6-acre lake near Wiltshire. The lake tops out around 13 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. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Fonthill Lake runs 6 acres with 0.4 miles of edge. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. The water lies in Wiltshire. Closest neighbour on DepthScout: Shear Water, 9 mi northwest of here.
When the water first warms, brown trout slide up into 2 to 13 ft. There's no big seasonal slide here — summer means 4 to 13 ft, winter 2 to 13 ft. Start at Break off the point. It's a drop-off holding about 6 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 | 2 to 13 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 | 4 to 13 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (6 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 2 to 13 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 2 to 13 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (6 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: european perch sit in 3 to 12 ft that time of year. Warm water sends them out to 4 to 13 ft; cold water stacks them in 4 to 13 ft. Top water on the chart: Deep basin, a deep basin in the 11 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 | 3 to 12 ft | midday & dawn | Break off the point (6 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 |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 4 to 13 ft, wintering in 4 to 13 ft. Top water on the chart: Break off the point, a drop-off in the 6 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.

| Spring | 2 to 8 ft | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |
| Summer | 4 to 13 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 13 ft chart-limited; documented 6 to 18 ft | midday & dawn | Break off the point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 13 ft chart-limited; documented 5 to 15 ft | midday | Main-lake point (8 ft) | Tip-ups, Large jigging spoon |
3 pieces of structure are mapped here — Deep basin, around 11 ft, is the deepest of them.
Fonthill Lake 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 Fonthill 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 11 ft of water that rates prime for european perch in fall. The interactive chart above rates every 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.
