20-acre lake near Dumfries and Galloway. The lake tops out around 13 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.
Drawn out, this is 20 acres of water rimmed by 0.7 miles of bank. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. 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 0.3 mi. You'll find it in Dumfries and Galloway. For a second option, Castle Loch lies 1 mi north.
Early season brown trout use the shallows, holding in 2 to 13 ft. Even in summer they hold at 4 to 13 ft; winter keeps them in 2 to 13 ft. Put Shoreline break first on the milk run — a drop-off near 6 ft that grades prime for summer. In summer the feeding windows fall in 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 | 2 to 13 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Shoreline break (6 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 4 to 13 ft chart-limited; documented 25 to 60 ft | night & dawn | Shoreline break (6 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 2 to 13 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Shoreline break (6 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 2 to 13 ft chart-limited; documented 5 to 35 ft | dawn | Shoreline break (6 ft) | Jigging spoon, Small stickbait (slow) |
Spring puts european perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 4 to 13 ft, wintering in 4 to 13 ft. Spring european perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. 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 (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 4 to 13 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (11 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 4 to 13 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (11 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 4 to 13 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (11 ft) | Tungsten jig + maggots, Small balance jig |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 4 to 13 ft; cold water stacks them in 4 to 13 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.

4 pieces of structure are mapped here — Deep basin, around 11 ft, is the deepest of them.
Hightae Mill Loch is about 13 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 Hightae Mill 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.
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. 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.
