24-acre lake near Argyll and Bute. The lake tops out around 23 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. What follows comes from the same scoring engine that paints the spots above.
On the chart, Geal Loch draws 24 acres inside 0.8 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. 73% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
When the water first warms, brown trout slide up into 3 to 23 ft. Even in summer they hold at 7 to 23 ft; winter keeps them in 3 to 23 ft. Start at Break off the point. It's a drop-off holding about 10 ft of water and rates prime come summer. The feeding windows run after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 23 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 7 to 23 ft | night & dawn | Break off the point (10 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 4 to 23 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 3 to 23 ft | dawn | Break off the point (10 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: european perch sit in 3 to 12 ft that time of year. Warm water sends them out to 7 to 23 ft; cold water stacks them in 7 to 23 ft. Top water on the chart: Deep basin, a deep basin in the 20-ft range, prime in fall. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 7 to 23 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 7 to 23 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 7 to 23 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Top water on the chart: Break off the point, a drop-off in the 10-ft range, prime in fall. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| 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 (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (10 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 |
