7-acre lake near Na h-Eileanan an Iar. The lake tops out around 7 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Loch Airigh na h-Achlais draws 7 acres inside 0.4 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory.
Come spring, look for brown trout tight to the bank in 1 to 7 ft. There's no big seasonal slide here — summer means 2 to 7 ft, winter 1 to 7 ft. Start at Shoreline break. It's a drop-off holding about 3 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft | dawn & dusk | Shoreline break (3 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 2 to 7 ft | night & dawn | Shoreline break (3 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 1 to 7 ft | dusk & dawn | Shoreline break (3 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 7 ft | dawn | Shoreline break (3 ft) | Jigging spoon, Small stickbait (slow) |
The spring pattern is a shallow one: european perch in 2 to 7 ft. Summer keeps them at 2 to 7 ft, and they winter in 2 to 7 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3-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 | 2 to 7 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 2 to 7 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 2 to 7 ft | midday | Deep basin (6 ft) | Jigging spoon (small), Drop-shot on deep flats |

Start shallow in spring: northern pike sit in 2 to 7 ft that time of year. Summer fish stay in 2 to 7 ft, and winter fish hold in 2 to 7 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3-ft range, prime in spring. 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 7 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
