36-acre lake near Na h-Eileanan an Iar. The lake tops out around 34 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Loch Chearsanais or Loch Kearsinnish draws 36 acres inside 2.1 miles of shoreline. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 68% of the surface on the model — that's where the groceries are. The basin spans about 0.5 mi end to end and 0.3 mi across at its widest. The water lies in Na h-Eileanan Siar. Closest neighbour on DepthScout: Loch an Eilean, 3 mi west of here.
Spring brown trout on Loch Chearsanais or Loch Kearsinnish hold shallow, usually 3 to 25 ft. They move out to 10 to 34 ft in summer and finish the year down in 5 to 34 ft. Put Deep basin first on the milk run — a deep basin near 29 ft that grades prime for summer. The feeding windows run after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).
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 | Main-lake point (9 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 10 to 34 ft chart-limited; documented 25 to 60 ft | night & dawn | Deep basin (29 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (9 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 34 ft chart-limited; documented 5 to 35 ft | dawn | Deep basin (29 ft) | Jigging spoon, Small stickbait (slow) |
In spring, european perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 12 to 33 ft for winter. Spring european perch concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Deep basin (29 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Deep basin (29 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Deep basin (29 ft) | Tungsten jig + maggots, Small balance jig |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (9 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
Come spring, look for arctic char tight to the bank in 4 to 15 ft. Expect a summer slide to 10 to 34 ft, then a winter hold in 9 to 34 ft. Start at Deep basin. It's a deep basin holding about 29 ft of water and rates prime come summer. Prime time lands in early morning. A jigging spoon vertical or a tube jig (smelt) 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 | 4 to 15 ft | midday & dawn | open water | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 10 to 34 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (29 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | open water | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 9 to 34 ft chart-limited; documented 10 to 40 ft | midday & dawn | Deep basin (29 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 29 ft.
Loch Chearsanais or Loch Kearsinnish is about 34 ft (10 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target brown trout, european perch, northern pike, arctic char on Loch Chearsanais or Loch Kearsinnish. 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 4 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.
