61-acre lake near Na h-Eileanan an Iar. The lake tops out around 31 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. Here's the year, species by species, as the scoring engine sees it.
On the chart, Loch Hosta draws 61 acres inside 1.3 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 66% of this chart. The basin spans about 0.5 mi end to end and 0.3 mi across at its widest. The water lies in Na h-Eileanan Siar. Closest neighbour on DepthScout: Loch Huna, 6 mi southeast of here.
Spring brown trout on Loch Hosta hold shallow, usually 3 to 25 ft. They move out to 9 to 31 ft in summer and finish the year down in 4 to 31 ft. Put Break off the point first on the milk run — a drop-off near 10 ft that grades prime for summer. The feeding windows run after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).
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 (3 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 9 to 31 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (10 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (3 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 31 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (10 ft) | Jigging spoon, Small stickbait (slow) |
In spring, european perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 9 to 31 ft for winter. Fall european perch concentrate at Deep basin, a prime-rated deep basin around 31 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) 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 | 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 | Break off the point (10 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 9 to 31 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (31 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 9 to 31 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (31 ft) | Tungsten jig + maggots, Small balance jig |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| 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 | Break off the point (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (10 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 |
Come spring, look for arctic char tight to the bank in 4 to 15 ft. Expect a summer slide to 9 to 31 ft, then a winter hold in 8 to 31 ft. Start at Deep basin. It's a deep basin holding about 31 ft of water and rates prime come summer. Prime time lands in early morning. A jigging spoon vertical or a tube jig (smelt) is the honest summer answer here.

The chart marks 6 structure features on Loch Hosta; the deepest is Deep basin at about 31 ft.
Loch Hosta is about 31 ft (9 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 Hosta. 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.
Deep basin is the top-rated area: a deep basin in about 31 ft of water that rates prime for european perch in fall. Every other rated spot, per species and season, is on the map above.
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.
