23-acre lake near Highland. The lake tops out around 30 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. What the data behind the map says about each species, season by season:
The outline encloses 23 acres, worked by 1.2 miles of shoreline. With a 1.8 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 60% of this chart, as modeled. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. Highland claims this one. Loch Eilde Mór sits 1 mi southeast — the closest neighbouring chart.
In spring, brown trout run shallow here, mostly 3 to 25 ft. Summer pushes them deeper, 9 to 30 ft, and winter fish settle into 4 to 30 ft. Break off the point is the standout, a drop-off at roughly 14 ft, rated prime for summer brown trout. Time it for after dark and early morning. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| 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 chart-limited; documented 25 to 60 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 |

The summer box starts with a drop-shot micro plastics or a small crankbait (perch pattern).

When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Break off the point: a drop-off around 14 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| 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 (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 | Main-lake point (8 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: arctic char sit in 4 to 15 ft that time of year. Warm water sends them out to 9 to 30 ft; cold water stacks them in 8 to 30 ft. Top water on the chart: Deep basin, a deep basin in the 26 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a jigging spoon vertical or a tube jig (smelt) until the fish tell you otherwise.

The chart marks 3 structure features on Coire an Lochain; the deepest is Deep basin at about 26 ft.
Coire an Lochain is about 30 ft (9 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target brown trout, european perch, northern pike, arctic char on Coire an Lochain. 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.
Deep basin is the top-rated area: a deep basin in about 26 ft of water that rates prime for european perch in fall. Every other rated spot, per species and season, is on the map above.
