79-acre lake near Na h-Eileanan an Iar. The lake tops out around 55 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 1904, digitized from the bathymetric atlas published in 1910. Here's the year, species by species, as the scoring engine sees it.
On the chart, Loch Crogabhat draws 79 acres inside 2.9 miles of shoreline. The 2.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Roughly 39% of the water is 15 ft or less, the band where the food chain lives. Call it 0.9 mi long by 0.4 mi wide at the broadest reach. You'll find it in Na h-Eileanan Siar. Closest neighbour on DepthScout: Loch a Ghlinne-dorcha, 1 mi southwest of here.
Come spring, look for brown trout tight to the bank in 3 to 25 ft. Expect a summer slide to 17 to 55 ft, then a winter hold in 5 to 35 ft. Start at Deep basin. It's a deep basin holding about 55 ft of water and rates prime come summer. 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.
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 | 3 to 25 ft | dawn & dusk | Secondary point (9 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 17 to 55 ft chart-limited; documented 25 to 60 ft | night & dawn | Deep basin (55 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Secondary point (9 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: Shallow bay flat, a weed flat in the 11 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 | Shallow bay flat (11 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Shallow bay flat (11 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 (12 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 11 ft range, prime in winter. 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 (11 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (11 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (11 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (11 ft) | Tip-ups, Large jigging spoon |
Early season arctic char use the shallows, holding in 4 to 15 ft. Summer is a 17 to 55 ft game here, winter a 10 to 40 ft one. The chart's best answer is Deep basin — deep basin, 55 ft, prime for summer. Best bite is early morning. Tie on a jigging spoon vertical or a tube jig (smelt) and you're in the game.
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 | 4 to 15 ft | midday & dawn | open water | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 17 to 55 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (55 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 |
5 pieces of structure are mapped here — Deep basin, around 55 ft, is the deepest of them.
Loch Crogabhat is about 55 ft (17 m) deep at its deepest point. The depth data here comes from Murray & Pullar's Scottish loch survey of 1904, digitized from the bathymetric atlas published in 1910.
Anglers target brown trout, european perch, northern pike, arctic char on Loch Crogabhat. 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 11 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.
