25-acre lake near Conwy. The lake tops out around 36 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Llyn y Parc runs 25 acres with 1.4 miles of edge. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. 61% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
Spring brown trout on Llyn y Parc hold shallow, usually 3 to 25 ft. By summer they slide out to 11 to 36 ft, and by winter most fish are in 5 to 35 ft. The chart's best answer is Break off the point — drop-off, 16 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).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (9 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 11 to 36 ft | night & dawn | Break off the point (16 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (9 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (16 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. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring 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 | Shallow bay flat (4 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Break off the point (16 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Deep basin (31 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Deep basin (31 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. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 4 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 | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (16 ft) | Bucktail, Weedless spoon over cabbage |

Come spring, look for arctic char tight to the bank in 4 to 15 ft. They move out to 11 to 36 ft in summer and finish the year down in 9 to 36 ft. If you only fish one area, make it Deep basin: a deep basin around 31 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | Break off the point (16 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 11 to 36 ft | dawn | Deep basin (31 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (16 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 9 to 36 ft | midday & dawn | Deep basin (31 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
