328-acre Flanders Bay fishing map with NOAA BlueTopo survey contours (100% measured, 100% assessed), source-traceable coastal structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 68 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.
Drawn out, this is 328 acres of water rimmed by 3.3 miles of bank. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. About 0% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1.3 mi long by 0.7 mi wide at the broadest reach. The nearest mapped water is Eastern Point Harbor, 2 mi to the west.
Spring striped bass on Flanders Bay hold shallow, usually 5 to 20 ft. By summer they slide out to 25 to 60 ft, and by winter most fish are in 20 to 50 ft. The chart's best answer is Surveyed channel edge — drop-off, 50 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a flutter spoon (deep) or an umbrella rig (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | open water | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 25 to 60 ft | dawn & dusk | Surveyed channel edge (50 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (35 ft) | Topwater walker, Jerkbait |
| Winter | 20 to 50 ft | midday | Surveyed channel edge (50 ft) | Alabama rig (slow), Flutter spoon |
Spring puts bluefish in skinny water — 3 to 20 ft is the zone. Warm water sends them out to 5 to 30 ft; cold water stacks them in 15 to 40 ft. Surveyed channel edge is the standout, a drop-off at roughly 35 ft, rated good for summer bluefish. Plan around early morning and the evening in the warm months. A popper (early/late) or a metal jigs in the rips covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | open water | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | Surveyed channel edge (35 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | open water | Pencil popper, Big metal |
| Winter | 15 to 40 ft | midday | Surveyed channel edge (35 ft) | Metal jig worked slow (southern waters) |
Early season atlantic mackerel use the shallows, holding in 5 to 45 ft. Summer is a 13 to 68 ft game here, winter a 17 to 68 ft one. The chart's best answer is Surveyed channel edge — drop-off, 50 ft, prime for summer. Best bite is early morning and the evening. Tie on a feather rig or a small vertical jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Surveyed channel edge (35 ft) | Mackerel feather rig, Small silver jig |
| Summer | 13 to 68 ft | dawn & dusk | Surveyed channel edge (50 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Surveyed channel edge (50 ft) | Compact silver jig, Sparse feather rig |
| Winter | 17 to 68 ft | midday | Surveyed channel edge (50 ft) | Small deep jig |
Come spring, look for atlantic cod tight to the bank in 14 to 68 ft. Through summer count on 17 to 68 ft; the winter hold is 15 to 68 ft. If you only fish one area, make it NOAA charted rock: a hard bottom around 30 ft that scores prime in summer. Best bite is early morning. A heavy metal jig or a large soft-plastic jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 14 to 68 ft | dawn | NOAA charted rock (30 ft) | Diamond jig, Heavy bucktail |
| Summer | 17 to 68 ft | dawn | NOAA charted rock (30 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 12 to 68 ft | dawn | NOAA charted rock (30 ft) | Diamond jig, Bucktail with teaser |
| Winter | 15 to 68 ft | midday | NOAA charted rock (30 ft) | Heavy vertical jig |
In spring, atlantic herring run shallow here, mostly 5 to 25 ft. Midsummer fish sit out in 15 to 50 ft before dropping to 20 to 60 ft for winter. Summer atlantic herring concentrate at Surveyed channel edge, a prime-rated drop-off around 50 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a herring feather rig or a small silver jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | NOAA charted rock (30 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Surveyed channel edge (50 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Surveyed channel edge (35 ft) | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Surveyed channel edge (50 ft) | Small silver jig, Sparse feather rig |

Flanders Bay is about 68 ft (21 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 striped bass, bluefish, atlantic mackerel, atlantic cod, atlantic herring on Flanders Bay.
NOAA charted rock is the top-rated area: a hard bottom in about 30 ft of water that rates prime for atlantic cod in summer. Scroll up to the map for the complete spot list by species and season.
For striped bass, 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.
