11,950-acre river near Willemstad. The river tops out around 86 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. Here's the year, species by species, as the scoring engine sees it.
The chart traces 88.6 miles of shoreline here, with 3 islands in the mix. A development index of 3.8 means a maze of bays and points: far more casting targets than a round bowl of the same size. Littoral water — the productive band under ~15 ft — makes up 41% of this chart. Figure 21.3 mi of water from one end to the other, 9.1 mi at the beam. Volkerak sits 9 mi southwest — the closest neighbouring chart.
