2,333-acre lake near Stirling. The lake tops out around 287 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. Below is the species-by-species picture, pulled from the same data the map uses.
Loch Earn maps at 2,328 acres behind 14.1 miles of shoreline. With a 2.1 development index there's bank structure worth casting at, in moderation. About 3% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 6.4 mi long by 0.9 mi wide at the broadest reach. It sits in Stirling. If the bite dies, Lochan Breaclaich is 5 mi to the north.
In spring, brown trout run shallow here, mostly 3 to 25 ft. Midsummer fish sit out in 25 to 60 ft before dropping to 5 to 35 ft for winter. Spring brown trout concentrate at Main-lake point, a prime-rated point around 16 ft. Fish it in after dark and early morning and you'll meet the bite. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (16 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Main-lake point (16 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (16 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | open water | Jigging spoon, Small stickbait (slow) |
Spring european perch on Loch Earn hold shallow, usually 3 to 12 ft. They move out to 8 to 28 ft in summer and finish the year down in 12 to 33 ft. Put Shallow bay flat first on the milk run — a feeding flat near 6 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small crankbait (perch pattern).
| 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 | 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 |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a feeding flat holding about 6 ft of water and rates prime come spring. The feeding windows run 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 | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (16 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (16 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 |
Start shallow in spring: arctic char sit in 4 to 15 ft that time of year. Summer pushes them deeper, 20 to 60 ft, and winter fish settle into 10 to 40 ft. The spot to know is Shallow bay flat, a feeding flat in about 6 ft of water that rates good for arctic char in spring. Warm-month bites cluster around early morning. Throw a jigging spoon vertical or a tube jig (smelt) until the fish tell you otherwise.
| 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 | open water | 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 |
The spring pattern is a shallow one: atlantic salmon in 5 to 30 ft. As the season builds they drop to 20 to 70 ft, wintering in 10 to 45 ft. Top water on the chart: Main-lake point, a point in the 16 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a trolling spoon or a flasher + fly gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 30 ft | dawn & dusk | Main-lake point (16 ft) | Slim coastal spoon, Trolling spoon |
| Summer | 20 to 70 ft | dawn & dusk | open water | Trolling spoon, Flasher + fly |
| Fall | 4 to 28 ft | dawn & dusk | Main-lake point (16 ft) | Casting spoon, Large streamer |
| Winter | 10 to 45 ft | midday | open water | Slow coastal spoon |
Loch Earn carries 8 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 287 ft down.
Loch Earn is about 287 ft (87 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, atlantic salmon on Loch Earn. 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 feeding flat in about 6 ft of water that rates prime for european perch in spring. The interactive chart above rates every 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.
