7-acre lake near Hertfordshire. The lake tops out around 8 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 7 acres of water rimmed by 0.7 miles of bank. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. You'll find it in Hertfordshire. For a second option, North Metropolitan pit lies 7 mi southwest.
Spring brown trout on Bonnington Lake hold shallow, usually 1 to 8 ft. Depth-wise the year is flat: 2 to 8 ft in summer, 1 to 8 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 7 ft, prime for summer. Prime time lands in after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).
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 8 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 2 to 8 ft chart-limited; documented 25 to 60 ft | night & dawn | Deep basin (7 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 1 to 8 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 8 ft chart-limited; documented 5 to 35 ft | dawn | Deep basin (7 ft) | Jigging spoon, Small stickbait (slow) |
In spring, european perch run shallow here, mostly 2 to 8 ft. Summer keeps them at 2 to 8 ft, and they winter in 2 to 8 ft. Deep basin is the standout, a deep basin at roughly 7 ft, rated prime for fall european perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft chart-limited; documented 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 2 to 8 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 2 to 8 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (7 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 2 to 8 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (7 ft) | Tungsten jig + maggots, Small balance jig |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer keeps them at 2 to 8 ft, and they winter in 2 to 8 ft. Fall northern pike concentrate at Main-lake point, a prime-rated point around 8 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |

| Winter | 2 to 8 ft chart-limited; documented 5 to 15 ft | midday | Main-lake point (8 ft) | Tip-ups, Large jigging spoon |
Structure-wise the chart holds 2 features, led in depth by Main-lake point at roughly 8 ft.
Bonnington Lake is about 8 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 Bonnington Lake. 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 7 ft of water that rates prime for european perch in fall. 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.
