33-acre Diamond 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 33 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 33 acres of water rimmed by 1.2 miles of bank. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. Roughly 43% of the water is 15 ft or less, the band where the food chain lives. Call it 0.4 mi long by 0.2 mi wide at the broadest reach. Closest neighbour on DepthScout: Hussey Sound, 1 mi southeast of here.
When the water first warms, striped bass slide up into 5 to 20 ft. Summer is a 10 to 33 ft game here, winter a 10 to 33 ft one. Start at Surveyed channel edge. It's a drop-off holding about 11 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a flutter spoon (deep) or an umbrella rig (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Surveyed channel edge (11 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 10 to 33 ft | dawn & dusk | Surveyed channel edge (11 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 9 to 33 ft | dawn & dusk | Surveyed channel edge (11 ft) | Topwater walker, Jerkbait |
| Winter | 10 to 33 ft | midday | Surveyed channel edge (11 ft) | Alabama rig (slow), Flutter spoon |
Start shallow in spring: bluefish sit in 3 to 20 ft that time of year. Summer pushes them deeper, 5 to 30 ft, and winter fish settle into 10 to 33 ft. The spot to know is Surveyed channel edge, a drop-off in about 11 ft of water that rates prime for bluefish in summer. Warm-month bites cluster around early morning and the evening. Throw a popper (early/late) or a metal jigs in the rips until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Surveyed channel edge (11 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | Surveyed channel edge (11 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (11 ft) | Pencil popper, Big metal |
| Winter | 10 to 33 ft | midday | Surveyed channel edge (11 ft) | Metal jig worked slow (southern waters) |
When the water first warms, atlantic mackerel slide up into 4 to 33 ft. There's no big seasonal slide here — summer means 6 to 33 ft, winter 8 to 33 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 11 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a feather rig or a small vertical jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 33 ft | dawn & dusk | Surveyed channel edge (11 ft) | Mackerel feather rig, Small silver jig |
| Summer | 6 to 33 ft | dawn & dusk | Surveyed channel edge (11 ft) | Feather rig, Small vertical jig |
| Fall | 5 to 33 ft | dawn & dusk | Surveyed channel edge (11 ft) | Compact silver jig, Sparse feather rig |
| Winter | 8 to 33 ft | midday | Surveyed channel edge (11 ft) | Small deep jig |
Spring atlantic cod on Diamond Cove hold shallow, usually 7 to 33 ft. Depth-wise the year is flat: 8 to 33 ft in summer, 8 to 33 ft once it turns cold. The chart's best answer is NOAA charted underwater rock — rock pile, 11 ft, prime for spring. Prime time lands in early morning. The summer box starts with a heavy metal jig or a large soft-plastic jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 33 ft | dawn | NOAA charted underwater rock (11 ft) | Diamond jig, Heavy bucktail |
| Summer | 8 to 33 ft | dawn | NOAA charted underwater rock (11 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 6 to 33 ft | dawn | NOAA charted underwater rock (11 ft) | Diamond jig, Bucktail with teaser |
| Winter | 8 to 33 ft | midday | NOAA charted underwater rock (11 ft) | Heavy vertical jig |
The spring pattern is a shallow one: atlantic herring in 5 to 25 ft. As the season builds they drop to 10 to 33 ft, wintering in 10 to 33 ft. Top water on the chart: Surveyed channel edge, a drop-off in the 11 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a herring feather rig or a small silver jig gets it done.
| 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 | 10 to 33 ft | dawn & dusk | Surveyed channel edge (11 ft) | Herring feather rig, Small silver jig |
| Fall | 8 to 33 ft | dawn & dusk | Surveyed channel edge (11 ft) | Small feather rig, Compact silver spoon |
| Winter | 10 to 33 ft | midday | Surveyed channel edge (11 ft) | Small silver jig, Sparse feather rig |

Diamond Cove is about 33 ft (10 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 Diamond 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. 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.
Fishing on Diamond 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.
