7,181-acre river near Werkendam. The river tops out around 44 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Boven- en Beneden Merwede draws 9,486 acres inside 51.7 miles of shoreline, with 2 islands in the mix. That shoreline is heavily fingered (development index 3.8) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 64% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 16.3 mi with a 3.2-mi widest point.
