Fishing Loch an Dùin: what the data says
143-acre lake near Na h-Eileanan an Iar. The lake tops out around 35 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. What the data behind the map says about each species, season by season:
The drawn water covers 143 acres wrapped in 7.4 miles of bank. With a shoreline index of 4.4, this water is all arms and coves — edge habitat well beyond its acreage. About 84% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone.
Brown Trout fishing at Loch an Dùin
The spring pattern is a shallow one: brown trout in 3 to 25 ft. Midsummer fish sit out in 11 to 35 ft before dropping to 5 to 35 ft for winter. The spot to know is Deep basin, a deep basin in about 30 ft of water that rates prime for brown trout in summer. Plan around after dark and early morning in the warm months. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (9 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 11 to 35 ft | night & dawn | Deep basin (30 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (9 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Deep basin (30 ft) | Jigging spoon, Small stickbait (slow) |
European Perch fishing at Loch an Dùin
Come spring, look for european perch tight to the bank in 3 to 12 ft. They move out to 8 to 28 ft in summer and finish the year down in 12 to 33 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Deep basin (30 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Deep basin (30 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Deep basin (30 ft) | Tungsten jig + maggots, Small balance jig |
Northern Pike fishing at Loch an Dùin
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is a 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 4 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (9 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
Arctic Char fishing at Loch an Dùin
In spring, arctic char run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 11 to 35 ft, and winter fish settle into 9 to 35 ft. Deep basin is the standout, a deep basin at roughly 30 ft, rated prime for summer arctic char. Time it for early morning. You won't need more than a jigging spoon vertical or a tube jig (smelt) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | open water | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 11 to 35 ft | dawn | Deep basin (30 ft) | Jigging spoon vertical, Tube jig (smelt) |
