105-acre lake near Shetland Islands. The lake tops out around 7 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from Murray & Pullar's Scottish loch survey of 1903, digitized from the bathymetric atlas published in 1910. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 104 acres of water rimmed by 1.9 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.8 mi with a 0.4-mi widest point. You'll find it in Shetland Islands. The nearest mapped water is Loch of Clickimin, 1 mi to the northeast.
When the water first warms, brown trout slide up into 1 to 7 ft. There's no big seasonal slide here — summer means 2 to 7 ft, winter 1 to 7 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 | 1 to 7 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (2 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 (6 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 (2 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 7 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 2 to 7 ft that time of year. They don't go far with the seasons — 2 to 7 ft covers summer, 2 to 7 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 2 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 | 2 to 7 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 2 to 7 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 2 to 7 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (7 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 (7 ft) | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: northern pike in 2 to 7 ft. The depth story barely changes: 2 to 7 ft through summer, 2 to 7 ft in winter. The spot to know is Shallow bay flat, a weed flat in about 2 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.

| Winter | 2 to 7 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
The chart marks 6 structure features on Sandy Loch Reservoir; the deepest is Deep basin at about 7 ft.
Sandy Loch Reservoir is about 7 ft (2 m) deep at its deepest point. The depth data here comes from Murray & Pullar's Scottish loch survey of 1903, digitized from the bathymetric atlas published in 1910.
Anglers target brown trout, european perch, northern pike on Sandy Loch Reservoir. 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 2 ft of water that rates prime for european perch in spring. The map above holds the full rated-spot list for every 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.
