7,482-acre river near Rotterdam. The river tops out around 61 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What follows comes from the same scoring engine that paints the spots above.
The drawn outline gives you NaN miles of bank to pick apart, broken up by an island. Index NaN on the shoreline: a few honest points and pockets, nothing labyrinthine. NaN% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. For a second option, Hollandsche IJssel lies 9 mi northeast.

Spring puts european perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 8 to 28 ft; cold water stacks them in 12 to 33 ft. Measured depth break is the standout, a drop-off at roughly 15 ft, rated prime for summer european perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Measured shallow feeding flat (17 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Measured depth break (15 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Measured depth break (15 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Measured depth break (15 ft) | Tungsten jig + maggots, Small balance jig |
Spring puts zander in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Measured depth break is the standout, a drop-off at roughly 15 ft, rated prime for fall zander. Plan around the evening and early morning in the warm months. A vertical softbait over humps or a deep crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Measured depth break (15 ft) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Summer | 15 to 35 ft | dusk & dawn | Measured depth break (15 ft) | Vertical softbait over humps, Deep crankbait |
| Fall | 12 to 40 ft | dusk & night | Measured depth break (15 ft) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Winter | 20 to 40 ft | dusk & dawn | Measured submerged high spot (37 ft) | Vertical jig / mormyshka with bait, Slow blade bait |
Early season european flounder use the shallows, holding in 5 to 25 ft. Summer is a 6 to 35 ft game here, winter a 15 to 50 ft one. The chart's best answer is Measured shallow feeding flat — feeding flat, 17 ft, prime for spring. Best bite is early morning and the evening. Tie on a bottom jig with spinner blade and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | Measured shallow feeding flat (17 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Measured shallow feeding flat (17 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Measured depth break (15 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Measured depth break (15 ft) | Small bottom jig |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Fall northern pike concentrate at Measured depth break, a prime-rated drop-off around 15 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Measured shallow feeding flat (17 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Measured depth break (15 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Measured depth break (15 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Measured shallow feeding flat (17 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: common carp in 2 to 10 ft. Midsummer fish sit out in 3 to 15 ft before dropping to 10 to 30 ft for winter. The spot to know is Measured shallow feeding flat, a feeding flat in about 17 ft of water that rates prime for common carp in fall. Plan around early morning and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Measured shallow feeding flat (17 ft) | |
| Summer | 3 to 15 ft | dawn & dusk | Measured shallow feeding flat (17 ft) | |
| Fall | 5 to 18 ft | midday | Measured shallow feeding flat (17 ft) | |
| Winter | 10 to 30 ft | midday | open water |

Anglers target european perch, zander, european flounder, northern pike, common carp on Nieuwe Maas. 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.
Measured depth break is the top-rated area: a drop-off in about 15 ft of water that rates prime for zander in fall. Open the map above to see every rated spot for each species and season.
For european perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
