965-acre Acushnet River fishing map with NOAA BlueTopo survey contours (79.54% measured, 100% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 53 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. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Acushnet River draws 964 acres inside 19.1 miles of shoreline, broken up by 10 islands. An index of 4.4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 62% of this chart. Tip to tip the water measures near 4.1 mi with a 0.9-mi widest point. The nearest mapped water is Clarks Cove, 3 mi to the south.
Come spring, look for striped bass tight to the bank in 5 to 20 ft. They move out to 16 to 53 ft in summer and finish the year down in 20 to 50 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 15 ft that scores prime in summer. Best bite is early morning and the evening. A flutter spoon (deep) or an umbrella rig (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Surveyed channel edge (12 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 16 to 53 ft | dawn & dusk | Surveyed channel edge (15 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (12 ft) | Topwater walker, Jerkbait |
| Winter | 20 to 50 ft | midday | Surveyed channel edge (15 ft) | Alabama rig (slow), Flutter spoon |
The spring pattern is a shallow one: bluefish in 3 to 20 ft. As the season builds they drop to 5 to 30 ft, wintering in 15 to 40 ft. Top water on the chart: Surveyed channel edge, a drop-off in the 12 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a popper (early/late) or a metal jigs in the rips gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Surveyed channel edge (12 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | Surveyed channel edge (12 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (12 ft) | Pencil popper, Big metal |
| Winter | 15 to 40 ft | midday | Surveyed channel edge (15 ft) | Metal jig worked slow (southern waters) |
Come spring, look for summer flounder (fluke) tight to the bank in 5 to 25 ft. Expect a summer slide to 8 to 35 ft, then a winter hold in 16 to 53 ft. Start at Surveyed channel edge. It's a drop-off holding about 12 ft of water and rates prime come summer. Prime time lands in midday and early morning. A bucktail (1-3 oz by drift speed) or a gulp grub on jighead is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | Surveyed channel edge (12 ft) | Bucktail + Gulp swimming mullet, Hi-lo rig + squid strip |
| Summer | 8 to 35 ft | midday & dawn | Surveyed channel edge (12 ft) | Bucktail (1-3 oz by drift speed), Gulp grub on jighead |
| Fall | 12 to 45 ft | midday | Surveyed channel edge (12 ft) | Heavier bucktail on the lumps, Big Gulp 6" grub |
| Winter | 16 to 53 ft | midday | Surveyed channel edge (15 ft) | Slow bottom rig + strip |
Come spring, look for black sea bass tight to the bank in 10 to 40 ft. They move out to 13 to 53 ft in summer and finish the year down in 16 to 53 ft. If you only fish one area, make it NOAA charted underwater rock: a rock pile around 11 ft that scores prime in spring. Best bite is midday and early morning. A bucktail + grub or a diamond jig + squid teaser is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | midday & dawn | NOAA charted underwater rock (11 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 13 to 53 ft | midday & dawn | NOAA charted underwater rock (35 ft) | Bucktail + grub, Diamond jig + squid teaser |
| Fall | 13 to 53 ft | midday | NOAA charted underwater rock (35 ft) | 3-4 oz vertical jig (deep), Double-teaser rig |
| Winter | 16 to 53 ft | midday | NOAA charted underwater rock (35 ft) | Heavy hi-lo rig on deep wrecks |
In spring, tautog (blackfish) run shallow here, mostly 5 to 25 ft. Midsummer fish sit out in 10 to 35 ft before dropping to 16 to 53 ft for winter. Spring tautog (blackfish) concentrate at Dangerous NOAA charted wreck, a prime-rated wreck around 9 ft. Fish it in early morning and you'll meet the bite. You won't need more than a 1/2-1 oz tog jig + crab most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | Dangerous NOAA charted wreck (9 ft) | Tog jig + green crab half, Bare jig + clam (early) |
| Summer | 10 to 35 ft | dawn | Dangerous NOAA charted wreck (32 ft) | 1/2-1 oz tog jig + crab |
| Fall | 10 to 50 ft | midday | Dangerous NOAA charted wreck (32 ft) | Tog jig + whole green crab, Old-school rig + double crab (deep) |
| Winter | 16 to 53 ft | midday | Dangerous NOAA charted wreck (32 ft) | Heavy jig + crab on deep structure |

Acushnet River is about 53 ft (16 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, summer flounder (fluke), black sea bass, tautog (blackfish) on Acushnet River.
Surveyed channel edge is the top-rated area: a drop-off in about 12 ft of water that rates prime for summer flounder (fluke) in summer. 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 Acushnet River is regulated by the Massachusetts DMF (recreational saltwater). Check the official Massachusetts regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
