19-acre lake near Argyll and Bute. The lake tops out around 20 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Loch a Chaorainn runs 19 acres with 0.8 miles of edge. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 85% of the surface on the model — that's where the groceries are. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. You'll find it in Argyll and Bute. For a second option, Loch Dubh-mór lies 1 mi northeast.
Come spring, look for brown trout tight to the bank in 2 to 20 ft. Through summer count on 6 to 20 ft; the winter hold is 3 to 20 ft. Start at Break off the point. It's a drop-off holding about 9 ft of water and rates prime come summer. Prime time lands in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
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 | 2 to 20 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 | 6 to 20 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (9 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 3 to 20 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 3 to 20 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (9 ft) | Jigging spoon, Small stickbait (slow) |
The spring pattern is a shallow one: european perch in 3 to 12 ft. As the season builds they drop to 6 to 20 ft, wintering in 6 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small crankbait (perch pattern) 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 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 6 to 20 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (17 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 6 to 20 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (17 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 6 to 20 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (17 ft) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (9 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 17 ft.
Loch a Chaorainn is about 20 ft (6 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 a Chaorainn. 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 3 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.
