101-acre lake near Conwy. The lake tops out around 72 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Species by species, here's what the data says the year looks like.
On the chart, Llyn Conwy draws 101 acres inside 2 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 41% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 0.6 mi with a 0.5-mi widest point. The water lies in Conwy. Closest neighbour on DepthScout: Llyn Gamallt Fach, 2 mi southwest of here.
Spring brown trout on Llyn Conwy hold shallow, usually 3 to 25 ft. They move out to 25 to 60 ft in summer and finish the year down in 5 to 35 ft. Put Break off the point first on the milk run — a drop-off near 32 ft that grades prime for summer. The feeding windows run after dark and early morning.

In spring, european perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 12 to 33 ft for winter. Spring european perch concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Fish it in early morning and you'll meet the bite. 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 | Shallow bay flat (6 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |

Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring northern pike. Time it for early morning and the evening. 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 | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |

Come spring, look for arctic char tight to the bank in 4 to 15 ft. Expect a summer slide to 20 to 60 ft, then a winter hold in 10 to 40 ft. Start at Deep basin. It's a deep basin holding about 61 ft of water and rates prime come summer. Prime time lands in early morning. A jigging spoon vertical or a tube jig (smelt) is the honest summer answer here.
| 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 | 20 to 60 ft | dawn | Deep basin (61 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (32 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | Break off the point (32 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
