5-acre lake near Cumbria. The lake tops out around 48 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Bowscale Tarn draws 5 acres inside 0.4 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 26% of this chart, as modeled. You'll find it in Cumbria. For a second option, Over Water lies 6 mi northwest.
Spring brown trout on Bowscale Tarn hold shallow, usually 3 to 25 ft. By summer they slide out to 14 to 48 ft, and by winter most fish are in 5 to 35 ft. The chart's best answer is Break off the point — drop-off, 22 ft, prime for summer. Prime time lands in after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).
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 (12 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 14 to 48 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (22 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (12 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (22 ft) | Jigging spoon, Small stickbait (slow) |
In spring, european perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 28 ft, and winter fish settle into 12 to 33 ft. Break off the point is the standout, a drop-off at roughly 22 ft, rated prime for summer european perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Break off the point (22 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Break off the point (22 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Break off the point (22 ft) | Tungsten jig + maggots, Small balance jig |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Fall northern pike concentrate at Main-lake point, a prime-rated point around 12 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (12 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (12 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Main-lake point (12 ft) | Tip-ups, Large jigging spoon |
Come spring, look for arctic char tight to the bank in 4 to 15 ft. They move out to 14 to 48 ft in summer and finish the year down in 10 to 40 ft. If you only fish one area, make it Deep basin: a deep basin around 41 ft that scores prime in summer. Best bite is early morning. A jigging spoon vertical or a tube jig (smelt) 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 | 4 to 15 ft | midday & dawn | open water | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 14 to 48 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (41 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (22 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | Deep basin (41 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
3 pieces of structure are mapped here — Deep basin, around 41 ft, is the deepest of them.
Bowscale Tarn is about 48 ft (15 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 Bowscale Tarn. 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 41 ft of water that rates prime for arctic char in summer. 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.
