138-acre lake near Dumfries and Galloway. The lake tops out around 55 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 138 acres, worked by 4.1 miles of shoreline. An index of 2.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 44% of this chart, as modeled. Call it 1.6 mi long by 0.4 mi wide at the broadest reach. It sits in Dumfries and Galloway. Long Loch of Glenhead sits 2 mi east — the closest neighbouring chart.
The spring pattern is a shallow one: brown trout in 3 to 25 ft. Midsummer fish sit out in 17 to 55 ft before dropping to 5 to 35 ft for winter. The spot to know is Deep basin, a deep basin in about 47 ft of water that rates prime for brown trout in summer. Plan around after dark and early morning in the warm months. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.
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 (14 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 17 to 55 ft chart-limited; documented 25 to 60 ft | night & dawn | Deep basin (47 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (14 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Deep basin (47 ft) | Jigging spoon, Small stickbait (slow) |
Come spring, look for european perch tight to the bank in 3 to 12 ft. They move out to 8 to 28 ft in summer and finish the year down in 12 to 33 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | open water | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | open water | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 6 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
In spring, arctic char run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 17 to 55 ft, and winter fish settle into 10 to 40 ft. Deep basin is the standout, a deep basin at roughly 47 ft, rated prime for summer arctic char. Time it for early morning. You won't need more than a jigging spoon vertical or a tube jig (smelt) most summer days.

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

The chart marks 5 structure features on Loch Trool; the deepest is Deep basin at about 47 ft.
Loch Trool is about 55 ft (17 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, arctic char on Loch Trool. 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 6 ft of water that rates prime for european perch in spring. 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.
