29-acre lake near Shetland Islands. The lake tops out around 45 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 29 acres, worked by 1.1 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 37% of the surface on the model — that's where the groceries are. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. Shetland Islands claims this one. Muckle Lunga Water sits 1 mi northeast — the closest neighbouring chart.
The spring pattern is a shallow one: brown trout in 3 to 25 ft. As the season builds they drop to 14 to 45 ft, wintering in 5 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 20 ft range, prime in summer. Time it for after dark and early morning. 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 (11 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 14 to 45 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (20 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (11 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (20 ft) | Jigging spoon, Small stickbait (slow) |
Come spring, look for european perch tight to the bank in 3 to 12 ft. Expect a summer slide to 8 to 28 ft, then a winter hold in 12 to 33 ft. Start at Break off the point. It's a drop-off holding about 20 ft of water and rates prime come summer. Prime time lands in 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 | open water | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Break off the point (20 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Break off the point (20 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Deep basin (38 ft) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Break off the point first on the milk run — a drop-off near 20 ft that grades prime for summer. In summer the feeding windows fall in 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 | open water | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (20 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (11 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Main-lake point (11 ft) | Tip-ups, Large jigging spoon |
In spring, arctic char run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 14 to 45 ft before dropping to 10 to 40 ft for winter. Summer arctic char concentrate at Deep basin, a prime-rated deep basin around 38 ft. Fish it in early morning and you'll meet the bite. You won't need more than a jigging spoon vertical or a tube jig (smelt) most summer days.
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 | Break off the point (20 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 14 to 45 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (38 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (20 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | Deep basin (38 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
Count 4 structure marks on this chart. The deepest, Deep basin, sits near 38 ft.
Birka Water is about 45 ft (14 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 Birka Water. 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 38 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.
