Fishing Loch Sloy: what the data says
311-acre lake near Argyll and Bute. The lake tops out around 31 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What follows comes from the same scoring engine that paints the spots above.
On the chart, Loch Sloy draws 311 acres inside 4.5 miles of shoreline. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. Roughly 84% of the water is 15 ft or less as modeled, the band where the food chain lives.
Brown Trout fishing at Loch Sloy
Come spring, look for brown trout tight to the bank in 3 to 25 ft. They move out to 9 to 31 ft in summer and finish the year down in 4 to 31 ft. If you only fish one area, make it Break off the point: a drop-off around 14 ft that scores prime in summer. Best bite is after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.

|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for european perch in spring. Plan around early morning in the warm months.

The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for northern pike in spring. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
