69-acre lake near Isle of Anglesey. The lake tops out around 9 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What the data behind the map says about each species, season by season:
Llyn Coron maps at 69 acres behind 1.6 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.5 mi with a 0.4-mi widest point. It sits in Isle of Anglesey. Its nearest charted neighbour, Llyn Penrhyn, is 6 mi to the northwest.
Start shallow in spring: brown trout sit in 1 to 9 ft that time of year. They don't go far with the seasons — 3 to 9 ft covers summer, 1 to 9 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 4 ft range, prime in summer. Fish it in after dark and early morning and you'll meet the bite. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.
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 | 1 to 9 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 | 3 to 9 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (4 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 2 to 9 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 9 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (4 ft) | Jigging spoon, Small stickbait (slow) |
When the water first warms, european perch slide up into 2 to 9 ft. There's no big seasonal slide here — summer means 3 to 9 ft, winter 3 to 9 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small crankbait (perch pattern) rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 3 to 9 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (8 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 3 to 9 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (8 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 3 to 9 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (8 ft) | Tungsten jig + maggots, Small balance jig |
Spring northern pike on Llyn Coron hold shallow, usually 2 to 8 ft. They move out to 3 to 9 ft in summer and finish the year down in 3 to 9 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.

| 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 | 3 to 9 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |

| Winter | 3 to 9 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Structure-wise the chart holds 6 features, led in depth by Main-lake point at roughly 8 ft.
Llyn Coron is about 9 ft (3 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 Llyn Coron. 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. The map above holds the full rated-spot list for every 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.
