67-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 1903, digitized from the bathymetric atlas published in 1910. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 67 acres wrapped in 1.6 miles of bank. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 74% of the surface — that's where the groceries are. Tip to tip the water measures near 0.5 mi with a 0.3-mi widest point. It sits in Na h-Eileanan Siar. Its nearest charted neighbour, Loch Crò Chriosdaig, is 3 mi to the west.
In spring, brown trout run shallow here, mostly 3 to 25 ft. Midsummer fish sit out in 9 to 31 ft before dropping to 4 to 31 ft for winter. Summer brown trout concentrate at Deep basin, a prime-rated deep basin around 31 ft. Fish it in after dark and early morning and you'll meet the bite. 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 | 3 to 25 ft | dawn & dusk | Secondary point (6 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 | Deep basin (31 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Secondary point (6 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 31 ft chart-limited; documented 5 to 35 ft | dawn | Deep basin (31 ft) | Jigging spoon, Small stickbait (slow) |
Spring european perch on Loch Morsgail hold shallow, usually 3 to 12 ft. They move out to 8 to 28 ft in summer and finish the year down in 9 to 31 ft. Put Deep basin first on the milk run — a deep basin near 31 ft that grades prime for fall. The feeding windows run 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 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Deep basin (31 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 |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| 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 | Secondary point (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Secondary point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Secondary point (6 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: arctic char sit in 4 to 15 ft that time of year. Summer pushes them deeper, 9 to 31 ft, and winter fish settle into 8 to 31 ft. The spot to know is Deep basin, a deep basin in about 31 ft of water that rates prime for arctic char in summer. Warm-month bites cluster around early morning. Throw a jigging spoon vertical or a tube jig (smelt) until the fish tell you otherwise.

The chart marks 5 structure features on Loch Morsgail; the deepest is Deep basin at about 31 ft.
Loch Morsgail is about 31 ft (9 m) deep at its deepest point. The depth data here comes from Murray & Pullar's Scottish loch survey of 1903, digitized from the bathymetric atlas published in 1910.
Anglers target brown trout, european perch, northern pike, arctic char on Loch Morsgail. 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. Scroll up to the map for the complete spot list by 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.
