520-acre lake near Gaastmeer. The lake tops out around 10 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 is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 518 acres of water rimmed by 6.9 miles of bank. That shoreline is heavily fingered (development index 2.2) — bays, points and pockets everywhere, which multiplies the fishable edge. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 1.6 mi, about 1 mi across. The nearest mapped water is De Hop (Oudega), 1 mi to the north.
