193-acre Stage Island Bay fishing map with NOAA BlueTopo survey contours (73.38% measured, 99.28% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 64 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:
Stage Island Bay maps at 193 acres behind 2.8 miles of shoreline — one island included. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 18% of the surface — that's where the groceries are. Call it 0.7 mi long by 0.6 mi wide at the broadest reach. Its nearest charted neighbour, Sagadahoc Bay, is 1 mi to the north.
Start shallow in spring: striped bass sit in 5 to 20 ft that time of year. Summer pushes them deeper, 25 to 60 ft, and winter fish settle into 20 to 50 ft. The spot to know is Surveyed channel edge, a drop-off in about 39 ft of water that rates prime for striped bass in summer. Warm-month bites cluster around early morning and the evening. Throw a flutter spoon (deep) or an umbrella rig (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Surveyed channel edge (20 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 25 to 60 ft | dawn & dusk | Surveyed channel edge (39 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (24 ft) | Topwater walker, Jerkbait |
| Winter | 20 to 50 ft | midday | Surveyed channel edge (39 ft) | Alabama rig (slow), Flutter spoon |
Early season bluefish use the shallows, holding in 3 to 20 ft. Expect a summer slide to 5 to 30 ft, then a winter hold in 15 to 40 ft. Put Surveyed channel edge first on the milk run — a drop-off near 24 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a popper (early/late) or a metal jigs in the rips and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Shallow feeding flat (7 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | Surveyed channel edge (24 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Shallow feeding flat (7 ft) | Pencil popper, Big metal |
| Winter | 15 to 40 ft | midday | Surveyed channel edge (39 ft) | Metal jig worked slow (southern waters) |
Spring puts atlantic mackerel in skinny water — 5 to 45 ft is the zone. As the season builds they drop to 12 to 64 ft, wintering in 16 to 64 ft. Summer atlantic mackerel concentrate at Surveyed channel edge, a prime-rated drop-off around 39 ft. Warm-month bites cluster around early morning and the evening. A feather rig or a small vertical jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Surveyed channel edge (39 ft) | Mackerel feather rig, Small silver jig |
| Summer | 12 to 64 ft | dawn & dusk | Surveyed channel edge (39 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 64 ft | dawn & dusk | Surveyed channel edge (39 ft) | Compact silver jig, Sparse feather rig |
| Winter | 16 to 64 ft | midday | Surveyed channel edge (39 ft) | Small deep jig |
Spring puts atlantic cod in skinny water — 13 to 64 ft is the zone. Summer fish stay in 16 to 64 ft, and winter fish hold in 15 to 64 ft. NOAA charted underwater rock is the standout, a rock pile at roughly 22 ft, rated prime for spring atlantic cod. Plan around early morning in the warm months. A heavy metal jig or a large soft-plastic jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 13 to 64 ft | dawn | NOAA charted underwater rock (22 ft) | Diamond jig, Heavy bucktail |
| Summer | 16 to 64 ft | dawn | NOAA charted underwater rock (22 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 11 to 64 ft | dawn | NOAA charted underwater rock (22 ft) | Diamond jig, Bucktail with teaser |
| Winter | 15 to 64 ft | midday | NOAA charted underwater rock (22 ft) | Heavy vertical jig |
Spring atlantic herring on Stage Island Bay hold shallow, usually 5 to 25 ft. By summer they slide out to 15 to 50 ft, and by winter most fish are in 20 to 60 ft. The chart's best answer is Surveyed channel edge — drop-off, 39 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a herring feather rig or a small silver jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | NOAA charted underwater rock (22 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Surveyed channel edge (39 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Surveyed channel edge (39 ft) | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Surveyed channel edge (39 ft) | Small silver jig, Sparse feather rig |
Structure-wise the chart holds 5 features, led in depth by Surveyed channel edge at roughly 39 ft.

Stage Island Bay is about 64 ft (20 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 Stage Island Bay.
NOAA charted underwater rock is the top-rated area: a rock pile in about 22 ft of water that rates prime for atlantic cod in spring. Every other rated spot, per species and season, is on the map above.
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.
