Fishing Loch an Dùna: what the data says
73-acre lake near Na h-Eileanan an Iar. The lake tops out around 29 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The season-by-season read for each species follows, from the map's own numbers.
Loch an Dùna maps at 73 acres behind 1.9 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Roughly 61% of the water is 15 ft or less as modeled, the band where the food chain lives.
Brown Trout fishing at Loch an Dùna
Spring puts brown trout in skinny water — 3 to 25 ft is the zone. As the season builds they drop to 9 to 29 ft, wintering in 4 to 29 ft. Summer brown trout concentrate at Break off the point, a prime-rated drop-off around 13 ft. Warm-month bites cluster around after dark and early morning. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 9 to 29 ft | night & dawn | Break off the point (13 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 29 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 29 ft | dawn | Break off the point (13 ft) | Jigging spoon, Small stickbait (slow) |
European Perch fishing at Loch an Dùna
Early season european perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 8 to 28 ft, then a winter hold in 9 to 29 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small crankbait (perch pattern) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Deep basin (25 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 9 to 29 ft | midday | Deep basin (25 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 9 to 29 ft | midday & dawn | Deep basin (25 ft) | Tungsten jig + maggots, Small balance jig |
Northern Pike fishing at Loch an Dùna
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (13 ft) | Bucktail, Weedless spoon over cabbage |
