1,481-acre Great Ouse. King's Lynn to The Wash fishing map with Environment Agency multibeam/SurfZone ODN contours (96.43% measured, 96.43% assessed), four measured spots, exact EA TraC occurrence, three dated survey cards, official access and current GOV.UK/Eastern IFCA guidance. The water tops out around 23 ft. The depth chart comes from Environment Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 1,476 acres, worked by 32 miles of shoreline, broken up by an island. With a shoreline index of 5.9, this water is all arms and coves — edge habitat well beyond its acreage. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The basin spans about 6.1 mi end to end and 2 mi across at its widest. If the bite dies, Stradsett Hall Lake is 12 mi to the south.
When the water first warms, atlantic herring slide up into 5 to 23 ft. There's no big seasonal slide here — summer means 7 to 23 ft, winter 7 to 23 ft. Start at Deepest directly measured basin cell. It's a deep basin holding about 23 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a herring feather rig or a small silver jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 23 ft | dawn & dusk | Directly measured upper-flat transition (8 ft) | Small herring feather rig, Micro jig rig |
| Summer | 7 to 23 ft | dawn & dusk | Deepest directly measured basin cell (23 ft) | Herring feather rig, Small silver jig |
| Fall | 6 to 23 ft | dawn & dusk | Deepest directly measured basin cell (23 ft) | Small feather rig, Compact silver spoon |
| Winter | 7 to 23 ft | midday | Deepest directly measured basin cell (23 ft) | Small silver jig, Sparse feather rig |
The spring pattern is a shallow one: european flounder in 5 to 23 ft. The depth story barely changes: 4 to 23 ft through summer, 7 to 23 ft in winter. The spot to know is Directly measured upper-flat transition, a feeding flat in about 8 ft of water that rates prime for european flounder in spring. Plan around early morning and the evening in the warm months. Summer baits: a bottom jig with spinner blade gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 23 ft | dusk | Directly measured upper-flat transition (8 ft) | Small bucktail dragged on bottom |
| Summer | 4 to 23 ft | dawn & dusk | Directly measured upper-flat transition (8 ft) | Bottom jig with spinner blade |
| Fall | 5 to 23 ft | dusk | Directly measured upper-flat transition (8 ft) | Compact bottom jig |
| Winter | 7 to 23 ft | midday | Deepest directly measured basin cell (23 ft) | Small bottom jig |
Spring puts european smelt in skinny water — 3 to 23 ft is the zone. Summer fish stay in 7 to 23 ft, and winter fish hold in 7 to 23 ft. Deepest directly measured basin cell is the standout, a deep basin at roughly 23 ft, rated prime for summer european smelt. Plan around early morning and the evening in the warm months. A tiny vertical spoon or a micro jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 23 ft | night & dusk | Deepest directly measured basin cell (23 ft) | Micro silver jig, Tiny feather rig |
| Summer | 7 to 23 ft | dawn & dusk | Deepest directly measured basin cell (23 ft) | Tiny vertical spoon, Micro jig |
| Fall | 6 to 23 ft | dusk | Deepest directly measured basin cell (23 ft) | Micro jig, Tiny silver spoon |
| Winter | 7 to 23 ft | dusk | Deepest directly measured basin cell (23 ft) | Tiny glow jig, Micro ice spoon |
Early season whiting use the shallows, holding in 6 to 23 ft. Even in summer they hold at 7 to 23 ft; winter keeps them in 5 to 23 ft. The chart's best answer is Directly measured lower-channel shoulder — channel edge, 12 ft, prime for spring. Best bite is early morning. Tie on a small vertical jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 23 ft | dawn & dusk | Directly measured lower-channel shoulder (12 ft) | Small silver jig, Two-hook feather rig |
| Summer | 7 to 23 ft | dawn | Deepest directly measured basin cell (23 ft) | Small vertical jig |
| Fall | 4 to 23 ft | dusk | Directly measured lower-channel shoulder (12 ft) | Small silver jig, Sparse feather rig |
| Winter | 5 to 23 ft | dusk | Deepest directly measured basin cell (23 ft) | Compact vertical jig |
Early season european plaice use the shallows, holding in 5 to 23 ft. Even in summer they hold at 3 to 23 ft; winter keeps them in 7 to 23 ft. The chart's best answer is Directly measured upper-flat transition — feeding flat, 8 ft, prime for spring. Best bite is early morning and the evening. Tie on a light spooned bottom rig or a beaded trace and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 23 ft | dusk | Directly measured upper-flat transition (8 ft) | Beaded flowing trace |
| Summer | 3 to 23 ft | dawn & dusk | Directly measured upper-flat transition (8 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 5 to 23 ft | dusk | Directly measured lower-channel shoulder (12 ft) | Beaded bottom trace |
| Winter | 7 to 23 ft | midday | Deepest directly measured basin cell (23 ft) |
In spring, common sole run shallow here, mostly 5 to 23 ft. Summer keeps them at 2 to 23 ft, and they winter in 7 to 23 ft. Directly measured upper-flat transition is the standout, a feeding flat at roughly 8 ft, rated prime for spring common sole. Time it for the evening. You won't need more than a light rolling-lead rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 23 ft | dusk | Directly measured upper-flat transition (8 ft) | Tiny bottom jig |
| Summer | 2 to 23 ft | dusk | Directly measured upper-flat transition (8 ft) | Light rolling-lead rig |
| Fall | 5 to 23 ft | dusk | Directly measured lower-channel shoulder (12 ft) | Compact bottom jig |
| Winter | 7 to 23 ft | night | Deepest directly measured basin cell (23 ft) |
