16,264-acre lake near Harderwijk. The lake tops out around 28 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
On the chart, Randmeren-oost draws 16,106 acres inside 81.9 miles of shoreline — 8 islands included. A development index of 4.6 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 80% of the surface — that's where the groceries are. Tip to tip the water measures near 24.5 mi with a 4.3-mi widest point. The nearest mapped water is Puttenerbeek, 8 mi to the northeast.

Spring puts european perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 8 to 28 ft, wintering in 8 to 28 ft. Fall european perch concentrate at Deepest basin, a prime-rated deep basin around 19 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
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 | 3 to 12 ft | midday & dawn | Feeding flat (11 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Deepest basin (19 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |

Sharp break is the standout, a drop-off at roughly 11 ft, rated prime for fall northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
