2,433-acre lake near Orkney Islands. The lake tops out around 14 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. What the data behind the map says about each species, season by season:
Drawn out, this is 2,428 acres of water rimmed by 18.8 miles of bank. With a shoreline index of 2.7, this water is all arms and coves — edge habitat well beyond its acreage. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 4.8 mi of water from one end to the other, 2 mi at the beam. You'll find it in Orkney Islands. For a second option, Loch of Stenness lies 2 mi south.
When the water first warms, brown trout slide up into 2 to 14 ft. There's no big seasonal slide here — summer means 4 to 14 ft, winter 2 to 14 ft. If you only fish one area, make it Break off the point: a drop-off around 6 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.
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 | 2 to 14 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 4 to 14 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (6 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 2 to 14 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 2 to 14 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (6 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, 4 to 14 ft, and winter fish settle into 4 to 14 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 | 4 to 14 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (12 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 4 to 14 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (12 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 4 to 14 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (12 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 4 to 14 ft before dropping to 4 to 14 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.

Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 12 ft.
Loch of Harray is about 14 ft (4 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 of Harray. 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 3 ft of water that rates prime for european perch in spring. Open the map above to see every rated 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.
