172-acre lake near Na h-Eileanan an Iar. The lake tops out around 17 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Loch Olaidh Meadhanach or Loch Ollay draws 172 acres inside 6.1 miles of shoreline. That shoreline is heavily fingered (development index 3.3) — bays, points and pockets everywhere, which multiplies the fishable edge. 91% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
When the water first warms, brown trout slide up into 2 to 17 ft. Summer keeps them at 5 to 17 ft, and they winter in 2 to 17 ft. If you only fish one area, make it Break off the point: a drop-off around 8 ft that scores prime in summer. In summer the feeding windows fall in after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 17 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 5 to 17 ft | night & dawn | Break off the point (8 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 3 to 17 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 2 to 17 ft | dawn | Break off the point (8 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: european perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 5 to 17 ft, and winter fish settle into 5 to 17 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for european perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 5 to 17 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 5 to 17 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 5 to 17 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 5 to 17 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 5 to 17 ft | dawn & dusk | Break off the point (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 5 to 17 ft | midday & dawn | Break off the point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
