19-acre lake near City of Edinburgh. The lake tops out around 10 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Duddingston Loch runs 18 acres with 0.8 miles of edge. The basin is a simple one (shoreline index 1.3) — 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. End to end it runs roughly 0.3 mi. The water lies in City of Edinburgh. For a second option, Harlaw Reservoir lies 8 mi southwest.
Spring brown trout on Duddingston Loch hold shallow, usually 1 to 10 ft. Depth-wise the year is flat: 3 to 10 ft in summer, 1 to 10 ft once it turns cold. Put Break off the point first on the milk run — a drop-off near 5 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 10 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 | 3 to 10 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (5 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 2 to 10 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 10 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (5 ft) | Jigging spoon, Small stickbait (slow) |
In spring, european perch run shallow here, mostly 3 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 3 to 10 ft. Fall european perch concentrate at Deep basin, a prime-rated deep basin around 9 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 | 3 to 10 ft chart-limited; documented 3 to 12 ft | midday & dawn | Break off the point (5 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 3 to 10 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (9 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 3 to 10 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 3 to 10 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (9 ft) | Tungsten jig + maggots, Small balance jig |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 3 to 10 ft, and winter fish settle into 3 to 10 ft. Break off the point is the standout, a drop-off at roughly 5 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 8 ft | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |

Start shallow in spring: common carp sit in 2 to 10 ft that time of year. They don't go far with the seasons — 2 to 10 ft covers summer, 3 to 10 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 9 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite.

3 pieces of structure are mapped here — Deep basin, around 9 ft, is the deepest of them.
Duddingston Loch is about 10 ft (3 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, common carp on Duddingston Loch. 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 9 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.
