2,660-acre lake near Highland. The lake tops out around 282 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 1897-1909, digitized from the bathymetric atlas published in 1910. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Loch Fannich draws 2,654 acres inside 19.3 miles of shoreline. A development index of 2.7 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 31% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 6.9 mi long by 2 mi wide at the broadest reach. You'll find it in Highland. Closest neighbour on DepthScout: Loch Gorm, 3 mi northeast of here.
Come spring, look for brown trout tight to the bank in 3 to 25 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 5 to 35 ft. Start at Main-lake point. It's a point holding about 6 ft of water and rates prime come spring. Prime time lands in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (6 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Secondary point (24 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Rock reef (7 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | open water | Jigging spoon, Small stickbait (slow) |
The spring pattern is a shallow one: european perch in 3 to 12 ft. As the season builds they drop to 8 to 28 ft, wintering in 12 to 33 ft. Top water on the chart: Back-bay flat, a weed flat in the 7 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small crankbait (perch pattern) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (7 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Back-bay flat (7 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 | Back-bay flat (7 ft) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| 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 | Back-bay flat (7 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Back-bay flat (7 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (7 ft) | Tip-ups, Large jigging spoon |
Early season arctic char use the shallows, holding in 4 to 15 ft. Summer is a 20 to 60 ft game here, winter a 10 to 40 ft one. The chart's best answer is Rock reef — rock pile, 7 ft, prime for fall. Best bite is early morning. Tie on a jigging spoon vertical or a tube jig (smelt) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | Rock reef (7 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 20 to 60 ft | dawn | open water | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | Rock reef (7 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | Rock reef (7 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
Loch Fannich carries 11 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 281 ft down.
Loch Fannich is about 282 ft (86 m) deep at its deepest point. The depth data here comes from Murray & Pullar's Scottish loch survey of 1897-1909, digitized from the bathymetric atlas published in 1910.
Anglers target brown trout, european perch, northern pike, arctic char on Loch Fannich. 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.
Back-bay flat is the top-rated area: a weed flat in about 7 ft of water that rates prime for european perch in spring. Scroll up to the map for the complete spot list by 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.
