5-acre lake near Somerset. The lake tops out around 7 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What the data behind the map says about each species, season by season:
The outline encloses 5 acres, worked by 0.6 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Somerset claims this one. If the bite dies, Wimbleball Lake is 12 mi to the west.
The spring pattern is a shallow one: brown trout in 1 to 7 ft. The depth story barely changes: 2 to 7 ft through summer, 1 to 7 ft in winter. Top water on the chart: Break off the point, a drop-off in the 3 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 | 1 to 7 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (7 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 2 to 7 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 7 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (7 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 7 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (3 ft) | Jigging spoon, Small stickbait (slow) |
Come spring, look for european perch tight to the bank in 2 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 2 to 7 ft. Start at Deep basin. It's a deep basin holding about 6 ft of water and rates prime come fall. Prime time lands in early morning. A drop-shot micro plastics or a small crankbait (perch pattern) 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 | 2 to 7 ft chart-limited; documented 3 to 12 ft | midday & dawn | Break off the point (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 2 to 7 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 2 to 7 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (6 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 2 to 7 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (6 ft) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 2 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 2 to 7 ft. Put Break off the point first on the milk run — a drop-off near 3 ft that grades prime for fall. 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.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft chart-limited; documented 2 to 8 ft | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 7 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 7 ft chart-limited; documented 6 to 18 ft | midday & dawn | Break off the point (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 7 ft chart-limited; documented 5 to 15 ft | midday | Main-lake point (7 ft) | Tip-ups, Large jigging spoon |
Count 3 structure marks on this chart. The deepest, Main-lake point, sits near 7 ft.
Cothelstone Park Lake is about 7 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 Cothelstone Park 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 6 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.
