28-acre lake near Argyll and Bute. The lake tops out around 114 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 28 acres wrapped in 0.9 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 7% of this chart, as modeled. The basin spans about 0.3 mi end to end and 0.3 mi across at its widest. Argyll and Bute claims this one. Its nearest charted neighbour, Loch a Chaorainn, is 1 mi to the southwest.
Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Summer pushes them deeper, 25 to 60 ft, and winter fish settle into 5 to 35 ft. The spot to know is Break off the point, a drop-off in about 51 ft of water that rates prime for brown trout in summer. Warm-month bites cluster around after dark and early morning. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (29 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Break off the point (51 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (29 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | open water | Jigging spoon, Small stickbait (slow) |
When the water first warms, european perch slide up into 3 to 12 ft. By summer they slide out to 8 to 28 ft, and by winter most fish are in 12 to 33 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 6 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small crankbait (perch pattern) rigged through the warm months.
| 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 |
Spring northern pike on Loch Dubh-mór hold shallow, usually 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Shallow bay flat — feeding flat, 6 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| 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 |
Spring puts arctic char in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 20 to 60 ft; cold water stacks them in 10 to 40 ft. Break off the point is the standout, a drop-off at roughly 51 ft, rated prime for summer arctic char. Plan around early morning in the warm months. A jigging spoon vertical or a tube jig (smelt) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | Shallow bay flat (6 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 20 to 60 ft | dawn | Break off the point (51 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 | Break off the point (51 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
4 pieces of structure are mapped here — Deep basin, around 97 ft, is the deepest of them.
Loch Dubh-mór is about 114 ft (35 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 Dubh-mór. 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.
Break off the point is the top-rated area: a drop-off in about 51 ft of water that rates prime for brown trout in summer. The interactive chart above rates every 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.
