201-acre lake near North Ayrshire. The lake tops out around 30 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Kilbirnie Loch runs 200 acres with 3.1 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Roughly 76% of the water is 15 ft or less as modeled, the band where the food chain lives.
Early season brown trout use the shallows, holding in 3 to 25 ft. Summer is a 9 to 30 ft game here, winter a 4 to 30 ft one. The chart's best answer is Break off the point — drop-off, 14 ft, prime for summer. Best bite is after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.
| 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 | 9 to 30 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 | 4 to 30 ft | dawn | Break off the point (14 ft) | Jigging spoon, Small stickbait (slow) |
Spring puts european perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 8 to 28 ft; cold water stacks them in 9 to 30 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring european perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
| 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 | Deep basin (26 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 9 to 30 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (26 ft) | Tungsten jig + maggots, Small balance jig |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| 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 (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 | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
When the water first warms, arctic char slide up into 4 to 15 ft. By summer they slide out to 9 to 30 ft, and by winter most fish are in 8 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 26 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a jigging spoon vertical or a tube jig (smelt) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | Break off the point (14 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 9 to 30 ft | dawn | Deep basin (26 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (14 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 8 to 30 ft | midday & dawn | Deep basin (26 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
