a prime-rated wreck around 3 ft. Warm-month bites cluster around early morning. A small jig + crab piece covers the summer program.
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 | 5 to 24 ft chart-limited; documented 5 to 25 ft | midday & dawn | Dangerous NOAA charted wreck (3 ft) | 1/4 oz jighead + fiddler, Sheepshead jig + shrimp piece |
| Summer | 3 to 15 ft | dawn | Dangerous NOAA charted wreck (3 ft) | Small jig + crab piece |
| Fall | 5 to 20 ft | midday | Dangerous NOAA charted wreck (3 ft) | Jighead + shrimp, Small crab jig |
| Winter | 7 to 24 ft chart-limited; documented 10 to 30 ft | midday | Dangerous NOAA charted wreck (3 ft) | Heavier jig + crab (deep pilings) |
Come spring, look for spotted seatrout tight to the bank in 2 to 10 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 5 to 20 ft. Start at 2021 continuous seagrass edge. It's a seagrass edge holding about 3 ft of water and rates prime come spring. Prime time lands in early morning. A popping cork + shrimp or a 1/4 oz jighead + paddletail (deep grass edge) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | 2021 continuous seagrass edge (3 ft) | Topwater walker, Suspending twitchbait |
| Summer | 4 to 15 ft | dawn | 2021 continuous seagrass edge (4 ft) | Popping cork + shrimp, 1/4 oz jighead + paddletail (deep grass edge) |
| Fall | 3 to 12 ft | dawn | 2021 continuous seagrass edge (3 ft) | Popping cork rig, Soft plastic jerkbait |
| Winter | 5 to 20 ft | midday & dusk | Surveyed channel edge (10 ft) | Suspending twitchbait (long pauses), Scented plastic crawled on bottom |
Come spring, look for gray snapper (mangrove snapper) tight to the bank in 3 to 22 ft. Expect a summer slide to 3 to 24 ft, then a winter hold in 4 to 24 ft. Start at Dangerous NOAA charted wreck. It's a wreck holding about 3 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A small bucktail or a paddletail is the honest summer answer here.
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 | 3 to 22 ft | dawn & dusk | 2021 continuous seagrass edge (3 ft) | Small paddletail, Jighead + shrimp imitation |
| Summer | 3 to 24 ft chart-limited; documented 4 to 30 ft | dawn & dusk | Dangerous NOAA charted wreck (3 ft) | Small bucktail, Paddletail |
| Fall | 3 to 24 ft chart-limited; documented 5 to 35 ft | dawn & dusk | Dangerous NOAA charted wreck (3 ft) | Small vertical jig, Jighead + paddletail |
| Winter | 4 to 24 ft chart-limited; documented 8 to 45 ft | midday | Dangerous NOAA charted wreck (3 ft) | Small jig worked slowly |
Spring puts snook in skinny water — 2 to 12 ft is the zone. Warm water sends them out to 3 to 15 ft; cold water stacks them in 4 to 15 ft. 2021 continuous seagrass edge is the standout, a seagrass edge at roughly 3 ft, rated good for spring snook. Plan around early morning and the evening in the warm months. A flair hawk jig (passes, night) or a big swimbait in the current covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 12 ft | dawn & dusk | 2021 continuous seagrass edge (3 ft) | Paddletail on 1/4 oz head, Suspending twitchbait |
| Summer | 3 to 15 ft | dawn & dusk | 2021 continuous seagrass edge (3 ft) | Flair hawk jig (passes, night), Big swimbait in the current |
| Fall | 2 to 12 ft | dawn & dusk | 2021 continuous seagrass edge (3 ft) | Big paddletail (mullet run), Topwater walker |
| Winter | 4 to 15 ft | midday | open water | Slow-rolled paddletail, Scented jerkbait crawled in canals |
The spring pattern is a shallow one: gag grouper in 4 to 24 ft. The depth story barely changes: 4 to 24 ft through summer, 6 to 24 ft in winter. Top water on the chart: Dangerous NOAA charted wreck, a wreck in the 3 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a deep-diving plug or a heavy paddletail 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 | 4 to 24 ft | dawn & dusk | 2021 continuous seagrass edge (4 ft) | Diving plug over grass potholes, Paddletail near rubble |
| Summer | 4 to 24 ft chart-limited; documented 6 to 35 ft | dawn & dusk | Dangerous NOAA charted wreck (3 ft) | Deep-diving plug, Heavy paddletail |
| Fall | 5 to 24 ft chart-limited; documented 10 to 50 ft | dawn | Dangerous NOAA charted wreck (3 ft) | Deep-diving plug, Vertical jig |
| Winter | 6 to 24 ft chart-limited; documented 20 to 80 ft | midday | Dangerous NOAA charted wreck (3 ft) | Heavy vertical jig |
When the water first warms, permit slide up into 3 to 24 ft. There's no big seasonal slide here — summer means 2 to 24 ft, winter 6 to 24 ft. If you only fish one area, make it Dangerous NOAA charted wreck: a wreck around 3 ft that scores prime in fall. In summer the feeding windows fall in early morning and midday. Keep a crab fly or a crab imitation rigged through the warm months.

Lower Pine Island Sound is about 24 ft (7 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 sheepshead, spotted seatrout, gray snapper (mangrove snapper), snook, gag grouper, permit, gulf flounder, red drum (redfish) on Lower Pine Island Sound.
Dangerous NOAA charted wreck is the top-rated area: a wreck in about 3 ft of water that rates prime for gray snapper (mangrove snapper) in fall. Every other rated spot, per species and season, is on the map above.
For sheepshead, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Lower Pine Island Sound 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.
