39-acre lake near Gloucestershire. The lake tops out around 17 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Cotswold Water Park Lake 12 draws 39 acres inside 1 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. About 92% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone.
When the water first warms, brown trout slide up into 2 to 17 ft. Summer fish stay in 5 to 17 ft, and winter fish hold in 2 to 17 ft. Start at Break off the point. It's a drop-off holding about 8 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 17 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 5 to 17 ft | night & dawn | Break off the point (8 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 3 to 17 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 2 to 17 ft | dawn | Break off the point (8 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 5 to 17 ft; cold water stacks them in 5 to 17 ft. 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 you'll meet the bite. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.
| 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 17 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 5 to 17 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 5 to 17 ft | midday & dawn | Deep basin (14 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 5 to 17 ft, wintering in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3-ft range, prime in spring. 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 | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
