414-acre lake near Highland. The lake tops out around 153 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from Murray & Pullar's Scottish loch survey of 1902, digitized from the bathymetric atlas published in 1910. The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 413 acres, worked by 4.6 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. Roughly 50% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 1.6 mi with a 0.8-mi widest point. It sits in Highland. Loch na Creige Duibhe sits 2 mi west — the closest neighbouring chart.
Spring puts brown trout in skinny water — 3 to 25 ft is the zone. Warm water sends them out to 25 to 60 ft; cold water stacks them in 5 to 35 ft. Secondary point is the standout, a point at roughly 3 ft, rated prime for spring brown trout. Plan around after dark and early morning in the warm months. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Secondary point (3 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Main-lake point (31 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (31 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | open water | Jigging spoon, Small stickbait (slow) |
Early season european perch use the shallows, holding in 3 to 12 ft. Summer is an 8 to 28 ft game here, winter a 12 to 33 ft one. The chart's best answer is Shallow bay flat — weed flat, 2 ft, prime for spring. Best bite is 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 (2 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Shallow bay flat (2 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | open water | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | open water | Tungsten jig + maggots, Small balance jig |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 2 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | open water | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Secondary point (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: arctic char in 4 to 15 ft. As the season builds they drop to 20 to 60 ft, wintering in 10 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 73 ft range, good in summer. Time it for early morning. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | open water | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 20 to 60 ft | dawn | Break off the point (73 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | open water | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | open water | Jigging spoon (glow/silver), Tungsten jig + plastic |
Loch Osgaig carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 153 ft down.
Loch Osgaig is about 153 ft (47 m) deep at its deepest point. The depth data here comes from Murray & Pullar's Scottish loch survey of 1902, digitized from the bathymetric atlas published in 1910.
Anglers target brown trout, european perch, northern pike, arctic char on Loch Osgaig. 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 2 ft of water that rates prime for northern pike 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.
