20-acre Dyer Cove fishing map with NOAA BlueTopo survey contours (100% measured, 100% assessed), source-traceable coastal structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 42 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. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Dyer Cove draws 20 acres inside 0.8 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. About 45% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. The nearest mapped water is Richmond Island Harbor, 3 mi to the southwest.
When the water first warms, striped bass slide up into 5 to 20 ft. By summer they slide out to 13 to 42 ft, and by winter most fish are in 13 to 42 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 12 ft that scores prime in summer. In summer the feeding windows fall in 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 (12 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 13 to 42 ft | dawn & dusk | Surveyed channel edge (12 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (12 ft) | Topwater walker, Jerkbait |
| Winter | 13 to 42 ft | midday | Surveyed channel edge (12 ft) | Alabama rig (slow), Flutter spoon |
Start shallow in spring: bluefish sit in 3 to 20 ft that time of year. Warm water sends them out to 5 to 30 ft; cold water stacks them in 15 to 40 ft. Top water on the chart: Surveyed channel edge, a drop-off in the 12 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. 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 (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 (12 ft) | Metal jig worked slow (southern waters) |
When the water first warms, atlantic mackerel slide up into 5 to 42 ft. There's no big seasonal slide here — summer means 8 to 42 ft, winter 11 to 42 ft. Start at Surveyed channel edge. It's a drop-off holding about 12 ft of water and rates prime come summer. The feeding windows run 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 | 5 to 42 ft | dawn & dusk | Surveyed channel edge (12 ft) | Mackerel feather rig, Small silver jig |
| Summer | 8 to 42 ft | dawn & dusk | Surveyed channel edge (12 ft) | Feather rig, Small vertical jig |
| Fall | 6 to 42 ft | dawn & dusk | Surveyed channel edge (12 ft) | Compact silver jig, Sparse feather rig |
| Winter | 11 to 42 ft | midday | Surveyed channel edge (12 ft) | Small deep jig |
Spring atlantic cod on Dyer Cove hold shallow, usually 8 to 42 ft. Depth-wise the year is flat: 11 to 42 ft in summer, 10 to 42 ft once it turns cold. Put NOAA charted rock bottom first on the milk run — a hard bottom near 11 ft that grades prime for summer. The feeding windows run 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 | 8 to 42 ft | dawn | NOAA charted rock bottom (11 ft) | Diamond jig, Heavy bucktail |
| Summer | 11 to 42 ft | dawn | NOAA charted rock bottom (11 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 8 to 42 ft | dawn | NOAA charted rock bottom (11 ft) | Diamond jig, Bucktail with teaser |
| Winter | 10 to 42 ft | midday | NOAA charted rock bottom (11 ft) | Heavy vertical jig |
The spring pattern is a shallow one: atlantic herring in 5 to 25 ft. Midsummer fish sit out in 13 to 42 ft before dropping to 13 to 42 ft for winter. The spot to know is Surveyed channel edge, a drop-off in about 12 ft of water that rates prime for atlantic herring in summer. Plan around early morning and the evening in the warm months. 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 rock bottom (11 ft) | Small herring feather rig, Micro jig rig |
| Summer | 13 to 42 ft | dawn & dusk | Surveyed channel edge (12 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Surveyed channel edge (12 ft) | Small feather rig, Compact silver spoon |
| Winter | 13 to 42 ft | midday | Surveyed channel edge (12 ft) | Small silver jig, Sparse feather rig |

Dyer Cove is about 42 ft (13 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 Dyer Cove.
NOAA charted rock bottom is the top-rated area: a hard bottom in about 11 ft of water that rates prime for atlantic cod in summer. 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 Dyer 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.
