165-acre lake near Perth and Kinross. The lake tops out around 64 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. Species by species, here's what the data says the year looks like.
On the chart, Loch Benachally draws 165 acres inside 2.7 miles of shoreline. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. 38% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 1 mi of water from one end to the other, 0.5 mi at the beam. The water lies in Perth and Kinross. The nearest mapped water is Loch Ordie, 2 mi to the west.
Come spring, look for brown trout tight to the bank in 3 to 25 ft. They move out to 25 to 60 ft in summer and finish the year down in 5 to 35 ft. If you only fish one area, make it Break off the point: a drop-off around 14 ft that scores prime in winter. Best bite is 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 (2 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Deep basin (64 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (2 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (14 ft) | Jigging spoon, Small stickbait (slow) |
The spring pattern is a shallow one: european perch in 3 to 12 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 12 to 33 ft for winter. The spot to know is Back-bay flat, a weed flat in about 4 ft of water that rates prime for european perch in spring. Plan around early morning in the warm months. 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 (4 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Break off the point (14 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Break off the point (14 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Break off the point (14 ft) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for northern pike in spring. Warm-month bites cluster around early morning and the evening. 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 | 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 | Back-bay flat (4 ft) | Tip-ups, Large jigging spoon |
Early season arctic char use the shallows, holding in 4 to 15 ft. Expect a summer slide to 20 to 60 ft, then a winter hold in 10 to 40 ft. Put Deep basin first on the milk run — a deep basin near 64 ft that grades prime for summer. In summer the feeding windows fall in 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 | Break off the point (14 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 20 to 60 ft | dawn | Deep basin (64 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (14 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | Break off the point (14 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
6 pieces of structure are mapped here — Deep basin, around 64 ft, is the deepest of them.
Loch Benachally is about 64 ft (20 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 Benachally. 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 4 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.
