116-acre lake near Highland. The lake tops out around 85 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Loch Cuaich runs 115 acres with 2.1 miles of edge. Nearly circular (index 1.4), so the story is the bottom, not the bank. About 13% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 0.9 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Highland. For a second option, Loch an t-Seilich lies 4 mi east.
When the water first warms, brown trout slide up into 3 to 25 ft. Summer is a 25 to 60 ft game here, winter a 5 to 35 ft one. Start at Break off the point. It's a drop-off holding about 38 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 25 ft | dawn & dusk | Main-lake point (21 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Break off the point (38 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (21 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (38 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 8 to 28 ft; cold water stacks them in 12 to 33 ft. Top water on the chart: Shallow bay flat, a feeding flat in the 6 ft range, prime in spring. 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 | 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) |
| Fall | 10 to 33 ft | midday | Break off the point (38 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Break off the point (38 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: Shallow bay flat, a feeding flat in the 6 ft range, prime in spring. 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 | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (21 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
Spring arctic char on Loch Cuaich hold shallow, usually 4 to 15 ft. By summer they slide out to 20 to 60 ft, and by winter most fish are in 10 to 40 ft. The chart's best answer is Break off the point — drop-off, 38 ft, prime for summer. Prime time lands in early morning. The summer box starts with a jigging spoon vertical or a tube jig (smelt).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | Shallow bay flat (6 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 20 to 60 ft | dawn | Break off the point (38 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (38 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | Break off the point (38 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |

Anglers target brown trout, european perch, northern pike, arctic char on Loch Cuaich. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Break off the point is the top-rated area: a drop-off in about 38 ft of water that rates prime for brown trout in summer. Open the map above to see every rated spot for each species and season.
For brown trout, the summer bite is best in after dark and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
