5-acre lake near Argyll and Bute. The lake tops out around 30 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 nan Ròn runs 5 acres with 0.4 miles of edge. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. Roughly 58% of the water is 15 ft or less as modeled, the band where the food chain lives. You'll find it in Argyll and Bute. The nearest mapped water is unnamed, 6 mi to the north.
When the water first warms, brown trout slide up into 3 to 25 ft. By summer they slide out to 9 to 30 ft, and by winter most fish are in 4 to 30 ft. If you only fish one area, make it Shoreline break: a drop-off around 14 ft that scores prime in summer. In summer the feeding windows fall in after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.
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 | Shoreline break (14 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 9 to 30 ft chart-limited; documented 25 to 60 ft | night & dawn | Shoreline break (14 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Shoreline break (14 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 30 ft chart-limited; documented 5 to 35 ft | dawn | Shoreline break (14 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: european perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 8 to 28 ft, and winter fish settle into 9 to 30 ft. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for european perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 9 to 30 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 9 to 30 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (26 ft) | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline break (14 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shoreline break (14 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
Spring arctic char on Loch nan Ròn hold shallow, usually 4 to 15 ft. They move out to 9 to 30 ft in summer and finish the year down in 8 to 30 ft. Put Deep basin first on the milk run — a deep basin near 26 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a jigging spoon vertical or a tube jig (smelt).

Loch nan Ròn is about 30 ft (9 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 nan Ròn. 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 4 ft of water that rates prime for european perch in spring. 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.
