174-acre lake near Perth and Kinross. The lake tops out around 58 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 173 acres of water rimmed by 2.5 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. Roughly 18% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 0.9 mi with a 0.5-mi widest point. The water lies in Perth and Kinross. The nearest mapped water is Rae Loch, 1 mi to the east.
Early season brown trout use the shallows, holding in 3 to 25 ft. Summer is a 17 to 58 ft game here, winter a 5 to 35 ft one. The chart's best answer is Break off the point — drop-off, 26 ft, prime for summer. Best bite is after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.
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 | 3 to 25 ft | dawn & dusk | Main-lake point (15 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 17 to 58 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (26 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (15 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (26 ft) | Jigging spoon, Small stickbait (slow) |
Spring puts european perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 8 to 28 ft; cold water stacks them in 12 to 33 ft. Break off the point is the standout, a drop-off at roughly 26 ft, rated prime for summer european perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Break off the point (26 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Break off the point (26 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Break off the point (26 ft) | Tungsten jig + maggots, Small balance jig |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated feeding flat around 6 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (15 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (15 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
When the water first warms, arctic char slide up into 4 to 15 ft. By summer they slide out to 17 to 58 ft, and by winter most fish are in 10 to 40 ft. If you only fish one area, make it Deep basin: a deep basin around 49 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a jigging spoon vertical or a tube jig (smelt) rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | Shallow bay flat (6 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 17 to 58 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (49 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (26 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | Break off the point (26 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
Count 6 structure marks on this chart. The deepest, Deep basin, sits near 49 ft.
Loch of Drumellie or Marlee Loch is about 58 ft (18 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, arctic char on Loch of Drumellie or Marlee 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 49 ft of water that rates prime for arctic char in summer. Scroll up to the map for the complete spot list by 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.
