7-acre lake near Na h-Eileanan an Iar. The lake tops out around 7 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. What the data behind the map says about each species, season by season:
Drawn out, this is 7 acres of water rimmed by 0.5 miles of bank. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The water lies in Na h-Eileanan Siar. The nearest mapped water is Loch Aird an Sgairbh, 2 mi to the north.
Spring brown trout on Loch na Cuithe Mòire hold shallow, usually 1 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 1 to 7 ft once it turns cold. Put Break off the point first on the milk run — a drop-off near 3 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 | 1 to 7 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (7 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 2 to 7 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (3 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 1 to 7 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (7 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 7 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (3 ft) | Jigging spoon, Small stickbait (slow) |
In spring, european perch run shallow here, mostly 2 to 7 ft. Summer keeps them at 2 to 7 ft, and they winter in 2 to 7 ft. Fall european perch concentrate at Deep basin, a prime-rated deep basin around 6 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 | 2 to 7 ft chart-limited; documented 3 to 12 ft | midday & dawn | Break off the point (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 2 to 7 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 2 to 7 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (6 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 2 to 7 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (6 ft) | Tungsten jig + maggots, Small balance jig |
In spring, northern pike run shallow here, mostly 2 to 7 ft. Summer keeps them at 2 to 7 ft, and they winter in 2 to 7 ft. Break off the point is the standout, a drop-off at roughly 3 ft, rated prime for fall 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 7 ft chart-limited; documented 2 to 8 ft | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 7 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (3 ft) | Bucktail, Weedless spoon over cabbage |

| Winter | 2 to 7 ft chart-limited; documented 5 to 15 ft | midday | Main-lake point (7 ft) | Tip-ups, Large jigging spoon |
Structure-wise the chart holds 3 features, led in depth by Main-lake point at roughly 7 ft.
Loch na Cuithe Mòire is about 7 ft (2 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 on Loch na Cuithe Mòire. 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.
Deep basin is the top-rated area: a deep basin in about 6 ft of water that rates prime for european perch in fall. 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.
