13-acre Blastow Cove 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 35 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. Species by species, here's what the data says the year looks like.
Drawn out, this is 13 acres of water rimmed by 0.7 miles of bank. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. Roughly 81% of the water is 15 ft or less, the band where the food chain lives. Closest neighbour on DepthScout: Eggemoggin Reach, 2 mi northwest of here.
Come spring, look for striped bass tight to the bank in 5 to 20 ft. They move out to 11 to 35 ft in summer and finish the year down in 11 to 35 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 18 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 (18 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 11 to 35 ft | dawn & dusk | Surveyed channel edge (18 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (18 ft) | Topwater walker, Jerkbait |
| Winter | 11 to 35 ft | midday | Surveyed channel edge (18 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 11 to 35 ft. Top water on the chart: Surveyed channel edge, a drop-off in the 18 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 (18 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | Surveyed channel edge (18 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (18 ft) | Pencil popper, Big metal |
| Winter | 11 to 35 ft | midday | Surveyed channel edge (18 ft) | Metal jig worked slow (southern waters) |
Come spring, look for atlantic mackerel tight to the bank in 4 to 35 ft. Through summer count on 7 to 35 ft; the winter hold is 9 to 35 ft. Start at Surveyed channel edge. It's a drop-off holding about 18 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 | 4 to 35 ft | dawn & dusk | Surveyed channel edge (18 ft) | Mackerel feather rig, Small silver jig |
| Summer | 7 to 35 ft | dawn & dusk | Surveyed channel edge (18 ft) | Feather rig, Small vertical jig |
| Fall | 5 to 35 ft | dawn & dusk | Surveyed channel edge (18 ft) | Compact silver jig, Sparse feather rig |
| Winter | 9 to 35 ft | midday | Surveyed channel edge (18 ft) | Small deep jig |
Early season atlantic cod use the shallows, holding in 7 to 35 ft. Even in summer they hold at 9 to 35 ft; winter keeps them in 8 to 35 ft. Put NOAA charted underwater rock first on the milk run — a rock pile near 33 ft that grades prime for spring. 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 | 7 to 35 ft | dawn | NOAA charted underwater rock (33 ft) | Diamond jig, Heavy bucktail |
| Summer | 9 to 35 ft | dawn | NOAA charted underwater rock (33 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 6 to 35 ft | dawn | NOAA charted underwater rock (33 ft) | Diamond jig, Bucktail with teaser |
| Winter | 8 to 35 ft | midday | NOAA charted underwater rock (33 ft) | Heavy vertical jig |
Start shallow in spring: atlantic herring sit in 5 to 25 ft that time of year. Summer pushes them deeper, 11 to 35 ft, and winter fish settle into 11 to 35 ft. The spot to know is Surveyed channel edge, a drop-off in about 18 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 (33 ft) | Small herring feather rig, Micro jig rig |
| Summer | 11 to 35 ft | dawn & dusk | Surveyed channel edge (18 ft) | Herring feather rig, Small silver jig |
| Fall | 9 to 35 ft | dawn & dusk | Surveyed channel edge (18 ft) | Small feather rig, Compact silver spoon |
| Winter | 11 to 35 ft | midday | Surveyed channel edge (18 ft) | Small silver jig, Sparse feather rig |

Blastow Cove is about 35 ft (11 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 Blastow Cove.
NOAA charted underwater rock is the top-rated area: a rock pile in about 33 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.
