Pleasure-craft are urgently requested to use the channel parallel to the "Vaargeul langs Pollendam".
The yellow floating beacons mark at least the 1.8 depth contour.

If you can not use the recommended recreation track along the yellow buoys of the Pollendam, it
is essential to keep 30 metres clear of the dam. Mind the cross current which occurs when the dam
is flooded; depending on the current direction it may set you towards the dam.
