1,300-acre East Bay fishing map with NOAA BlueTopo survey contours (93.48% measured, 96.7% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 45 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.
On the chart, East Bay draws 1,297 acres inside 21 miles of shoreline, broken up by 4 islands. A development index of 4.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 62% of the surface — that's where the groceries are. Figure 3.2 mi of water from one end to the other, 2.1 mi at the beam. The nearest mapped water is Cobscook Bay, 3 mi to the southeast.
Spring striped bass on East Bay hold shallow, usually 5 to 20 ft. By summer they slide out to 14 to 45 ft, and by winter most fish are in 14 to 45 ft. The chart's best answer is Surveyed channel edge — drop-off, 19 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 | Surveyed channel edge (19 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 14 to 45 ft | dawn & dusk | Surveyed channel edge (19 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (19 ft) | Topwater walker, Jerkbait |
| Winter | 14 to 45 ft | midday | Surveyed channel edge (19 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 19 ft, rated prime 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 | Surveyed channel edge (19 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | Surveyed channel edge (19 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (19 ft) | Pencil popper, Big metal |
| Winter | 15 to 40 ft | midday | Surveyed channel edge (19 ft) | Metal jig worked slow (southern waters) |
Early season atlantic mackerel use the shallows, holding in 5 to 45 ft. Even in summer they hold at 8 to 45 ft; winter keeps them in 11 to 45 ft. The chart's best answer is Surveyed channel edge — drop-off, 19 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 (19 ft) | Mackerel feather rig, Small silver jig |
| Summer | 8 to 45 ft | dawn & dusk | Surveyed channel edge (19 ft) | Feather rig, Small vertical jig |
| Fall | 7 to 45 ft | dawn & dusk | Surveyed channel edge (19 ft) | Compact silver jig, Sparse feather rig |
| Winter | 11 to 45 ft | midday | Surveyed channel edge (19 ft) | Small deep jig |
Come spring, look for atlantic cod tight to the bank in 9 to 45 ft. Through summer count on 11 to 45 ft; the winter hold is 10 to 45 ft. If you only fish one area, make it NOAA charted underwater rock: a rock pile around 13 ft that scores prime in spring. 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 | 9 to 45 ft | dawn | NOAA charted underwater rock (13 ft) | Diamond jig, Heavy bucktail |
| Summer | 11 to 45 ft | dawn | NOAA charted underwater rock (13 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 8 to 45 ft | dawn | NOAA charted underwater rock (13 ft) | Diamond jig, Bucktail with teaser |
| Winter | 10 to 45 ft | midday | NOAA charted underwater rock (13 ft) | Heavy vertical jig |
In spring, atlantic herring run shallow here, mostly 5 to 25 ft. Midsummer fish sit out in 14 to 45 ft before dropping to 14 to 45 ft for winter. Summer atlantic herring concentrate at Surveyed channel edge, a prime-rated drop-off around 19 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 underwater rock (7 ft) | Small herring feather rig, Micro jig rig |
| Summer | 14 to 45 ft | dawn & dusk | Surveyed channel edge (19 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Surveyed channel edge (19 ft) | Small feather rig, Compact silver spoon |
| Winter | 14 to 45 ft | midday | Surveyed channel edge (19 ft) | Small silver jig, Sparse feather rig |
15 pieces of structure are mapped here — NOAA charted underwater rock, around 24 ft, is the deepest of them.

East Bay is about 45 ft (14 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 East Bay.
NOAA charted underwater rock is the top-rated area: a rock pile in about 13 ft of water that rates prime for atlantic cod in spring. The interactive chart above rates every spot for each 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.
