52-acre lake near Na h-Eileanan an Iar. The lake tops out around 41 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from Murray & Pullar's Scottish loch survey of 1904, digitized from the bathymetric atlas published in 1910. Species by species, here's what the data says the year looks like.
Loch Shiùrabhagh maps at 52 acres behind 4.2 miles of shoreline. With a shoreline index of 4.1, this water is all arms and coves — edge habitat well beyond its acreage. 90% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 0.8 mi of water from one end to the other, 0.5 mi at the beam. Na h-Eileanan Siar claims this one. Its nearest charted neighbour, Loch Theirmeadail or Loch Hermidale, is 1 mi to the north.
Spring puts brown trout in skinny water — 3 to 25 ft is the zone. As the season builds they drop to 12 to 41 ft, wintering in 5 to 35 ft. Summer brown trout concentrate at Deep basin, a prime-rated deep basin around 40 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.
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 | 3 to 25 ft | dawn & dusk | Main-lake point (2 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 12 to 41 ft chart-limited; documented 25 to 60 ft | night & dawn | Deep basin (40 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (2 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Deep basin (40 ft) | Jigging spoon, Small stickbait (slow) |
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 12 to 33 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 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 (2 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Shallow bay flat (2 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Deep basin (40 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Deep basin (40 ft) | Tungsten jig + maggots, Small balance jig |
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 2 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | open water | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (2 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: arctic char in 4 to 15 ft. Midsummer fish sit out in 12 to 41 ft before dropping to 10 to 40 ft for winter. The spot to know is Deep basin, a deep basin in about 40 ft of water that rates prime for arctic char in summer. Plan around early morning in the warm months. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.

| 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 | 12 to 41 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (40 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | open water | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | Deep basin (40 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
Loch Shiùrabhagh carries 5 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 40 ft down.
Loch Shiùrabhagh is about 41 ft (12 m) deep at its deepest point. The depth data here comes from Murray & Pullar's Scottish loch survey of 1904, digitized from the bathymetric atlas published in 1910.
Anglers target brown trout, european perch, northern pike, arctic char on Loch Shiùrabhagh. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Shallow bay flat is the top-rated area: a weed flat in about 2 ft of water that rates prime for northern pike in spring. Open the map above to see every rated spot for each species and season.
For brown trout, the summer bite is best in after dark and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
