34-acre lake near Leicestershire. The lake tops out around 5 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 follows comes from the same scoring engine that paints the spots above.
On the chart, Groby Pool draws 34 acres inside 0.9 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 0.3 mi long by 0.3 mi wide at the broadest reach. You'll find it in Leicestershire. Closest neighbour on DepthScout: Cropston Reservoir, 2 mi northeast of here.
Come spring, look for brown trout tight to the bank in 1 to 5 ft. Through summer count on 2 to 5 ft; the winter hold is 1 to 5 ft. Start at Break off the point. It's a drop-off holding about 2 ft of water and rates good come summer. Prime time lands in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
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 5 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (5 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 2 to 5 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (2 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 1 to 5 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (5 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 5 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (2 ft) | Jigging spoon, Small stickbait (slow) |
The spring pattern is a shallow one: european perch in 1 to 5 ft. The depth story barely changes: 1 to 5 ft through summer, 2 to 5 ft in winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small crankbait (perch pattern) 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 | 1 to 5 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 1 to 5 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (4 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 2 to 5 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (4 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 2 to 5 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (4 ft) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: northern pike sit in 1 to 5 ft that time of year. They don't go far with the seasons — 2 to 5 ft covers summer, 2 to 5 ft covers winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.

Structure-wise the chart holds 4 features, led in depth by Main-lake point at roughly 5 ft.
Groby Pool is about 5 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 Groby Pool. 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.
