227-acre lake near Somerset. The lake tops out around 19 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. The season-by-season read for each species follows, from the map's own numbers.
Cheddar Reservoir maps at 226 acres behind 2.2 miles of shoreline. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. About 79% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 0.7 mi of water from one end to the other, 0.7 mi at the beam. Somerset claims this one. If the bite dies, Blagdon Lake is 6 mi to the northeast.
The spring pattern is a shallow one: brown trout in 2 to 19 ft. The depth story barely changes: 6 to 19 ft through summer, 3 to 19 ft in winter. Top water on the chart: Break off the point, a drop-off in the 9 ft range, prime in summer. Time it for after dark and early morning. Summer baits: a spoon at the thermocline or a deep stickbait (night) 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 19 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 | 6 to 19 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (9 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 3 to 19 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 3 to 19 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (9 ft) | Jigging spoon, Small stickbait (slow) |
Come spring, look for european perch tight to the bank in 3 to 12 ft. Expect a summer slide to 5 to 19 ft, then a winter hold in 6 to 19 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 5 to 19 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (16 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 6 to 19 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (16 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 6 to 19 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (16 ft) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 6 to 19 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.

The chart marks 6 structure features on Cheddar Reservoir; the deepest is Deep basin at about 16 ft.
Cheddar Reservoir is about 19 ft (6 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 Cheddar Reservoir. 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. 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.
