7,911-acre Eggemoggin Reach fishing map with NOAA BlueTopo survey contours (99.97% measured, 100% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 169 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 outline encloses 7,900 acres, worked by 36.3 miles of shoreline, broken up by 20 islands. The 2.9 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 16% of this chart. The basin spans about 14.4 mi end to end and 2.9 mi across at its widest. Deadman Cove sits 2 mi east — the closest neighbouring chart.
The spring pattern is a shallow one: striped bass in 5 to 20 ft. As the season builds they drop to 25 to 60 ft, wintering in 20 to 50 ft. Time it for early morning and the evening. Summer baits: a topwater walker at low light or a paddletail on a light jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | open water | 3-6 inch paddletail, Suspending minnow plug |
| Summer | 25 to 60 ft | dawn & dusk | open water | Topwater walker at low light, Paddletail on a light jig |
| Fall | 10 to 35 ft | dawn & dusk | open water | Pencil popper, Baitfish swimbait |
| Winter | 20 to 50 ft | midday | open water | Slow paddletail, Bucktail near bottom |
Spring bluefish on Eggemoggin Reach hold shallow, usually 3 to 20 ft. By summer they slide out to 5 to 30 ft, and by winter most fish are in 15 to 40 ft. Prime time lands in early morning and the evening. The summer box starts with a popper (early/late) or a metal jigs in the rips.
| 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 | open water | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | open water | Pencil popper, Big metal |
| Winter | 15 to 40 ft | midday | open water | Metal jig worked slow (southern waters) |
In spring, atlantic mackerel run shallow here, mostly 5 to 45 ft. Summer pushes them deeper, 15 to 80 ft, and winter fish settle into 30 to 120 ft. Surveyed channel edge is the standout, a drop-off at roughly 97 ft, rated good for winter atlantic mackerel. Time it for early morning and the evening. You won't need more than a feather rig or a small vertical jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | open water | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Surveyed channel edge (91 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | open water | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Surveyed channel edge (97 ft) | Small deep jig |
In spring, atlantic cod run shallow here, mostly 20 to 100 ft. Midsummer fish sit out in 42 to 169 ft before dropping to 38 to 169 ft for winter. Spring atlantic cod concentrate at NOAA charted underwater rock, a prime-rated rock pile around 25 ft. Fish it in early morning and you'll meet the bite. You won't need more than a heavy metal jig or a large soft-plastic jig most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 20 to 100 ft | dawn | NOAA charted underwater rock (25 ft) | Diamond jig, Heavy bucktail |
| Summer | 42 to 169 ft chart-limited; documented 45 to 180 ft | dawn | NOAA charted rock bottom (58 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 25 to 140 ft | dawn | NOAA charted underwater rock (25 ft) | Diamond jig, Bucktail with teaser |
| Winter | 38 to 169 ft chart-limited; documented 50 to 220 ft | midday | NOAA charted rock bottom (58 ft) | Heavy vertical jig |
Early season atlantic herring use the shallows, holding in 5 to 25 ft. Expect a summer slide to 15 to 50 ft, then a winter hold in 20 to 60 ft. Put NOAA charted underwater rock first on the milk run — a rock pile near 13 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a herring feather rig or a small silver jig and you're in the game.
| 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 | open water | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | open water | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | open water | Small silver jig, Sparse feather rig |
Start shallow in spring: winter flounder sit in 2 to 18 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: NOAA charted pier, a dock line in the 8 ft range, good in spring. Fish it in early morning and you'll meet the bite. Throw a light scented jig worked slowly until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 18 ft | midday & dawn | NOAA charted pier (8 ft) | Small bucktail tipped with worm, Scented grub on a light jig |
| Summer | 8 to 30 ft | dawn | NOAA charted pier (8 ft) | Light scented jig worked slowly |
| Fall | 6 to 25 ft | midday | NOAA charted pier (8 ft) | Small bucktail + worm, Scented bottom jig |
| Winter | 3 to 20 ft | midday | open water | Small bucktail tipped with worm |

Eggemoggin Reach is about 169 ft (52 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, winter flounder on Eggemoggin Reach. The list combines the water's survey records with habitat-filtered species from broader official evidence; those additions are plausible occurrences, not exact-water abundance or guaranteed catches.
NOAA charted underwater rock is the top-rated area: a rock pile in about 25 ft of water that rates prime for atlantic cod in spring. Scroll up to the map for the complete spot list by 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 Eggemoggin Reach 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.
