11-acre lake near Gwynedd. The lake tops out around 32 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 11 acres, worked by 0.5 miles of shoreline. Nearly circular (index 1.2), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 36% of this chart, as modeled. It sits in Gwynedd. Llyn Eigiau Reservoir sits 3 mi southeast — the closest neighbouring chart.
Spring puts brown trout in skinny water — 3 to 25 ft is the zone. Warm water sends them out to 10 to 32 ft; cold water stacks them in 5 to 32 ft. Break off the point is the standout, a drop-off at roughly 14 ft, rated prime for summer brown trout. Plan around after dark and early morning in the warm months. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
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 (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 10 to 32 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (14 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 32 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (14 ft) | Jigging spoon, Small stickbait (slow) |
Early season european perch use the shallows, holding in 3 to 12 ft. Summer is an 8 to 28 ft game here, winter a 10 to 32 ft one. The chart's best answer is Deep basin — deep basin, 27 ft, prime for fall. Best bite is early morning. Tie on a drop-shot micro plastics or a small crankbait (perch pattern) and you're in the game.

Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Break off the point: a drop-off around 14 ft that scores prime in fall. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| 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 (14 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (14 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Main-lake point (8 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: arctic char in 4 to 15 ft. As the season builds they drop to 10 to 32 ft, wintering in 8 to 32 ft. Top water on the chart: Deep basin, a deep basin in the 27 ft range, prime in summer. Time it for early morning. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.

The chart marks 3 structure features on Llyn Anafon; the deepest is Deep basin at about 27 ft.
Llyn Anafon is about 32 ft (10 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 Llyn Anafon. 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 27 ft of water that rates prime for european perch in fall. Open the map above to see every rated 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.
