Rhine · km 655

Measurement—cm

The GlW is 142 cm and the fairway depth maintained below it (TuGlW) is 250 cm; after deducting 30 cm of safety margin the official rule of thumb comes out at Bonn +78. In practice Bonn +78 is used here. This gauge has one forecast source: the 2-day forecast from the Hochwasserzentrale Rheinland-Pfalz (red). Upstream lies Oberwinter, downstream Köln.

The biggest bottleneck here is the Wichelsgrund, just downstream of the Kennedy Bridge in the middle of the fairway, just like the Deutzer Platte across the full width of the fairway, but deeper. Officially, the bottom lies at Bonn Gauge + 108 cm.
