25-acre lake near Northumberland. The lake tops out around 6 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Here is how the season plays out for each species, straight from the data behind the map.
Crag Lough maps at 25 acres behind 1.1 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. 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 0.5 mi. Northumberland claims this one. If the bite dies, Greenlee Lough is 1 mi to the north.
In spring, brown trout run shallow here, mostly 1 to 6 ft. Summer keeps them at 2 to 6 ft, and they winter in 1 to 6 ft. Break off the point is the standout, a drop-off at roughly 3 ft, rated prime for summer brown trout. Time it for after dark and early morning. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.
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) |
Spring european perch on Crag Lough hold shallow, usually 2 to 6 ft. Depth-wise the year is flat: 2 to 6 ft in summer, 2 to 6 ft once it turns cold. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small crankbait (perch pattern).
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 | Shallow bay flat (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 |
When the water first warms, northern pike slide up into 2 to 6 ft. There's no big seasonal slide here — summer means 2 to 6 ft, winter 2 to 6 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

4 pieces of structure are mapped here — Main-lake point, around 6 ft, is the deepest of them.
Crag Lough 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 Crag Lough. 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. 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.
