4-acre lake near Argyll and Bute. The lake tops out around 11 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.
The drawn water covers 4 acres wrapped in 0.4 miles of bank. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Argyll and Bute claims this one. If the bite dies, Loch na Sgorra is 1 mi to the north.
In spring, brown trout run shallow here, mostly 1 to 11 ft. Summer keeps them at 3 to 11 ft, and they winter in 2 to 11 ft. Break off the point is the standout, a drop-off at roughly 5 ft, rated prime for summer brown trout. Time it for after dark and early morning. You won't need more than a spoon at the thermocline or a deep stickbait (night) 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 | 1 to 11 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 3 to 11 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (5 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 2 to 11 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |

Spring european perch on Loch Glas-bheinn hold shallow, usually 3 to 11 ft. Depth-wise the year is flat: 3 to 11 ft in summer, 3 to 11 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 9 ft, prime for fall. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small crankbait (perch pattern).

| Season | Depth | Best window | Start at | Go-to baits |

| Spring | 3 to 11 ft chart-limited; documented 3 to 12 ft | midday & dawn | Break off the point (5 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 3 to 11 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (9 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 3 to 11 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 3 to 11 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (9 ft) | Tungsten jig + maggots, Small balance jig |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 3 to 11 ft, and by winter most fish are in 3 to 11 ft. If you only fish one area, make it Break off the point: a drop-off around 5 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 9 ft.
Loch Glas-bheinn is about 11 ft (3 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target brown trout, european perch, northern pike on Loch Glas-bheinn. 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 9 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.
