5,851-acre river near Geertruidenberg. The river tops out around 32 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. Every species below gets its seasonal read from the same numbers driving the chart.
The chart traces 31.3 miles of shoreline here. The 4.1 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 36% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 12 mi long by 2.6 mi wide at the broadest reach. The nearest mapped water is Boven- en Beneden Merwede, 8 mi to the northwest.

In spring, european perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 10 to 32 ft for winter. Spring european perch concentrate at Measured shallow feeding flat, a prime-rated feeding flat around 9 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|

You won't need more than a bucktail or a weedless spoon over cabbage most summer days.

Bergsche Maas is about 32 ft (10 m) deep at its deepest point. The depth chart here comes from real state fisheries GPS surveys, so the contours reflect measured depths.
Anglers target european perch, zander, northern pike, common carp on Bergsche 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 shallow shoal is the top-rated area: a gravel shoal in about 14 ft of water that rates prime for zander in spring. Every other rated spot, per species and season, is on the map above.
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.
Fishing on Bergsche Maas is regulated by the Sportvisserij Nederland (VISpas & VISplanner). Check the official Netherlands regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
