1,789-acre Eastern Bay fishing map with NOAA BlueTopo survey contours (98.41% measured, 99.55% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 121 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:
The outline encloses 1,787 acres, worked by 9.2 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. Roughly 14% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 2.9 mi with a 2.1-mi widest point. If the bite dies, Lake Wood is 3 mi to the south.
Spring puts striped bass in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 25 to 60 ft, wintering in 20 to 50 ft. Summer striped bass concentrate at Surveyed channel edge, a good-rated drop-off around 52 ft. Warm-month bites cluster around early morning and the evening. A topwater walker at low light or a paddletail on a light jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | open water | 3-6 inch paddletail, Suspending minnow plug |
| Summer | 25 to 60 ft | dawn & dusk | Surveyed channel edge (52 ft) | Topwater walker at low light, Paddletail on a light jig |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (24 ft) | Pencil popper, Baitfish swimbait |
| Winter | 20 to 50 ft | midday | Surveyed channel edge (44 ft) | Slow paddletail, Bucktail near bottom |
When the water first warms, bluefish slide up into 3 to 20 ft. By summer they slide out to 5 to 30 ft, and by winter most fish are in 15 to 40 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 24 ft that scores good in summer. In summer the feeding windows fall in early morning and the evening. Keep a popper (early/late) or a metal jigs in the rips rigged through the warm months.
| 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 (24 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (24 ft) | Pencil popper, Big metal |
| Winter | 15 to 40 ft | midday | open water | Metal jig worked slow (southern waters) |
Start shallow in spring: atlantic mackerel sit in 5 to 45 ft that time of year. Summer pushes them deeper, 15 to 80 ft, and winter fish settle into 30 to 120 ft. The spot to know is Surveyed channel edge, a drop-off in about 52 ft of water that rates good for atlantic mackerel in summer. Warm-month bites cluster around early morning and the evening. Throw a feather rig or a small vertical jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Surveyed channel edge (44 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Surveyed channel edge (52 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Surveyed channel edge (52 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Surveyed channel edge (52 ft) | Small deep jig |
The spring pattern is a shallow one: atlantic cod in 20 to 100 ft. Midsummer fish sit out in 30 to 121 ft before dropping to 28 to 121 ft for winter. The spot to know is NOAA charted underwater rock, a rock pile in about 18 ft of water that rates prime for atlantic cod in spring. Plan around early morning in the warm months. Summer baits: a heavy metal jig or a large soft-plastic jig 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 | 20 to 100 ft | dawn | NOAA charted underwater rock (18 ft) | Diamond jig, Heavy bucktail |
| Summer | 30 to 121 ft chart-limited; documented 45 to 180 ft | dawn | Dangerous NOAA charted wreck (54 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 22 to 121 ft chart-limited; documented 25 to 140 ft | dawn | NOAA charted underwater rock (18 ft) | Diamond jig, Bucktail with teaser |
| Winter | 28 to 121 ft chart-limited; documented 50 to 220 ft | midday | Dangerous NOAA charted wreck (54 ft) | Heavy vertical jig |
Come spring, look for atlantic herring tight to the bank in 5 to 25 ft. Expect a summer slide to 15 to 50 ft, then a winter hold in 20 to 60 ft. Start at NOAA charted underwater rock. It's a rock pile holding about 14 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A herring feather rig or a small silver jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | NOAA charted underwater rock (14 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Surveyed channel edge (44 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Surveyed channel edge (24 ft) | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Surveyed channel edge (52 ft) | Small silver jig, Sparse feather rig |
Spring puts winter flounder in skinny water — 2 to 18 ft is the zone. Warm water sends them out to 8 to 30 ft; cold water stacks them in 3 to 20 ft. Surveyed channel edge is the standout, a drop-off at roughly 24 ft, rated good for fall winter flounder. Plan around early morning in the warm months. A light scented jig worked slowly covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 18 ft | midday & dawn | NOAA charted underwater rock (14 ft) | Small bucktail tipped with worm, Scented grub on a light jig |
| Summer | 8 to 30 ft | dawn | Surveyed channel edge (24 ft) | Light scented jig worked slowly |
| Fall | 6 to 25 ft | midday | Surveyed channel edge (24 ft) | Small bucktail + worm, Scented bottom jig |
| Winter | 3 to 20 ft | midday | open water | Small bucktail tipped with worm |
12 pieces of structure are mapped here — Dangerous NOAA charted wreck, around 54 ft, is the deepest of them.

Eastern Bay is about 121 ft (37 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 Eastern 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 18 ft of water that rates prime for atlantic cod in spring. The map above holds the full rated-spot list for every 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 Eastern 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.
