321-acre Sagadahoc Bay fishing map with NOAA BlueTopo survey contours (100% measured, 100% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 12 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 321 acres of water rimmed by 5.1 miles of bank, with a single island in the mix. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 1.4 mi long by 0.7 mi wide at the broadest reach. Closest neighbour on DepthScout: Stage Island Bay, 1 mi south of here.
Spring striped bass on Sagadahoc Bay hold shallow, usually 3 to 12 ft. Depth-wise the year is flat: 4 to 12 ft in summer, 4 to 12 ft once it turns cold. Put Surveyed channel edge first on the milk run — a drop-off near 7 ft that grades good for summer. The feeding windows run early morning and the evening. The summer box starts with a topwater walker at low light or a paddletail on a light jig.
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 12 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Surveyed channel edge (7 ft) | 3-6 inch paddletail, Suspending minnow plug |
| Summer | 4 to 12 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Surveyed channel edge (7 ft) | Topwater walker at low light, Paddletail on a light jig |
| Fall | 3 to 12 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Surveyed channel edge (7 ft) | Pencil popper, Baitfish swimbait |
| Winter | 4 to 12 ft chart-limited; documented 20 to 50 ft | midday | Surveyed channel edge (7 ft) | Slow paddletail, Bucktail near bottom |
Spring puts bluefish in skinny water — 2 to 12 ft is the zone. Summer fish stay in 2 to 12 ft, and winter fish hold in 4 to 12 ft. Summer bluefish concentrate at Surveyed channel edge, a good-rated drop-off around 7 ft. Warm-month bites cluster around early morning and the evening. A popper (early/late) or a metal jigs in the rips covers the summer program.

| Winter | 4 to 12 ft chart-limited; documented 15 to 40 ft | midday | open water | Metal jig worked slow (southern waters) |
Early season atlantic mackerel use the shallows, holding in 1 to 12 ft. Even in summer they hold at 2 to 12 ft; winter keeps them in 3 to 12 ft. Put Surveyed channel edge first on the milk run — a drop-off near 7 ft that grades good for summer. In summer the feeding windows fall in early morning and the evening. Tie on a feather rig or a small vertical jig and you're in the game.

| Spring | 1 to 12 ft chart-limited; documented 5 to 45 ft | dawn & dusk | Surveyed channel edge (7 ft) | Mackerel feather rig, Small silver jig |
| Summer | 2 to 12 ft chart-limited; documented 15 to 80 ft | dawn & dusk | Surveyed channel edge (7 ft) | Feather rig, Small vertical jig |

| Winter | 3 to 12 ft chart-limited; documented 30 to 120 ft | midday | Surveyed channel edge (7 ft) | Small deep jig |
Come spring, look for atlantic cod tight to the bank in 2 to 12 ft. Through summer count on 3 to 12 ft; the winter hold is 3 to 12 ft. Start at NOAA charted underwater rock. It's a rock pile holding about 5 ft of water and rates prime come spring. Prime time lands in 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 | 2 to 12 ft chart-limited; documented 20 to 100 ft | dawn | NOAA charted underwater rock (5 ft) | Diamond jig, Heavy bucktail |
| Summer | 3 to 12 ft chart-limited; documented 45 to 180 ft | dawn | NOAA charted underwater rock (5 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 2 to 12 ft chart-limited; documented 25 to 140 ft | dawn | NOAA charted underwater rock (5 ft) | Diamond jig, Bucktail with teaser |
| Winter | 3 to 12 ft chart-limited; documented 50 to 220 ft | midday | NOAA charted underwater rock (5 ft) | Heavy vertical jig |
In spring, atlantic herring run shallow here, mostly 2 to 12 ft. Summer keeps them at 4 to 12 ft, and they winter in 4 to 12 ft. NOAA charted underwater rock is the standout, a rock pile at roughly 5 ft, rated prime for spring atlantic herring. Time it for early morning and the evening. You won't need more than a herring feather rig or a small silver jig most summer days.

When the water first warms, winter flounder slide up into 1 to 12 ft. There's no big seasonal slide here — summer means 3 to 12 ft, winter 2 to 12 ft. Start at Surveyed channel edge. It's a drop-off holding about 7 ft of water and rates good come spring. The feeding windows run early morning. Keep a light scented jig worked slowly rigged through the warm months.

6 pieces of structure are mapped here — Surveyed channel edge, around 7 ft, is the deepest of them.

Sagadahoc Bay is about 12 ft (4 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, winter flounder on Sagadahoc Bay. The list combines the water's survey records with habitat-filtered species from broader official evidence; those additions are plausible occurrences, not exact-water abundance or guaranteed catches.
NOAA charted underwater rock is the top-rated area: a rock pile in about 5 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.
Fishing on Sagadahoc Bay is regulated by the Maine DMR (saltwater recreational fishing). Check the official Maine regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
