32-acre Cromwell Cove fishing map with NOAA BlueTopo survey contours (95.24% measured, 97.62% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 48 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.
The drawn water covers 32 acres wrapped in 1.1 miles of bank, with 2 islands in the mix. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. 56% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 0.4 mi of water from one end to the other, 0.3 mi at the beam. Its nearest charted neighbour, Bar Harbor, is 1 mi to the north.
In spring, striped bass run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 14 to 48 ft, and winter fish settle into 14 to 48 ft. Surveyed channel edge is the standout, a drop-off at roughly 26 ft, rated prime for summer striped bass. Time it for early morning and the evening. You won't need more than a flutter spoon (deep) or an umbrella rig (trolled) most summer days.
| 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 | 14 to 48 ft | dawn & dusk | Surveyed channel edge (26 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (26 ft) | Topwater walker, Jerkbait |
| Winter | 14 to 48 ft | midday | Surveyed channel edge (26 ft) | Alabama rig (slow), Flutter spoon |
Come spring, look for bluefish tight to the bank in 3 to 20 ft. Expect a summer slide to 5 to 30 ft, then a winter hold in 15 to 40 ft. Start at Surveyed channel edge. It's a drop-off holding about 26 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A popper (early/late) or a metal jigs in the rips is the honest summer answer here.
| 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) |
The spring pattern is a shallow one: atlantic mackerel in 5 to 45 ft. As the season builds they drop to 9 to 48 ft, wintering in 12 to 48 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 feather rig or a small vertical jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Surveyed channel edge (26 ft) | Mackerel feather rig, Small silver jig |
| Summer | 9 to 48 ft | dawn & dusk | Surveyed channel edge (26 ft) | Feather rig, Small vertical jig |
| Fall | 7 to 48 ft | dawn & dusk | Surveyed channel edge (26 ft) | Compact silver jig, Sparse feather rig |
| Winter | 12 to 48 ft | midday | Surveyed channel edge (26 ft) | Small deep jig |
Start shallow in spring: atlantic cod sit in 10 to 48 ft that time of year. They don't go far with the seasons — 12 to 48 ft covers summer, 11 to 48 ft covers winter. Top water on the chart: NOAA charted underwater rock, a rock pile in the 11 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a heavy metal jig or a large soft-plastic jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 48 ft | dawn | NOAA charted underwater rock (11 ft) | Diamond jig, Heavy bucktail |
| Summer | 12 to 48 ft | dawn | NOAA charted underwater rock (23 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 9 to 48 ft | dawn | NOAA charted underwater rock (11 ft) | Diamond jig, Bucktail with teaser |
| Winter | 11 to 48 ft | midday | NOAA charted underwater rock (11 ft) | Heavy vertical jig |
When the water first warms, atlantic herring slide up into 5 to 25 ft. By summer they slide out to 14 to 48 ft, and by winter most fish are in 14 to 48 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 26 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a herring feather rig or a small silver jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | NOAA charted underwater rock (11 ft) | Small herring feather rig, Micro jig rig |
| Summer | 14 to 48 ft | dawn & dusk | Surveyed channel edge (26 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 | 14 to 48 ft | midday | Surveyed channel edge (26 ft) | Small silver jig, Sparse feather rig |
Structure-wise the chart holds 5 features, led in depth by Surveyed channel edge at roughly 26 ft.

Cromwell Cove is about 48 ft (15 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 Cromwell Cove.
NOAA charted underwater rock is the top-rated area: a rock pile in about 11 ft of water that rates prime for atlantic cod in spring. Every other rated spot, per species and season, is on the map above.
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 Cromwell Cove 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.
