1,678-acre Toothacher 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 106 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 follows comes from the same scoring engine that paints the spots above.
On the chart, Toothacher Bay draws 1,675 acres inside 8.9 miles of shoreline, broken up by an island. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. 7% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 2.4 mi, about 1.6 mi across. Closest neighbour on DepthScout: Jericho Bay, 2 mi northwest of here.
Come spring, look for striped bass tight to the bank in 5 to 20 ft. They move out to 25 to 60 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 41 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 | open water | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 25 to 60 ft | dawn & dusk | Surveyed channel edge (41 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (26 ft) | Topwater walker, Jerkbait |
| Winter | 20 to 50 ft | midday | Surveyed channel edge (41 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 26 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 | open water | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | Surveyed channel edge (26 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (26 ft) | Pencil popper, Big metal |
| Winter | 15 to 40 ft | midday | Surveyed channel edge (26 ft) | Metal jig worked slow (southern waters) |
Come spring, look for atlantic mackerel tight to the bank in 5 to 45 ft. Expect a summer slide to 15 to 80 ft, then a winter hold in 27 to 106 ft. Start at Surveyed channel edge. It's a drop-off holding about 41 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A feather rig or a small vertical jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Surveyed channel edge (41 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Surveyed channel edge (41 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Surveyed channel edge (41 ft) | Compact silver jig, Sparse feather rig |
| Winter | 27 to 106 ft | midday | Surveyed channel edge (41 ft) | Small deep jig |
Early season atlantic cod use the shallows, holding in 20 to 100 ft. Expect a summer slide to 27 to 106 ft, then a winter hold in 24 to 106 ft. Put NOAA charted underwater rock first on the milk run — a rock pile near 13 ft that grades prime for fall. In summer the feeding windows fall in early morning. Tie on a heavy metal jig or a large soft-plastic jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 20 to 100 ft | dawn | NOAA charted underwater rock (13 ft) | Diamond jig, Heavy bucktail |
| Summer | 27 to 106 ft | dawn | NOAA charted underwater rock (13 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 19 to 106 ft | dawn | NOAA charted underwater rock (13 ft) | Diamond jig, Bucktail with teaser |
| Winter | 24 to 106 ft | midday | NOAA charted underwater rock (13 ft) | Heavy vertical jig |
Start shallow in spring: atlantic herring sit in 5 to 25 ft that time of year. Summer pushes them deeper, 15 to 50 ft, and winter fish settle into 20 to 60 ft. The spot to know is Surveyed channel edge, a drop-off in about 41 ft of water that rates prime for atlantic herring in summer. Warm-month bites cluster around early morning and the evening. Throw a herring feather rig or a small silver jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | NOAA charted underwater rock (13 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Surveyed channel edge (41 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Surveyed channel edge (26 ft) | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Surveyed channel edge (41 ft) | Small silver jig, Sparse feather rig |

Toothacher Bay is about 106 ft (32 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 Toothacher 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 fall. 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.
