4-acre lake near Durham. The lake tops out around 6 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Lochnaw runs 4 acres with 0.4 miles of edge. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The water lies in County Durham. Closest neighbour on DepthScout: Derwent Reservoir, 21 mi northwest of here.
When the water first warms, brown trout slide up into 1 to 6 ft. There's no big seasonal slide here — summer means 2 to 6 ft, winter 1 to 6 ft. Start at Break off the point. It's a drop-off holding about 3 ft of water and rates prime come summer. The feeding windows run 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 6 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (6 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 2 to 6 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (3 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 1 to 6 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (6 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 6 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (3 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: european perch sit in 2 to 6 ft that time of year. They don't go far with the seasons — 2 to 6 ft covers summer, 2 to 6 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 5 ft range, prime in fall. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.
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 6 ft chart-limited; documented 3 to 12 ft | midday & dawn | Break off the point (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 2 to 6 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 2 to 6 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 2 to 6 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: northern pike in 2 to 6 ft. The depth story barely changes: 2 to 6 ft through summer, 2 to 6 ft in winter. Top water on the chart: Break off the point, a drop-off in the 3 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
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 6 ft chart-limited; documented 2 to 8 ft | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 6 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 6 ft chart-limited; documented 6 to 18 ft | midday & dawn | Break off the point (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 6 ft chart-limited; documented 5 to 15 ft | midday | Main-lake point (6 ft) | Tip-ups, Large jigging spoon |
3 pieces of structure are mapped here — Main-lake point, around 6 ft, is the deepest of them.
Lochnaw is about 6 ft (2 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 Lochnaw. 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 5 ft of water that rates prime for european perch in fall. 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.
