18-acre Clam Cove fishing map on Gravina Island with NOAA BlueTopo survey contours (100% measured), 2024 ADF&G Gravina Island harvest evidence, measured fishing spots and verified Bar Harbor boat access. The water tops out around 38 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. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 18 acres wrapped in 0.9 miles of bank. A middling shoreline index (1.6) gives it some bays to work without being a maze. About 88% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. Ketchikan Harbor Anchorage Area sits 1 mi north — the closest neighbouring chart.
Spring chinook salmon on Clam Cove hold shallow, usually 5 to 38 ft. Depth-wise the year is flat: 11 to 38 ft in summer, 11 to 38 ft once it turns cold. Put Surveyed channel edge first on the milk run — a drop-off near 17 ft that grades good for spring. The feeding windows run early morning and the evening. The summer box starts with a flasher + fly (green/white) or a magnum spoon on downrigger.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 38 ft | dawn & dusk | Surveyed channel edge (17 ft) | Trolled spoon (orange/gold), Stickbait off planer boards |
| Summer | 11 to 38 ft | dawn & dusk | Surveyed channel edge (17 ft) | Flasher + fly (green/white), Magnum spoon on downrigger |
| Fall | 8 to 38 ft | dawn & dusk | Surveyed channel edge (17 ft) | J-plug (glow), Flasher + fly |
| Winter | 11 to 38 ft | midday | Surveyed channel edge (17 ft) | Small spoon on a slow troll, Stickbait deep |
Early season coho salmon use the shallows, holding in 3 to 25 ft. Expect a summer slide to 11 to 38 ft, then a winter hold in 11 to 38 ft. Put Surveyed channel edge first on the milk run — a drop-off near 17 ft that grades good for summer. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + fly or a medium spoon above the thermocline and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Surveyed channel edge (17 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 11 to 38 ft | dawn & dusk | Surveyed channel edge (17 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 8 to 38 ft | dawn & dusk | Surveyed channel edge (17 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 11 to 38 ft | midday | Surveyed channel edge (17 ft) | Small spoon, slow troll |
Start shallow in spring: pink salmon sit in 5 to 38 ft that time of year. They don't go far with the seasons — 2 to 38 ft covers summer, 8 to 38 ft covers winter. The spot to know is NOAA charted rock bottom, a hard bottom in about 5 ft of water that rates prime for pink salmon in summer. Warm-month bites cluster around early morning and the evening. Throw a pink or orange casting spoon or a small hoochie until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 38 ft | dawn & dusk | Surveyed channel edge (17 ft) | Small chrome spoon, Compact herring-pattern jig |
| Summer | 2 to 38 ft | dawn & dusk | NOAA charted rock bottom (5 ft) | Pink or orange casting spoon, Small hoochie |
| Fall | 1 to 38 ft | dawn & dusk | NOAA charted pier (11 ft) | Small bright spoon, Pink jig |
| Winter | 8 to 38 ft | midday | Surveyed channel edge (17 ft) | Small vertical jig |
Come spring, look for chum salmon tight to the bank in 5 to 38 ft. Through summer count on 2 to 38 ft; the winter hold is 10 to 38 ft. If you only fish one area, make it NOAA charted rock bottom: a hard bottom around 5 ft that scores prime in summer. Best bite is early morning and the evening. A chartreuse or pink hoochie or a bright spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 38 ft | dawn & dusk | Surveyed channel edge (17 ft) | Chrome spoon, Compact baitfish jig |
| Summer | 2 to 38 ft | dawn & dusk | NOAA charted rock bottom (5 ft) | Chartreuse or pink hoochie, Bright spoon |
| Fall | 2 to 38 ft | dawn & dusk | NOAA charted rock bottom (5 ft) | Bright spinner, Pink or chartreuse jig |
| Winter | 10 to 38 ft | midday | Surveyed channel edge (17 ft) | Compact vertical jig |
In spring, pacific halibut run shallow here, mostly 8 to 38 ft. Summer keeps them at 4 to 38 ft, and they winter in 10 to 38 ft. Fall pacific halibut concentrate at NOAA charted rock bottom, a prime-rated hard bottom around 11 ft. Fish it in midday and early morning and you'll meet the bite. You won't need more than a heavy vertical jig or a large swimbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 38 ft | dawn | NOAA charted rock bottom (11 ft) | Heavy glow jig, Large grub on lead head |
| Summer | 4 to 38 ft | midday & dawn | NOAA charted rock bottom (5 ft) | Heavy vertical jig, Large swimbait |
| Fall | 6 to 38 ft | midday | NOAA charted rock bottom (11 ft) | Heavy glow jig, Large grub |
| Winter | 10 to 38 ft | midday | Surveyed channel edge (17 ft) | Heavy slow-pitch jig |
Early season lingcod use the shallows, holding in 7 to 38 ft. Even in summer they hold at 4 to 38 ft; winter keeps them in 10 to 38 ft. Put NOAA charted rock bottom first on the milk run — a hard bottom near 11 ft that grades prime for winter. In summer the feeding windows fall in midday and early morning. Tie on a heavy swimbait or a metal jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 38 ft | dawn | NOAA charted rock bottom (11 ft) | Heavy swimbait, Metal jig |
| Summer | 4 to 38 ft | midday & dawn | NOAA charted rock bottom (5 ft) | Heavy swimbait, Metal jig |
| Fall | 6 to 38 ft | midday | NOAA charted rock bottom (11 ft) | Heavy metal jig, Large swimbait |
| Winter | 10 to 38 ft | midday | NOAA charted rock bottom (11 ft) | Heavy slow-pitch jig |
