69-acre lake near Highland. The lake tops out around 18 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Loch an Lagain maps at 69 acres behind 2.3 miles of shoreline. With a 1.9 development index there's bank structure worth casting at, in moderation. About 86% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 1 mi long by 0.2 mi wide at the broadest reach. Highland claims this one. Its nearest charted neighbour, Loch Buidhe, is 2 mi to the north.
Spring puts brown trout in skinny water — 2 to 18 ft is the zone. Summer fish stay in 5 to 18 ft, and winter fish hold in 3 to 18 ft. Summer brown trout concentrate at Break off the point, a prime-rated drop-off around 8 ft. Warm-month bites cluster around after dark and early morning. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
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 | 2 to 18 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 5 to 18 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (8 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 3 to 18 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 3 to 18 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (8 ft) | Jigging spoon, Small stickbait (slow) |
Early season european perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 5 to 18 ft, then a winter hold in 5 to 18 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small crankbait (perch pattern) and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 5 to 18 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 5 to 18 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 5 to 18 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + maggots, Small balance jig |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 5 to 18 ft, then a winter hold in 5 to 15 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

6 pieces of structure are mapped here — Deep basin, around 15 ft, is the deepest of them.
Loch an Lagain is about 18 ft (5 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 on Loch an Lagain. 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.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for european perch in spring. Every other rated spot, per species and season, is on the map above.
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.
